Anti Freeze

I snugged down the two bolts on the thermostat housing and tightened the upper hose clamp just a turn. It seemed like the problem was solved.

 

My Vette sat unstarted for a week while I was away on vacation. Today I started it and let it run for 10 minutes. Then I noticed the antifreeze puddle behind the thermostat housing and also along the inboard side of the passenger side valve cover.

 

Any ideas for an amateur like me?

 

 

I just gave it another look and that makes perfect sense. I'm thinkin' this is something I'll do myself right here in my driveway.

Me and my Craftsman DIYer tools got this job all finished up today.

I even put in a valve on each heater hose to cut down on scorching my feets on those hot days.

Thanks for your input!

I removed the thermostat housing. (It's a chrome one with a round robber gasket on the bottom.) I pulled off the rubber gasket and used a Fel Pro gasket with some sealer on both sides of it. I reinstalled the thermostat housing and kept an eye on it while the motor warmed up. No leaks.

However, after driving the car home I let it sit in the driveway with the hood open to cool down. After about an hour of coolong the darn intifreeze is leaking from between the thermostat housing and the intake manifold.

 

Any suggestions?

I removed it and hoped that the standard gasket would work better.

Today, while all dirty and sweaty, I had the thought, "It still beats workin'."

 

Can I buy a new "O" Ring at just about any auto parts  store? Or should I just replace the whole Thermo. Housing that does not swivel?

 

P.S. The intake manifold is an Edelbrock, if that's any help.
