Um, no. You don't want to go beyond 50% Anti-freeze as glycol isn't as good a coolant as straight water. Thus, you could introduce a cooling problem by using a 70% mixture. Maybe, if you live in ND, WY, or some other place where it gets really, really, really cold, you might want over 50%...

You don't need to remove all the water from the block, you just need to remove 50% of the water so you can add enough coolant to get to the optimal 50% concentration of coolant to water ratio. Look up the total volume of coolant in your system. Drain the radiator from the petcock, if the...

Unless you are trying to get the maximum HP out of your engine, do not run a 160 degree thermostat. Engine wear DECREASES as temperatures rise, an engine running at 160 degrees will have four times as much wear as one running at 180. Clearly if an engine becomes too hot can lead to serious...

I don't know why I'm joining in but here goes. First, the notion that you need a thermostat to slow down the water so that heat exchange can take place is utter BS. This wives tale has been around for ever, and won't die. Even if the water goes through the radiator twice as fast and only...
