Quote: FWIW: Yesterday with a 160 standard flow thermostat, outside/ambient temps in the mid 90's (F) and cruising on the Ohio Turnpike at 70 mph. Sunday with similar conditions but a little cooler out the temp gauge needle was right on the next to the last line and the car puked coolant two minutes after I shut the engine off at a local cruise . just FYI and I have no clue on a 160 versus a 180 thermostat????

That is why they came out with burp tanks. wasn't that you were necessarily overheating but that the coolant quit circulating and pressure built up.
