just bought an 1999 500 sportsman and is ticking kinda loud got it home water pump is bad and fan not kicking on whats it gonna cost me to rebuild the top end roughly ? hopfully the crank is not hurt its only got 436 miles on it if its the original speedo only paid 1000 for it what do ya think?

 

For a thousand bucks,looks like You got a good deal.
What kind of a ticking noise???possibly valves out of adjustment???

 

it might be , i think its a wrist pin its a little bit more than a valve tick or i should say louder thanthan that and its not really a knock

 

i would a compression check. is it buring oil? maybe try checking th valves. w/ that many miles there shouldnt be to much wrong unless they put it under water. i would try to unhook the fan and run 12 volts to it to see if the fan it self works. imo

 

Agree with all said above, but the fan sensor on the lower portion of the radiator is a known problem in that era SP. Sensor dies, fan no longer kicks on, you overheat. Apply 12v to doublecheck the fan is ok... if it is, then 99.9% chance it's that sensor. also, if the fan is dead, you can order the OEM replacement direct from SPAL for a LOT less than buying through the dealer - same exact fan.

 

give me a link to spal and where is the sensor located at ? i thought it was located at the top of the radiator below the cap got a pic dont have a service man. yet been a while since i worked on a polaris and where is the fuses and breakers at? not under the seat where i thought they would be

 

SPAL USA

For a 2000 SP500, the fan is SPAL pn# 30100452, or polaris pn# 2410123
SPAL USA
$79.45

Same part from Polaris (verified on Partsland.com) is #2410123 for $238.48

This was for my 2000 SP500... and when I pulled the old, OEM fan off the quad, it even had the SPAL sticker with the SPAL part number on it. It's the exact same fan, minus Polaris being the middle man.

According to Partsland, your 1999 SP500 uses a different fan. Polaris # 4170013 for $229.31. I'm not sure if that motor is also SPAL or not. You'd probably have to pull the fan off and check for OEM manufacturer and a pn.

 

This is the cooling system diagram for a 99 SP500. The fan switch is #6. Different pn and location than in 2000.

i have a 2000 scrambler 500 and my fan suddenly stoped working one day, i took it apart and turned out the brushs were really dirty and wet. cleaned it and it works like new. very easy to do

 

im gonna tear into it this weekend . this thing dosnt have a regular fuse bank or maybe there somwhere im not looking . im gonna take the fan off and put 12 volts to it to accualy works or not then narrow it on down
