Re: Pressurized Radiator
This thread has filled with a lot of misinformation. The original poster asked about mounting the overflow tank, there are only a couple of responses related to that.
If you have a leaking head gasket, water pump, or other items because of a pressurized radiator, you have other issues that need to be addressed first. Adding a pressurized system at the typical 4-7 lbs isn't the cause of the leak, it just helped you find it. If your head gasket can't hold 4-7 lbs of coolant pressure, it's not holding back 50+ lbs of compression pressure.
I'll never run a non pressurized radiator again, the advantages are numerous. Besides the previously mentioned higher boiling point (which is only 12-21 degrees higher at 4-7lbs), it reduces damaging pump cavitation, water loss from evaporation and steam, helps maintain normal operating temps at high elevations, and eliminates the mess from leaking radiator caps and atmospheric overflow tubes
