I fixed an oil leak about a month ago and haven't been able to drive it since. Last week I was able to make a run to the gas station but that was it. At a light, I noticed the temps got up to 237 and I was getting nervous. Well I confirmed last night on a longer trip as it hit 251 (F) degrees as I was stopped/moving slowly. Luckily it was a block from my house and I was able to turn it off and coast.

I put water back in the system, but its probably 25% red coolant and 75% water because I didnt "flush" the system.

How can I check and/or remove air bubble in the system that may be preventing the pump from pushing the water/coolant through?

Put it on a rear stand, take off the cap, start the motor and squeeze the top coolant hose off and on while the coolant circulates. Keep adding water until no more air burps out of the system. It shouldn't take long if that's your problem. The other potential problem is a temperature sensor going bad.

It's a squid thing. You wouldn't understand.

I had the same problem about a year ago. I did a full coolant flush and then did as Will said...squeeze the large top coolant hose during idle...and that should remove all air pockets that are preventing proper flow.

Another thing to try is cracking the water pump bleeder screw located on, well, the water pump. It's the odd looking 12mm bolt--or maybe it’s 14mm? That will ensure that the water pump can move water and not air.

On a side note, you might want to change your engine oil seeing how the engine hit such radical temps.

hah, i just had the same problem not two days go. i needed to permatex my alternator cover because the stuff i used last time wouldn't keep it from leaking oil all over my boots. so i decided to do a oil and coolant change while i was at it. fill 'er up and go, right? wrong. i hit 117 C (for some reason my bike runs celcius) on the 12 mile ride to work. good news, no more oil leak! so i consulted my triumph buddies at work (and later my maintenance manual D'UH!). i noticed that it's helped alot to bleed the bike from the waterpump first. then remove the outboard hose from the water pump to get all of the fluid out of the system. you can run some fluid through it for an actual 'flush' but i think you'll be fine with just putting motorcycle antifreeze in. then, fill up the hose you removed from the water pump with fluid and reconnect it to the water pump. this will mean that the only air left in the lower part of the system is in the pump itself. if you have a buddy, lean the bike to the right and start filling from the radiator with the pump's bleed port cracked. you'll get a little bit of air and then fluid, let it flow for a while if you want and then close it off. tada, no air in the water pump. continue to fill the radiator. you can also bleed it from the crankcase bleed, but my screw was too long to take off without removing the hose too. it's located forward and above your alternator cover. again, same theory. once it looks like your radiator is full, rock the bike back and forth side to side to get all the air out, making the highest point the fill cap, this will remove the rest of the air. go for a little scoot, and you're done.

also, has anyone ran with 'Wetter Water'? I put the recomended amount in my bike and i can't really tell a difference. maybe 2 degrees C.
