hey guys, first of many posts to be sure. Here is my issue: saved my baby from the yard...did a rebuild on the engine, (did not change water pump and t-stat) Drove her on the hiway for about 30 minutes at 55mph, started to run a little hot, parked it, heard coolant boiling, and it puked some out the overflow hose. OK, so put in a 195 tstat and flushed the radiator. Drove her this morning about the same time and distance. Did not hear the coolant boiling but puked some coolant out (note: the coolant was FULL to the top of the radiator) I am going to put in a 180 t-stat tonight -- water pump appears to be ok. Thoughts/suggestions? Im open to anything

on the guage it reads a little past dead middle, it does not spike, the needle does not leave the little circle...

note #2, I live in south GA and it is HOT, pretty much year round, in the 'winter' it gets to 40 degr MAYBE a few days in late Dec....

thanks!

Geoff

If you are filling it to the top it will keep spitting it out unless you add in a recovery tank and keep it at the fill line on it. I did that to my 64 that has a v/8 , works good. It sounds like the temp is about right to me. I'v owned my 64 since it was a new car and it has all ways stayed about half way over on the gauge after warm up. You can all ways add in a mechanical after market temp gauge if you are unsure about the original one. You don't want it running to cold,that's as bad as to hot. You will get a lot of build up of crap running to cold. I'v used both 180 and 195 stats . How good is the radiator ? You can get bigger ones than what came in them for most cars.:)

Coolant expands when heated. That is the source of the expelling coolant. The level when cold (after expelling) is the proper coolant level for the system.

Of course a recovery tank will eliminate a lot of problems (air being drawn into the system).

Great aspect for those willing to go the extra mile for their classic! Not original, but safer in the long haul!
