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 ..

      Hi ya'll. I just got a 04 Kodiak 400 and Im confused.The left rear wheel moves like the bearing is shot so I figured its a quick fix. Much to my dismay when I looked at it before I tore into it ,it appears to have a drum brake-no bearing on the wheel. As this is the first time Id be working on a 4 wheeler job Im a bit hesitant. The manual only shows this has disk brakes.Its a sealed drum right behind the wheel.I pulled the wheel of expecting to find a bearing.Nope! Ive never done it before but it appears Ill have to pull the axle out to replace the bearing. Am I correct and if I am can anyone give me some advice on how to do it.The repair manual isn't much help. Thanks alot!

      I have a 2003 LTZ 400 that i bought a few days ago. The quad was running fine until last night. I let my brother ride it down the street and back and i didnt notice anything etong with bike. Then my neighbors friend came over and said "can i ride it?" I said "sure" so he ripped it down the road all fine and when he got back it died right in front of us. My brother said it was dieing on him also. He also said that he wasnt using the clutch to shift. I told him he was an idiot. Im throwing that in there incase that caused a problem as well. But today i go to check it to make sure its getting fuel which it is and replaced the spark plug incase it wasnt getting spark but it is. So i started it and it was having a problem starting then i got started and was reving at idle high. So i took it around the block and it died on me a little bit down, so i try to restart it and it started so i kicked it into 1st and it kinda launched on me and started going with the clutch all the way in. Then it died right after and wasnt running right during that process and was idleing all over the place and just died and now i cant get it started it again. Before it would start without the choke or priming it. It would start real quick now i cant figure if it needs to be rejetted or something else. Air filter looks clean also. But any help would be gratelly appreciated!
