Overheating issue on 2018 Ranger XP 1000 need fresh ideas

[SideBySlide]

I'm working on a 2018 Ranger XP 1000 that's come in with several issues, but the overheating problem is really puzzling me. I've already swapped out the water pump, thermostat, and temp sensor. I've bled the system a few times with the front end lifted, and while it does run, it still overheats. When I crack the bleed screw, it just releases air. I've pressure-tested it as well, and that came back fine

Has anyone else dealt with something like this? I'm starting to think it might be a cracked head or an internal gasket leak that's letting air into the system, but I'd love to know if anyone has encountered a strange fix before I dig in further. I'd really appreciaet any advice

It sure sounds like youve covered the common causes, so if you're still getting air when bleeding and the system still keeps overheating, a head gasket leak or a cracked head most probably is the issue, especially if combustion gases are getting into the cooling system. One way to confirm this is with a combustion leak test (block test) to check for exhaust gases in the coolant. Its not uncommon on these machines under heavy use, and catching it early can save big bucks thats for sure.

I feel like OP did a great job figuring out the causes, so the best thing to do I guess is to bring the car to the dealer after doing all that. Sometimes we think we know, but really, the experts know better.

Man you have really been through the wringer with that Ranger. @gulliverrocks doing a combustion leak test is spot on advice. Keep us posted, will ya?

Well sometimes the obvious mechanical parts aren't always the issue, have you ever checked the radiator? Could be a stuck radiator fan or a clogged radiator that's limiting cooling.

They're all making a point here man. If you're still bleeding air every time, I'd bet money it's a head gasket sneaking exhaust into the coolant. He's right on the money this guy @X-hamlet a block test kit should give you the answer fast.
