Cooling Problems

[Ktrim]

Your local auto parts store should have pressure tester to rent. And adapters. Probably like an inport adapter, nissan or Toyota may fit your rad.

Sound slike all the 'normal bases' have been covered....so a head scratcher for sure.
It'll be nice to hear WHERE the coolant has GONE ! You'ld think that amount of coolant WOULD leave a stain or two 'somewhere' !

Surprised no one has brought this up but what’s the actual temperature?

“Dots” on the temperature gauge is just a reference. Get a temp gun and see what temperature the radiator, engine block, and thermostat housing is. It might not be running hot, just warmer than normal.

I will agree if your loosing coolant that’s another issue to solve.

The Schwaben vacuum tool is fairly inexpensive. You'll use it again for coolant changes so it's not a one time thing.

nothing in the exhaust indicates coolant there.

When you say that are you talking about smoke too?

The only thing that comes out is some smoke from startup, diesel smoke, then clears up and nothing else. Thanks!

I've got a laser temp gauge. I'll try it and see what it is. Thanks again!

I totally agree, but there is no trace of coolant at all. When I overfilled the recovery bottle one time, the excess dripped all over the mower deck and I could smell coolant. I don't smell anything and there ios no trace of coolant on the deck. I'm still scratching my head over this one. Migh have to bite the bullet and take it into service. Thanks for the ideas.
