Engine running hot.

Post by cgoins » Fri Jul 01, 2011 9:59 pm

I bought my 87 Interstate 4 months ago and moved to Tucson. I flushed and changed the fluids including the coolant. It's still runs hot and almost runs in the red zone. What can I do?

Is your cooling fan coming on? I just bought an 87 as wall in May and found pretty quick the thermoswitch was not working. Followed a tip I read and installed a toggle switch so I can turn it on when needed. I'll be replacing the thermoswitch in my long Alaska winter.

Is any coolant coming out of the water pump weep hole, if not then I would start with the thermostat first.

I would check the before mentioned solutions first as they are the most likely but if you bought the bike used the previous owner might have played with the jets to lean the bike out a bit. This would make the bike run a bit hot and if is getting out of tune and leaning up further then hot would be the word of the day. Just a thought if the other solutions don't pan out. Good luck.

You changed the coolant. HAs the cooling system been "burped". I've seen it before where air in the cooling system causes overheating.
