160 stats were for alcohol vs gycol at least 180. lower temp can lead to sludging of oil. If origional called for 180 degrees that is why. a 160 stat for your engine is incorrect, look for other problems. gm66

Date: Mon, 2 Jun 2008 20:20:36 -0400 I disagree about flex fans, I have used them for thirty years. I have had factory blades come off and slice through steel fan shrouds. I feel clutch fans cause drag, lose horse power and shorten pump life. Don't get touchy about the 160 thermostat they make them for a reason. A stock set up is great if everything is factory specs.

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?
