Hi,

Let me start from the top

Rebuilt water pump
Pee stream strong but cold
Traced all water lines- checked all lines for blockage
Ran it with thermostat/cover off strong stream of water coming from there
Ran it without thermostat


None of these made a difference
Still overheats, badly have to shut it off after like a mile. If you touch the motor by the spark plugs it feels normal but as you move down the motor towards the harness it gets hotter and hotter to the point you can't even touch it.

What I also noticed when I shut it off is an EXCESSIVE amount of steam coming from the exhaust. I know a bit is normal but it fogs out.
I'm beyond stumped.

Can you tell me if you are getting any beeps or alarms with your situation. Please let us know what/if you determine the problem/fix.
