So I think I blew my head gasket today....

I had to run out and pick up a prescription this morning.  I jumped on the interstate to avoid the downtown congestion.  I get to the pharmacy, no problems but when I get near the front of my vehicle, I can kinda smell radiator fluid.  No biggie I think...I just filled the reservoir a couple days ago and maybe I over filled it.

Get my scripts and jump back in for the ride home.  

Back on the interstate, no problems.

Drop off the interstate to get back on the main drag you have to take to get to my neighborhood.  No problems.

I get about 3 miles from the house and get caught by a red light....I see steam!

wtf?

So I pull off to the side and pop the hood...my radiator is blowing fluid out from an apparent crack at the top.

I had some anti-freeze with me so I refill the reservoir and bee line back to the house.

as I pull in the driveway, it is steaming and clattering and doesn't sound good.

I am letting it cool and will try to start it later.  I am not a mechanic but I used to work on all my pre 80's hot rods and I kinda know that sound....it is not a sound you ever want to hear

Thanks Wings

I think there is a problem with my fans...when I got home, before I turned it off, I popped the hood.

With redline temps, my fan should have been running and it wasn't. It could be a relay or a switch or maybe the fan motor has just shit it's pants.

I'm going to check it when everything is cooled. I'll short the switch and see if the fans start. Don't have a way to check the relays though.

I have to say as an old hot rodder....to who ever thought changing a belt driven fan to an electric fan....I want to punch you.

Cars used to be so much easier to work on

it's a conspiracy I tell ya!

I could do just about anything to pre 80's vehicles and I did!

head gaskets, timing belts, points, plugs and condensers....Hell I changed heads a few times, swapped transmissions and rear ends....

now you need a computer and a vehicle specific tool kit

I had a 67 SS El Camino with a 300 horse 327 motor I swapped the heads with a 350...bigger valves....it screamed after the change. I loved that car. Candy apple red, Hi jacker air shocks.... Crager SS rims all around....70's on the front and deep dish 50's on the back...two speed powerglide transmission...dual exhaust with cherry bomb mufflers

the only thing that car/truck hauled was ass

I got a 69 SS el camino after that

it was original big block 397

put the cragers on it (70's in the front and 50' s in the back)and hijacker air shocks...dual exhaust...cherry bombs

it was pearlescent white and had a brown and black diamond tuck leather interior

God I miss those cars

A lot of people do not like El Camnos but I promise, If you would have ever seen either of mine, your opinions would have shifted

Don't forget to check the thermostat. Let car get to running temperature and see if fluid is flowing by looking in the radiator cap opening if that's possible.

Right now I would love to get mylittle fingers on another 67 or 69 ss El Camino

the prices are just stupid now.....I think I paid 3 grand for the 67 and put about 3 grand into it....

I paid about 4 for the 69 and had a lot of carry over parts. I put the original rims back on the 67 when I sold it...which were not bad rims! Original Rally rims....center caps and beauty rings now cost big bucks

That is the problem...it is one of those pressurized sealed kinda systems. I can't open that valve cap and see into the radiatorlike we used to years ago...there is no pop off valve like we had on the 60's and 70's models

I think I over filled the system the other day and the pressure blew a whole in a weak point in the radiator

Everything is moving and there is no noise (like a failing water pump)

I think it was a disaster of chain reaction failures

I overfilled the reservoir

that caused excess pressure in the radiator causing a crack

That caused it to spray off excess fluids

those fluids shorted the switch or motors of the fans

those fans not working caused the system to overheat

The overheat cause it to raise pressure and blow more fluid out of the crack in the radiator

dominoe effect...cataclysmic, systemic failure
