I took the nova out for a ride after work today. While on my short ride I glanced down at the guages and noticed that the temp was at 180.

Pulling into the driveway it was at 220degr :eek:

I started to panic when I saw tiny mico bubbles at the water crossover on the intake and did the worst possible thing!
I ended up getting a small burn on my wrist when the cap blew out of my hand.
After I checked myself out I went back out to the car to see wtf happened.

I removed the stat and it started to close so that appears normal.

Must have been the lower hose froze as I had a weak mixture in the rad.

I put the t stat housing back without the stat and the temp just gets above
100degr but the upper hose doesn't seem to get firm.

I'm guessing that it's not getting hot enough to build pressure in the system.

No oil in the rad or antifreeze in the oil.

Tomorrow I will borrow my buddy's pressure tester to check it out.

What is the procedure for this test?

Hopefully there will be no damage, head gaskets or cracked head or worse the block, if any the intake manifold.

It did run funny afterwards...but I think it was the carb starting to ice up as there is no heat crossover and temps in the low teens.
I had that happen to me a long time ago.

Keep your fingers crossed.

I can't believe i was so stupid! :eek:

Rad Pressure Test

Fill the cooling system to the proper level and attach the pressure tester to the rad . Pump it up to 12-15 psi and it should hold the pressure steady. If the pressure creeps down you have a leak somewhere .
Don't forget to test the cap.

I've gotten mine above 260 before without damage as well. I think icing would be a lot worse than getting it a little hot.
