I’d like to wind this up but, there are some loose ends.
The actual cause was a very unusual split in the bottom radiator hose. It wasn’t the usual, break at the clamp, or on a bend. It was a length wise split at the very bottom of the hose. It was large enough to dump most of the contents of the cooling system in a matter of a couple 100 feet, mostly likely most of it at the traffic light where I saw the odd maneuvering of the cars behind me.
So, thankfully, it’s not a freeze plug or anything major. But I’m not out of the woods yet.
Why not? There is often collateral damage when a car over heats and with at or near 300 degrees, other things start to fail. Some gasket materials will melt, other fluids can get broken down to make them less effective.
The major concerns with my Vette will be the gaskets for the heads and the transmission fluid. The transmission fluid is cooled by running through the bottom of the radiator and if it’s hot there, the fluid follows. Breaking down of that trans fluid can lead to transmission damage and necessitate a rebuild.
The weakening of any gasket material can cause leaking of whatever it is supposed to be sealing. Head gasket leaks, will cause a loss of compression and a chance to damage the engine. In newer cars, with aluminum blocks or heads these can warp and become useless.
My Vette has iron heads and block and in this case that’s a good thing. It’s less likely that the heat had any ill effect, but there is still a chance.
Here’s a couple more Do’s after all the drama.
1. Do have your oil changed
2. Do have your compression checked.
3. Do check all the other seals/gaskets.
4. Do have your transmission fluid changed.
5. Do have your thermostat changed.
Currently I’m waiting for the compression test to done. I”ll have the results Monday (7/5) and I’ll pass them on.
The other day (7/1) was a record-setting day for me. Oh..yea..setting some personal bests, that….well….frankly I could have done without!!!!
So I thought I’d take a minute or two to jot down the events of the day, as a form of therapy, and maybe I won’t feel like having all my cars crushed and moving to a small Quaker community in PA.
Ok…. that does feel better. Now say it with me…”I’m OK and You are OK”.
So here’s the story and I’m being as dramatic as necessary!!!!
Drove my 84 C4 to work as normal yesterday………
>>>Oh..hey wait…..I did this Corvette owner thing a few weeks back…guess what it was?…..{silence….cricket…cricket….cricket..} Give up? Ok..fine I’ll just tell you. I got a personalized license plate…No..not a vanity plate that says “Studly” like my wife wanted me to get!!! {{If you only knew how funny that last statement was..my wife hates those plates, although I believe he thinks I am studly!!!}}. Nope I had to get clever, I wanted something that defined my car. You have no idea how many times I get asked…”Yo…what years is it?” My neighbor next store ask me that every time he see me outside my house…he’s 80 something…so I’m very polite about it (’cause I’ll be 80 some day), and tell him it’s a 1984, and always ask him if he wants to take it for a spin and we both laugh. (Man..you’re getting your money’s worth reading this one..three stories in one.) Any way I thought if I could squeeze the year of my Corvette into the plate and I wouldn’t have to answer it as much. ( I actually got a stamped “1970” plate at a place in a shopping mall for the front of my Mustang for the same reason…Arizona only requires a rear plate…funny..they still sent out two plates though!!!) (Geezzzeee..there’s 4 stories for ya…I don’t think I remember what the orignal was??!?!?!). The plate reads “84C4WOT”. Deciphered it means 1984 C4 (the generation) and WOT = Wide Open Throttle.
Wow was that painful to read through? Hope not!!!
Ok, back to the original post. Got to work just fine no problems. Now, this time of year it’s get’s pretty hot here is Southern AZ and I think yesterday was about 105 or 107. My work day went by as slow as it possibly could and I had to hang a little late to finish up a task. I head home and I got about 4 miles from work and I noticed the cars behind me slow down and to a little swerve in the road. If you’ve driven here in Tucson much, such things are not extraordinary, there’s a lot of weirdness here on the roads.
Approximately 1000 yards down the road I see my digital temp gauge, jump to 260 degrees. Now the 1984 C4 runs hot by factory standards. The electric fan has a factory setting of 223 degree before it kicks on…but 260…is not good…not by any stretch. And picture my expression on my face when 200 feet further it shot to 280 degrees. I’m doing about 45 and I’m in the middle lane of a 3 lane street and traffic is heavy. I know I need to pull this thing over or that which is currently going very bad..is going to get even worse. I cut off the next car where there was the smallest of a gap and dove for a Circle K (like a 7-11) parkinglot about another 500 yards away. As I pulled in to the parkinglot…my temp gauge read 299 degrees (my first new record of the day..beating the old temp by a whopping 17 degrees…”Tell him what he’s won Johnny!!” ” Well Wink, he’s won a cooked corvette and gas saving trip on the back of a tow truck!!!!”.) DOOM!!! was the only word that came to mind….ok..fine…that wasn’t the word…but it did have 4 letters.
