Technically, this should be in technical, but since there is no 'Engine' sub forum for general engine questions (hint hint ;) )... How does one go about pressure testing the cooling g system? With the design of the surge tank with the overflow in the neck, there's no way to seal that overflow, so you can't pressurize the system (at least not with the tool I got - it threads on fine, and was able to pressurize my cougars cooling system with the same kit, no go on the trucks. Suggestions?
