Hi all I have a couple more questions.
I put in the aluminum radiator now the problem I am having is that the engine is running hot according to the gauge. I put in a new thermostat also. The engine was running hot with the old radiator which would be expected because it was leaking. The 54 engine has a 848 head on it and has an adapter for the temp. sending unit. I put in one that fits a 848 head but I am not getting a reading of any kind, I tried two different gagues that I have. One is out of a 55-59 I believe GMC 12 volt the other is an aftermarket. I ran a wire from the temp sending unit to the gauge then the other wire to the ignition with a fuse. I tested the hot wire and it is getting juice. Now for my questions one did I wire that correctly and the second question is Are there other causes for that engine to be running hot. One other observation is that I will run the truck for a little while and the first gauge it would shoot up to real hot for about 30 seconds or so then you could see the needle bounce back as if the thermostat had just opened. I hope I am clear enough for you to understand my problem. I have also tried running with a little less then 50/50 and also 50/50 coolant. Thanks in advance for any help.
Steve
