2011 M8 Coolant Cap problem HELP

IA ditch banger · Nov 21, 2015

I was riding my sled around and rolled it not serious or anything at all just a slow roll down the ditch and the coolant cap somehow came off and coolant leaked out everywhere. I eventually found the cap and it wont screw back on! The threads seem to be find on both cap and fluid tank. It is a plastic cap. HELP:face-icon-small-fro

There has been a problem with them warping. I can't remember where but I bought a small aluminum ring and placed it inside to keep it round .

The warping rings are for the oil reservoir. I don't think they're the same size cap/hole.

Push real hard while screwing it. No joke... It will catch and tighten up. If you don't have the ring for the oil tank, you will need it.

Had the same problem with an M7, threads were screwed up and the cap would not stay on. Ended up buying a new coolant bottle, It wasn't very expensive

Bend the metal tabs on the coolant cap in a bit, had to do this on my m7 and my '14 m8. Haven't had an issue since

Got It

I figured it out. It is a plastic cap not the metal one and you have to push down very hard and twist about half a turn at the same time and it should stick on. IDK if thats the right thing to do put it stayed on and I went riding pretty hard and it stayed on so I guess dont fix what aint broke.

That's how mine is on my '09, and it's the same as the caps on both my GMC trucks. You have to overcome the stick on the o-ring to get it down into the threads. It will come off just as hard after you screw it on, and you'll have to pry it off after the threads disengage. The O-ring should have been farther up the cap, or the threads on the cap should have extended down farther. Design fail on someone's part...
