I got this rebuilt 440 hp .030 engine --- Fires up runs great. BUT under normal driving conditions she overheats - temp goes thru the roof.
Tried changing the water pump and the thermostat had no effect.
The radiator is hot on the bottom and cold at the top.
TOOK the thermostat completely out and temp stays at 170 degrees - but I know that is not the correct solution.
What is going on?
you already answered your question.cold at top hot at bottom =radiator flow problem. have it flow checked and quit guessing. Oh and get a temp gun it helps speed the process.And the fact it runs 170 without the t-stat also points to the radiator.Also buy a service manual. It gives you step by step diag.
