350c running warm

[Gwilkrrs]

Ran the machine for 15 min full throttle in 90* weather and when shut down it hissed and steamed a bit- damn gauge said 100* so that isn’t working……
I will check coolant level next time but I don’t know status of fluid

Anything else to check?
Troubleshoot the gauge?

The radiator cap needs to hold the correct pressure.
Test or replace-this is more important than most people Realize.

thanks
i will check fluid and then try to test the gauge. i will research the cap requirements.

If you have access to a non contact temp sensor use that to get actual engine temps.

[Gwilkrrs]

thanks-
this sounds dumb to ask but ......

would you shoot the radiator itself?

[jimmydiesel]

Take a reading at the thermostat housing-where the coolant leaves the engine to go to the radiator.
That will be the engine temp. Clean the the dirt and oil off.
You can take a reading from the top and bottom tank on the radiator to get an idea how the radiator is working.

[jimmydiesel]

If the thermostat is still closed (engine not at operating temp) check the block where the thermostat housing bolts on.

Hi,

Better yet, if you have or can borrow, a thermal imaging camera. See if there are any hot spots which indicate a coolant passage blockage.

I typically shoot the head area found out my gauge was reading about 15/20 degrees warmer than actual. Started shooting all my equipment found out how lousy temp gauges actually are. Like was mentioned i did like to shoot the top/bottom radiator just for fun to see how well all that was working.

So I only had a min or 3 to look at machine so far but I did add a gallon and a half of fluid to the radiator-

machine has sat for a couple days and I checked it without starting and added-

will check gauge next but low on fluid doesn’t help

Will let it run next and check temps
