Hi all!!
I have been working on my '76 Cadillac hoping to be able to bring it to the International Meet. This coach has had a problem with running hot since I got it 11 years ago. I am just getting it back on the road after sitting for nearly 10 years due to this frustrating problem!!
Among the other things that I did to this car before I took it to the Kingston PCS Show in 2000 are as follows:
Flushed entire block and heater core, crawled under car and even removed the small threaded plugs on each side of the block.
Installed new radiator, I would have to check but I think it is only a three core as THAT is the radiator the parts store listed, I think the one that came out (I think I still have it as well) may have been a four core.
Installed new thermostate ( 190* I believe)
Installed new clutch fan
checked/adjusted timing (after replacing missing/broken plastic timing scale)
I just got plates and put it on the road and took Jill out for icecream last night (first time she has riden in it even though it has graced her garage for the last 10 years!! lol!!) and as expected it is still running HOT.
In getting her ready over the last several weeks coolant level and FLOW were checked and found to be fine.
There is no evidence of oil in the coolant nor coolant in the oil.
I installed some gauges (electric) and it seems to run between 200 and 210, and will gain about 20* after shut down.
1.) WHAT is an acceptable temperature for this engine (500 ci) to average??
I always thought it should run at the temperature of the thermostate.
2.) I have been told to REMOVE the thermostate completely, is this OK??!!
Will doing this do ANYTHING?? (car is NOT driven in winter.)
3.) I currently have 20w50 engine oil in it, would putting it back to 10w30 make ANY temperature difference??
4.) any suggestions?? I have had this car for SOO long and I just want to enjoy it!!!
The engine comaprtment gets very hot, the leading edges of both front fenders outside are very hot, passenger floor above Catylitic converter is also uncomfortably very hot (is not plugged as exhaust comes out just fine)
time is running short and I want to be able to go to the meet, enjoy the meet AND make it home safely!!