I stopped it, turned it off, popped the hood latch and jumped out of the car to get the front lifted up…. I expected to see coolant gushing out of every place imaginable, but the engine compartment was pretty dry…I’m thinking..this is not good…nope….not good at all. There was a little fluid on the frame and a small wisp of steam, but nothing to make you think there was an Old Faithful event about to occur. I checked the coolant overflow tank and it had a small amount of fluid in it..very small, odd for something that was about to blow. I quickly checked the hoses that I could see, without touching anything….every thing was hot, and they looked fine. I could even see a portion of bottom hose, it seemed ok. I stepped back and looked under the car and there was only a very small puddle. Corvettes are pretty low to the ground which makes it hard to see anything will out getting down on the ground, but I had on white paints and when it is 107 degrees in Tucson, the pavement is about 115!!!
So what my observations imply is there wasn’t enough coolant in the car to boil…and at about 300 degree…it would be boiling!!!
There are only a couple of things that would a cause a complete drain of the cooling system.
1. A hose coming off. Since there wasn’t any coolant on the upper part of the engine, so the top ones were fine and what I could see of the bottom hose it seemed normal.
2. A cracked block or a head would have had the Vette running poorly before hand and I would have noticed.
3. Freeze out plug failing. I’m thinking this was the problem. A freeze out plug is just that, a metal plug in the block and heads of your engine. They are there mainly for cold weather climates. If the coolant was mixed wrong with too much water and should this mixture freeze, the plugs will pop out during a “freezing event” allowing expansion of liquid hopefully saving the engine’s metal from cracking from the pressure.

Freeze Out Plug in the engine block.
Why is that so bad? They look pretty simple to put back in. Sure they are, right…after you pull the entire engine out!!!
So there I stand, white paints looking soiled, red Vette with hood up and smelling like a burnt carrot, 107 degree, humid as hell, and it starts to rain. Can you picture it?
I made a quick call to my GM Motor Club and they arraigned for a flat-bed. 2 hours later my lovely wife meets me at the Circle K and we wait together for another 45 minutes(total of 2.75 hours) for a truck to show up (my second record of the day… breaking my last tow truck wait by 1.25 hours) and 45 minutes after that I waiting in my favorite repair facility parkinglot waiting for my poor Vette to be dropped off (where it would sit, in the dark, overnight, all alone and wounded). Too much drama?
Let’s get to the do’s and don’ts.
1. Do pull over in a safe spot as soon as possible.
2. Don’t continue driving. Don’t try to make it home or one more block/mile. You could just be making it worse.
3. Don’t keeping it running after you stop in a safe place. It isn’t normally going to cool it down and again you could be making it worse.
4. Don’t touch anything under the hood. Don’t open the radiator. Don’t open the coolant overflow reservoir.
5. Don’t try filling it with water or coolant immediately. Just let the car cool down all the way down.
6. Don’t try driving it after its cooled down, even if you filled it with water. 100% chance that what caused the overheating, didn’t go way.
7. Do call a tow truck.
8. Do call a friend or someone and let them know where you are, at the least.
9. Do get a motor club of some kind. Average Guy with average budget..right? Towing is expensive, very expensive. I like the GM Motor Club. I pay about $69 a year and I’ve used it twice this year already. I have my son’s car covered and my Corvette. (The Mustang is covered by Haggerty insurance.) Within town the towing is free up to a certain mileage, both this years tows were free, saving about 250 bucks a shot, that a good deal.
If you searched and found or followed my posts on restoring the dash-board of my ’70 Mustang, then you might recall my planning/scheduling issues.
As I was taking the old dash pad off, I realized that I hadn’t order the plastic pillar molding. When I finally called a few Mustang parts supplies places I found them all to be out of stock and they had to put them on back order. They did finally come in and it’s taken me a bit to actually find the time to replace them. Well, this long 4th of July week, I’m at least going to get started. (I have also do the valve cover gaskets as well.)
So here again is what I’m replacing:
Yeah..had to get creative to keep them on.
Pretty?
Now the new molding comes in any color you want as long as that’s black. You’ll need to paint the proper color. If you have the specs for you car you’ll easily find the interior color and places like National Parts Depot or Mustang’s Unlimited have the paint for the job. I had to do this with a replacement armrest. Which was horrible – replicas all came square and my Mustang’s armrests are rounded and have the overstuffed look like a leather sofa or overstuffed chair. (I ended up pick up a use one in good shape and painted that..I think it was tan originally.)
Oh..sorry…I wandered!!!
The first think you have to do is prepare the plastic for holding paint. The guys at National Parts Depot recommend SEM 38353 Plastic/Leather Prep. I’ve used it and it seems to do the trick. Pretty simple….Spray surface, pay attention to recessed areas, wipe with clean cloth. Use some gloves if you have office worker hands and put out the cigar while you using this stuff.
