OVERHEATING !TOOK OUT THERMASTAT , EMPTIED THE RADIATOR OF COOLANT AND REFILLED WHILE RUNNING - APPEARS TO BE GOOD FLOW FROM RADIATOR INTO ENGINE AND ENGINE INTO RADIATOR JUST BY GROSS OBSERVATION .LESS OF A PROBLEM ALTHOUGH COOLING BETTER AT A CONSTANT LOW , LESS THAN 50 MPH THEN AT A STOP BEGINS TO GET WARMER AND WARMER AND WARMER BUT NOT OVERHEATING ANY SUGGESTIONS ARE GREATLY APPRECIATED
Rad, is likely the problem, even though it appears to flow o.k. there is no way for you to determine if it is flowing properly other than taking it to a rad shop and having it flow tested. I would recommend installing a new or recore rad with an extra row of cooling tubes for some added insurance.
HELLO THANKS FOR THE SUGGESTION AND TIME ." RECORD RAD" MEANS? CURRENT RAD IS ORIGINAL , SO OEM OR AFTERMARKET . DOES EXTRA COOLANT ROW CONTAINED IN REPLACEMENT RAD OR IS THIS EXTRA?THANKS AGAIN
HELLO REREAD YOUR POST , MISREAD IT THE FIRST TIME. NEVER MIND , I THOUGHT SO TOO , WILL PROBABLY REPLACE AS IS ORIGNAL RADIATOR. THANK YOU
had rad core replaced with 3-coil 1/2 tubes . cools very well now
