    Overheated

    So I have a 16 YXZ the radiator got plugged up and I overheated quite badly/blew out a lot of coolant. I limped it to the nearest creek washed it out the best that I could and added water and the coolant/temp light never came back on so I kept driving it. But im guessing I had a steam bubble over the temp sensor as the light never came back on so it melted the crank plug, the ignition coils, and dipstick. Has anyone been inside a engine that has been this hot is there anything I should specifically look for. I am assuming the worst but didn't know if anyone had experience with anything like this.

    I wired up a fan override switch and that helped. Is the front of the radiator caked with mud or anything?

    Yes the radiator was extremely plugged so i limped it to the nearest creek and washed it out the best that i could and the coolant light never came back on so i went against my gut and kept driving it. I shut it off when it melted the crank plug and it splashed oil on the exhaust and made it smoke and towed it back to the trailer. That night i started looking at it and pulled a ignition coil out it was melted and noticed my oil dipstick was also melted. So i guess my question is has anyone severely overheated thier motor and if so what should i be on the lookout for.

    I will be amazed if you don't have substantial damage to the engine. I would imagine one of the first casualties to consider will be a cracked head, blown head gasket, stuck piston skirt and even a cracked block. I really don't know how well this engine handles extreme heat, maybe you'll be lucky and their like the old 318 MOPAR engines.

    So then assuming the worst does anyone know the best and/or cheapest way to rebuild the motor. Are there any rebuild kits out there or am i gonna have to make my own or should i just hunt around for a used motor or should i part it out and buy a new yxz

    I think it may be worth a try to get the parts needed to try and fire your motor that got hot, maybe you'll get lucky and this motor will take a severe heat spike. Did the motor quit or did you shut it down?

    If you have severe problems and it won't start, I guess you'll need to disassemble the motor to determine if it's rebuildable and what parts you need for a rebuild and if it would be cost efficient to rebuild it. A salvage motor with low mileage will run you around three grand.

    I shut it off and towed it back to the trailer so i think it just heatsinked and spiked after i shut it off but im sure it got hot before that. Yea the motors that ive seen are around 3 grand and i tweaked the frame on it about 6 months ago so i dont know how much money i want to put in the motor if the frame is already bent. I have some new ignition coils coming so in a week i will try to see if it will start/run and go from there.

    Referring to iceman post #1:
    We should all be watching our gauges better to prevent many thousands of wasted $.
    My brand new 2017 heated up a little at only 400 miles on it. So I was looking around for the reason and noticed coolant bottle empty. To make a VERY long story short, it ended up being a bad motor. Yamaha called it "metal porousity".
    Coolant was going into the oil because of poros metal casting. If I had not been watching my guages, they would have just blamed me and said I just overheated it.
    They ended up putting a complete new engine in it at 500 miles on it.
    A freak thing I'm sure. I have not heard of another like this.
    So... People... WATCH YOUR GAUGES!!