SEM 38353 Plastic/Leather Prep
Sticking with the SEM brand I purchased a can of Universal Color Coat. I used this paint on the aforementioned armrest and it lives up to the “Flexible Coating” label. My Mustang’s interior is VP-15945 Vermillion.
6/30/1953 – Corvette debuts at NYC Motorama. That’s a big deal. 6/30 is also my birthday. Yup…5 years later to the very day the Corvette debuted my parents had another mouth to feed!!!
1953 Motorama Corvette..And so it began!!!
What? You thought my baby pic…No Way!!!
And 11 years later to the day the last Rambler was produced that was 6/30/1969.
1969 - Rambler made a few fine cars...um...this wasn't one of them.
7/1/1908 United Motors was formed. They build car components, at one point include Hyatt Roller Bearing Company (anti-friction roller bearings), New Departure Manufacturing Company (ball bearings), Remy Electric Company (electrical starting, lighting, and ignition equipment), Dayton Engineering Laboratories Company, later known as Delco Electronics Corporation (electrical equipment), and the Perlman Rim Corporation. It was later purchased by General Motors.
Also on 7/1 the Graham auto plant in Canada produced its first Prosperity Six in 1931.

Again on the same day Pontiac selected Bunkie Knudson general Manager in 1956. Bunkie Knudson – race car driver and innovator.
Another biggie….7/2/1992 the 1 millionth Corvette was built. It was a C4 Convertible. Grabbed a picture of it at the National Corvette Museum while I was there a couple weeks back.

Hey..I’m still looking for abandon car pics. Email them to me timsweet@cox.net or drop by Average Guy’s Car Restoration, Mods and Racing facebook group. Pls include a general location.
I still have two DVD’s to give way!!! Here’s my latest.
1939 Packard. Originally from Texas, it got left here in AZ and now sits outside Boot Hill in Tombstone, Az.
1939 Packard.
1939 Packard Originally from TX.
Still got the flat head tucked under the hood.
Just needs a little TLC on the interior...yikes!!!
YEAH!!!! I know!! Where have these been…right? Sorry, but I think I’m back on track.
My Mustang has an old school 4 barrel Holley and although it starts pretty quick after a few pumps of pedal to get the mechanical fuel pump to push gas where it needs to be. But if your old school muscle car or race rod sits for a while or you swap carbs often, you can spend some considerable time cranking on the engine. This might seem like no biggie, but it can cause lobe failure on a flat-tappet cam.
For my Holley there’s a better way.
You need to locate your float-level sight plugs.
Holley - image not from my mustang
A different configuration
Take a plastic squeeze bottle…. (Do you really need a pic of a squeeze bottle?) Well just in case…
Bottle Pic you don't need!!!
this type works the best…. and fill the float bowls with fuel until it trickles…(very little trickle…no fires…please.)
Float Bowls
This should be enough fuel to allow the fuel line to fill from the tank. According to the specs a Holley can run 45- 60 seconds on full bowls.
6/22/1934 Hitler contracts Ferdinand Porsche to build cars with let to..you know the VW and later the Porsche!!!!
1934 VW
In 1958 on 6/26…just four days before I was born the first Datsuns was exported to the U.S.
1958 Datsun.
We use to laugh at them. My father and I once cut a wrecked B210 in half and replaced the entire rear and 1/2 of the roof from a donor car.
That was kool!!!
Ok. I’m no Oprah but I just finished a book that race car people will love. If you love dogs, auto racing and a good story you are going to love reading “The Art of Racing in the Rain” By Garth Stein.
Go get it. (no I don’t get paid for this…I just like it.)
6/14/1832 – Nicolaus Otto was born in Germany…”Who?” He invented the gas motor engine. An engineer and experimenter, Nicolaus Otto invented the first practical alternative to the steam engine in 1876 — the first four-stroke internal combustion engine. He called it the “Otto Cycle Engine,” and as soon as he had completed his engine, he built it into a motorcycle.
The Otto Motor powered Cycle
6/16/1903 – The BIGGIE….Ford Motor Company was established. On the same day in 1953 Ford introduced the power steering. (Two for the price of one)
Also on 6/16/1896 Jean Peugeot was born in Paris. Founder of Peugeot the auto maker. The family began with coffee mills and bicycles and then cars.
6/18/1943 Tom Gale was born in Michigan, Flint to be more exact. His Dad was a designer for Buick and his grandfather worked the assembly for Buick. Guess where he went to work when he finished school….nope….Chrysler.. Gale became head of design in 1985. He previously worked on the some of the iconic cars such as the E-bodies-Barracuda and Challenger and was a major contributor to the Chrysler Portofino concept car.

6/19/1947 the Tucker shows up in Chicago.
The Tucker-Torpedo - I love these cars!!!!
And on the same day, 1969 GM produced the 4 millionth Cadillac.
This isn't actually "THE" 4 Millionth Caddy..but you get the idea.
