Losing coolant

[jim riordan]

Don,

You could get a gallon container and some how wire it so that it would collect anything from the overflow tube to see if it coming from there

David, I show no sign of splash, but the rate of leak is slow enough, and the rear mudflap solid enough, that it doesn't rule out leak. At the stop where I checked the level hot I also looked underneath for any sign of
loss (engine was running) and there was none. Even so, I think your idea of getting a pressurizer for testing is the best plan moving forward.

My cap is a 13-lb cap, and is secure. I agree that last click is hard - takes two hands for me.

It has been driven 6000 miles since the upper gate valves were replaced. There was about 1 gallon replaced in the first hundred miles or so. Heater has been used multiple times.

Transmission fluid level is normal/slightly low, and is clear. I would not expect either if it had 5 quarts of coolant in it.
