Hello, 402 Big Block. Temp gauge showing signs of overheating. Checked everything out only to find about a pint of coolant leaking from the overflow tube. Assumed it was the thermostat, and replaced with a high performance 160 degree thermostat.
It is running great and not overheating, however when I kill the engine the overflow starts dripping. Never had a problem before and just curious what is going on. Thanks to all!
