    Question H-Temp kill

    After all my mods I'm getting a completely random H-Temp alarm then it goes away after 5 seconds and I'm fine. I can run WOT for 1 minute and it will kill me OR sometimes it takes 30 minutes. Sometimes it doesn't happen at all.

    Is it the sensor above the waterbox? We cut, gutted and re-welded it. I'm having issue after issue

    Did you leave anything inside the waterbox? Someone on here just had an overheating issue because of baffles breaking loose and restricting the exit. Same symptoms, random overheating. The old greenhulk waterboxes had the same issue with the baffle plate breaking loose.

    I thought about that ahead of time. I cut a massive square hole in the baffle and left enough material so all 4 welds would support each other. Nothing is broke loose.

    I'll replace the stupid sensor. I don't have a plug to try running it open air. know the size off hand?

    You can hear it coming out the through hull when it's on the hose though. My buddies 05 XP did the same thing as yours and it was audible. I listened to mine and heard nothing.

    Its M10 straight thread with crush washer but 1/8 NPT will work or a cut down M10 bolt. Also the one in the head is the same maybe swap them and see if the problem transfers.
