2000 Polaris Scrambler 400 - Anti-Freeze Problem

Recommended Posts

I have a scrambler 400 and the antifreeze was going through after one ride and then after awhile I smelt the antifreeze burning in the exhaust. So then I changed the gasket on the piston head.it hasn't fixed the problem. Now the spark plug get ruined after 3 times of starting the atv. But there is no coolant in the plug. Any suggestions

is there coolant in the crankcase? could the head be warped? bad water pump seal? what year is this bike, a 1996?

is there a telltale hole at the water pump, and is there some anti freeze dripping? a seal is gone if there is ...

had to work on 1 of thoes that was doing the same thing ...it was the base gasket at the bottom of the jug (cylinder) .. i also replaced the water pump shaft seal and the gaskets on the water pump just to make shure they were new and not causing any problems in the future ... so i would check both of thoes just to make shure .. and they dont cost that much to do.. just the time to do it is about 2 to 3 hours ..

      I have a 1996 Kawasaki Mojave KSF250. I have no manual on it and it has a no spark issue. If anyone could give me a hand with this or would possibly have a manual would appreciate it.

      I recently purchased an 07 Honda sportrax and when I was checking the spark plug I saw the boot was ripped nearly in half. When I removed the plug it was blackened and covered in oil. How can I thoroughly clean the plug hole and remove any debris that is in there? Is there a small tube like vacuum or something of the sort made for stuff like this? The machine my dentist has would be perfect, maybe they do rentals! 😁
