Engine running hot
So my 289 started running hot all of a sudden. I know it's been hot here but the temp gauge never moved near half let alone 3/4. I have a high flow 180 degree thermostat. I tested it on the stove and it opened right where it was suppose to.
So I took off the radiator cap and ran the engine. I did not see the radiator empty when it opened. Actually I noticed when I rev the engine the flow increases inside the radiator. That tells me is open but It tested fine.
The engine is newly rebuilt but the radiator is original. I am wondering if the radiator is not cooling it enough so the thermostat never gets cool enough coolant to close. I am leaning toward replacing the radiator.
Anyone have any thoughts on it?
