There’s not one. There is air in the system.

2018 Polaris ranger 900 xp with 1054 miles starter fried and scag one way bearing out. Does anybody know of a heavy duty one that maybe available.

Ended up being leaking head gasket. Liquid would get steaming hot then no water movement. That’s why it would never allow fam to come on.

After hooking up fuel pressure gauge had 80 psi one time then 60 and bleed off to 20. Replaced injector and map sensor good to go. Injector leaking off flooding cylinder at any given shutdown. Then wouldn’t start again till plug change.

Gee thanks for all the responses. Sure a lot of help. Figured it out anyway. Thanks again

Mossimo 500 efi utv stalls after startup loads up real bad. After it clears up it runs fine. Then kill it it might start but have to feather pedal. Fouls plug , Unhook injector, and fuel pump , replace plug, hit it with startin fluid till it starts. Plug all back in. Good for a bit. Cleaned 02 sensor, injector,map sensor, idle control valve, set valves, please tell me what I’m missing any and all help appreciated.

Thank you I will check it out. , where can I get the bolts? I must be lookin in all the wrong places cause I haven’t located any.

I don’t think oem are that great after looking at what was on water pump. Gasket didn’t even cover the hole surface. Made my own out of gasket material. So that’s why I ask about head gasket. It’s leaking allready with less than 500 hrs. Just as water pump did.

But use new head bolts?

Head gasket replacement, what’s a top quality head gasket to use? Should a person stud the head? Where would I find a place that sells both? Thank you for any info.

I understand operation of thermostat. The question I was asking was why do you call it thermostat housing if one is not there from factory. Impeller is going the way the engine is turning, no belts. Have bleed air, it just won’t move water to radiator to cool by fan which is controlled by temp which water not moving to radiator will not activate fan. Ordering a new water pump which I see nothing wrong with this one. It is one of very few parts that is available. This pump was put on by someone else and leaked oil and water. I pulled and found no gaskets orings. New orings installed, back flushed radiator also visually seen propeller turn with water pushing through. How’re ever I did notice impeller would move in and out like it was spring loaded. It must be springing out and gear no connecting pump shaft is only thing i can determine. How many degrees is hot? Curious cause can open bleeder on thermostat housing and it streams out.

Hisun 500 having overheating problem after water pump install. Should engine have a thermostat ? Has a thermostat housing but no stat, parts diagram showed it doesn’t. If it does where would I get one if Hisun doesn’t offer?
