how old is rad.?? could be clogged,?? when car is at eng. temp. feel around the rad. any cold spots mean there is no flow there, then don't trust your gauge get another to be sure,and yes there are high pumps [eldebrock] has them-how old is your clutch fan when motor is at eng. temp see if fan is spinning well producing alot of air clutches go bad. and a 160 stat is good to make sure you have no air in system before you cap up. vin ----- Original Message ----- From: Trooper To: [EMAIL PROTECTED] ; The Chevelle Mailing List Sent: Saturday, May 31, 2008 9:01 AM Subject: Re: [Chevelle-list] Is there really a "high flow water pump?"
Dropping the temp of your thermostat will not affect an overheating problem. ----- Original Message ----- From: Jim H.

Test show that if you have the proper capacity radiator that copper vs aluminum is a break even. Go to a 160 thermostat, flush the block, make sure your hoses are not collapsing inside (do not take out that bottom spring). Test the pressure of your radiator cap that's important for your over flow system. If you have a clutch fan replace with an aluminum flex fan. Make sure your fan blades come to the back lip of your shroud.

Hello all...I have a 71 SS 402 and I am still fighting the summer time over-heat monster. I plan to order an aluminum radiator soon but I remember someone telling me that the so-called "high flow" water pumps are no better than a standard water pump. My overheating seems to really occur at idle (stop light, traffic, etc.). So here is the question: Has anyone really found a high-flow water pump for my car and if so, where can i get it and how much? Also, do you think the aluminum radiator will help?
