if it is not one thing..it is another thing...why don't they build them better for petes sake.... #$%&* Ran my 600 today,put on nearly 50 miles.All was ok until I was like 20 miles from the house..the temp light goes on.Now I was doing some long wot pulls on the river with like 5 to 6 inches of snow on top....that is fine.I stop to check right exchanger..it feels hot..so I drop the scrathers and start riding in the deep undriven snow.Light still remained on for a while..got concerned now.Finally it stops flickering and goes off.I basically keep the speeds down until I got home..running ok yet..I get in the driveway and stop the sled..let it idle for like 30 seconds and light comes back on.... :o| The engine heads are HOT to the touch.I shut it down.Both side exchangerrs and rear one are cold..wtf now!!!Hose from head going down to exhanger is hot..hose from the water pump that goes under the clutches to the left exchanger is cold.Now what is going on here.This sled was bleed some nearly 800 km's ago and all of a sudden no circulation...WHY would this even happen now.??The hose connected to the pump..is that the intake hose..and the pump pushes coolant back up to cylinders and back to the right exchanger and around again..
I will have to try bleeding the system again..but why would this even be an issue now..don't understand this..could of melted my motor today... #$%&*

oh yeah,there is coolant in the bottle,nothing has gone down there.

Had to be an air bubble in there doug or waterpump maybe?

lol at the thread title,

light went on ,after a few hard runs.Then I got it to go off again..made it home with no issues..then light comes on again and the exchangers are cold..so must be a bubble.Can't see it being the pump.That runs of the same shaft as the oil pump,and sled is using oil when I rode today.No discoloration damn..
Will be warm tomorrow pm,will take seat off,remove bleed screw and try to get her to work..if no go..then sled gets parked for the rest of the winter.I ain't pulling motor out again...that is a summer job ..

now if I could only get the SRX back together..I might have a sled to ride this weekend Scott.Oh yeah,I ran across Jordan today at the C0-0P.Said he wants to come down Saturday and his brother in law to be will bring his CAT down also.

Wonder what hes doing all the way over there? I still got spare bottom end here too dont forget ;)!
Jacks not answering now but I will get ahold of him to order that part yet. I shoulda told him to tell them to order instead of waiting.

pull your plugs see if they have antifreeze on them maybe u have a cracked head or a bad head gasket or try taken the cap off the radiator hose and see if there is flow when running

Blue see if your circulating coolant,remove the cap wile running,hard to see why it was bleed working fine now it's not. impeller on pump could have came off(nut).

see if your circulating..
 
i would think if the nut came off the shaft there would be a leak from the pump. what about a blockage? or as stated a head gasket leak one way on compression, ive seen it.
 
I was thinking air lock or bad pump impeler also. Remember, we are talking about a 10 year old sled, not 1 year old Yellow timebomb,tick,tick,tick,,,,,,,,,. Just say'n! lol
 
If you re used your head gaskets you my have a cracked one. I have had two on my red heads. Run good around the yard but then get temp light on after riding. Its putting comp back into water sys. But check first to see if its circulating coolant.
 
it has to be a circulation issue ,don't know why yet..Re built motor nearly 800 km ago and all of a sudden this......do not see any coolant leaking anywhere right now..coolant bottle still at same level as before.The water pump I installed new seals.oil and mechanical and the impeller was torqued and locktighted the shaft and screw.Will get the sled putside tomorrow when it is warmer and try bleeding again...this sucks.I will go and check the plugs right away and see.
 
pull the thermostat and check mine came apart in my XT and did almost the same thing i could get the light off but it wouldn't let the coolant circulate good, if you hit a ton of snow you could somehow manage to cool it down.

Pull the thermostat out and it was in pieces blocking most of the flow..
 
there is no thermostat in the SX600R's..just straight circulation.So I took the coolant cap off from the hose and ran the motor.The pump is working because coolant is circulating..that is good news... ;)! Now I ran the motor on a stand in the garage for around 20 minutes or so..leaving cap of and removed the cap of the bottle as well.Put a log of rags around the hose and revved motor up more to get coolant moving good,then I put the rad style cap back on and revved the motor right up and ran her a little while longer.The right,rear and left exchangers got hot and temp light did not come on.Took my remote digital thermometer and checked exchanger on all sides and they were heated up.Pointed at the hoses add they were hot.Took temp of the heads and they were around 150-155 F also.So coolant is moving and pump is pushing it.... ;)! Now after this I shut her down and the coolant bottle dropped down 2 inche.Actually my level was about 2 inches above the mark and now it is darn close to the mark.Could it be that I had an air lock all this time..like for 760 km's of riding and didn't know.It has been cold most times of riding.But today was the warmest day so far..-3C out and the long pulls I did..it finally shows up..don't know.
Tomorrow I will take her out again and give her a little to see if temp light will kick on and will check the exchangers to make sure they are warm before I ride..just to make sure...
 
another question to you guys.On warmer days..will a motor over rev a liitle more then on a colder day..just wandering.My rpms at wot are around 8500-8600..stock weights with 4.5 inner and 4.3 outer(drilled hole in rivet) with red spring at 80.I was thinking of just replace tip rivet with a new 4.5g in each weight(not much)..but may get rpm to dead on 8400-85-- wot...or just leave it as as.What would happen if I change secondary spring to green at 80..will it change rpm's to much.I think in the deep snow when I pin it with the red spring..I can hear like a grinding/slipping sound..perhaps belt slipping..When iI hear that I let of the gas a bit..doesn't sound normal..but this is in deep stuff,..
