In the July 2007 issue of Hemmings Muscle Machines there is an article in the Tech. section called "Cool Running: Refreshing Your Cooling System". It's nothing that is new but does cover areas that a person might not think of or just forget to do. And it talks about a "High flow water pump". There is a difference. They use a Charger cooling system but the same applies to all cooling systems. ----- Original Message ----- From: Dean Vandergriff To: The Chevelle Mailing List Sent: Tuesday, June 03, 2008 6:18 PM Subject: Re: [Chevelle-list] Is there really a "high flow water pump?"
I'm coming into this one a little late, but are you boiling over or just seeing elevated temps on the gauge? If you're not boiling over I wouldn't worry too much. My 454 with flex fan, & no shroud ran consistently at 180 idling would jump up to 200 pretty quickly, but it never boiled over. If you check your gauge 15 minutes after you shut the car off you'll likely be scared by the temp that you see & that happens every time you shut it off. But again, if it's not puking coolant all over the ground don't sweat it too much. Just my .02, or is that .06 worth at today's rates J Dean Vandergriff ------------------------------------------------------------------------------ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tom Rightler Sent: Saturday, May 31, 2008 10:46 AM To: The Chevelle Mailing List Subject: Re: [Chevelle-list] Is there really a "high flow water pump?" A 160 thermostat won't fix anything. It's overheating because the temp of the coolant is higher than that of the thermostat at all times menaing it's staying open and coolant is not staying in the radiator to cool down. There is a such thing as running too cold. Flex fans are junk...period. They flow LESS air then the RPMs are in the mid range. You should be running a 180-185 thermostat in a 402 along with a 19" 7 blade clutch fan and the correct fan shroud. GM engineered this for a reason...it works. I have a stock cooling system on my 70 SS 454 and never have overheating problems with it. Another thing that comes into play in this situation that alot of people don't realize is the size of the water pump pulley. Does it have the correct one on it? Another water pump won't fix anything if the pulley is the problem.

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?
