I havent been able to ride yet - due to lack of snow! I was looking over my sled and tried to perform the cooling system bleeding advisory posted earlier. After 5 minutes of running the engine the runnning board was still cold so I shut her down. Anyone else experience this ? Should I just let it run longer ? Thanks.

Mine took around 8-10 minutes before they started heating up.

check how hot the head is getting.. REAL hot and you have an airlock. Did the coolant level in the tank drop after you shut it down? Are you leaving the cap at #1 position as per the bulletin?

After only putting on a few miles on my sled I've noticed that it does take approx. 10 minutes of idling time to come up to temperature. Yes, it has been re-burped according to the service bulletin. Then for the first few miles just take it easy, provided you don't have air pockets in the cooling system, you shouldn't have problems.

These sleds have a coolant bypass system where the coolant will only flow in the engine until the temperature comes up to a high enough and the thermostat opens. The coolant will then flow into the rest of the coolant lines and coolers. Only after the thermostat cracks open will you feel heat in the heat exchangers. This is also the reason why you have to fully warm the sled up when you burp for air bubbles. I hope this makes sense.

What yeti said..plus remember it is reverse cooling, left side heats up first then the right side. Due to the huge rear heat exchanger it takes 8-10 before the thermostat opens at idle, run the rpms up to around 3000-3500 to get the engine up to temp...

I've heard several times that the left running board exchanger heats up first. My right side always seems to feel warmer than the left. I've done the burping procedure and I have over 300 miles on my sled-any ideas on why this is?

I was just up on the Gunflint trail in MN with a new F-5 (not completely serviced out) and found it took a minimum of 10 minutes ideling and a couple of minutes driving slow before the right side hose leading to the right side edge grip exchanger became warm. The head was plenty warm for a long time before the coolant actually circulated. lol
