Being a 22 year old car the thought of getting the pressure off the system is worth considering. Have some experience with Evans from running hot Pontiac big blocks and also dirt bikes. Back in the late 70's or early 80's they came up with a water pump design the improved cooling on big block high RPM Pontiac motors. Then the stuff I know has been very very effective in off road bike racing. Never changing coolant again, a 300 degree F boiling point, no corrosion issues ever and no pressure in the system make it look inviting. Will have to change my coolant soon so looking hard at the stuff.
Anybody use it??
