As many of you have known, I have had some recent issues with my 6.5 Honda powered Kohler genset. I believe it to be a 6.5CZ (per the build sheet) The ID plate is missing, so it is like looking for a needle in a haystack. I have pretty much seem to have it running and not shutting off. However, need one help on the following:
The coolant will expand into the recovery tank, but not siphon back in. Tube is connected to the bottom of recovery tank and no leaks. ((Pressure cap was new with heat exchanger 2 years ago, Pressure Cap?))
I have attached photos of what I believe to be the high temp cut off switch and the choke switch. Both are located below the thermostat housing.
I believe this sensor to be defective, s it spins in the crimped brass boss. I cant find a description anywhere in any manual. ANy ideas of what it is and a part number?
Very helpful group here and I am thankful for all of your input!

Re: Kohler 6.5
Do you have the right cap? This should be a relatively low pressure cap - like 12-14 PSI - no more. If you are running a 160 degree themostat, you could drop it to 10-12 without a problem. I know maybe this seems obvious, but did you check the bottom of the recovery tank to make sure there is nothing down there and the hose is clear of debris? The coolant goes into the recovery tank under pressure, but there is very little suction to take it back.
Good luck!
Good luck!

Re: Kohler 6.5
Cap is what came with the heat exchanger, 13#. I will check hose again.

Re: Kohler 6.5
Chances are , if the coolant is not being pulled back to the engine then there is likely an air leak somewhere. Check the recovery hose and connectors.
The above is strictly my opinion always based on years of doing...remember to support local business , it pays back.
