P500 Overheating Problem solved

[Satellite]

I’m having trouble with overheating on my 2016 p500 go a ride about 5 miles or so it overheats my over flow tank is about 3/4 full i can pour it back in get the nose end up and rib it up a few times temp goes back to normal good for another few miles. Things I’ve done so far new radiator cap , thermostat, water pump, temperature sensor and pressurized the head no leaks , flush the radiator and block check all hoses blockages all clean. Any help with this would be highly appreciate.Here a little more background on this p500 trade for this it was in bad shape when I got he was non running had a heater in it before I got it this was a winter project for me removed roll bars painted the frame roll bar back in January had a bad accident working on it a chair I was using broke and cut my finger off from my first knuckle broke bone in three places 2 hour surgery truck lot stitches they was able to save my finger. around mid February before I could start working some on it again clean wash flush everything on this machine this is all the stuff I’ve done to this to get it running new stator pickup coil , gear position sensor, angle sensor, o2 sensor , rear axle seals , this machine runs like a champ and uses no oil Thank you all for helping me try to figure this thanks again

Did you bleed the air out? Also are the radiator fins clean? Only time I had overheating was a mud caked radiator. Best of luck.

Here is a good thread about testing the fan circuit

P500 - How do you test the cooling fan

Is there a way to force the cooling fan to come on, to test if it is working? I have never seen my cooling fan on, however I don't look that often. Is there If not how long would I need to let it idle on a 90 degree day for the cooling fan to come on? How many bars before the cooling fan...

Yeah, my guess would be air in the system.

I’m also going to go with the radiator fins are blocked. For being a 2016 and mileage is unknown to us the reader. Muddobers will build a nest anywhere. Spray the front radiator with simple green or mean green or purple power. Let it soak a hour spray it again. Let soak again. Then rinse it off real good.

And your 100% sure on that?
used a pressure washer on it?
weve seen this many times, comes down to a full or partial plug in spots that couldnt be easily reached.

thanks for posting pics but a closeup of radiator fins is more helpful - i am not convinced

-fan comes on?
-fan is blowing towards cab?
-you do see the coolant circulating with cap off?

It’s clean

Fans works it’s circulating got me puzzled using peak Honda blue antifreeze

Air in the system.

 

[Glock21user]

I agree air is the issue..keep burping it slowly and it will resolve.

 

[DRZRon1]

did a heater get installed at some point?

agree with air - had a bunch of rzrs I put heaters in, had those front ends jacked up as high as reasonable, radiator cap off, get hot so tstat opens and fan cycles - let sit overnight, rinse and repeat - damn bleeder screw was almost impossible to get to

could see air bubbles coming to radiator fill every time until all air out

This ^^^^^

A cooling system isn't that complicated. If your radiator is clean, the fan is turning in the correct direction, the thermostat & wp are functioning correctly, well that's it. You say it's circulating so you don't have a hose or pipe that's collapsed. There's really nothing else. Have you tried to bleed the system at the bleed screw, #3 in the diagram that @Mudder posted?

A blown head gasket can cause pressure in the system and overcome the rad cap to push the coolant into the overflow but this usually happens before the engine temp gets hot.
