01 LT overheating

Just got back from a weekend trip and encountered overheating. I have read a couple other threads here about this and want to get opinions.
It's not that the gauge goes all the way up, but the warning light comes on if stopped for a little while. Moving above 30 mph the light goes off after a minute or two. Some times the gauge was only around half way. Both fans run and the coolant level in the tank is fine.
I am thinking either thermostat or water pump.
Any ideas?

Thanks,
Scott

Re: 01 LT overheating

You may have an air bubble in the system. I would suspect the T-stat before the water pump. Especially since the gauge did not go full scale.

Re: 01 LT overheating

Tonight took the body work off and found green residue by the left fan and a little on the side of the radiator. Removed the cap and see that the coolant is low.
Does anyone know if the radiators can be fixed? Or should I look on Ebay for another?
Or should I just fill the radiator and hope it last the rest of the summer?

Sounds like you possibly have a bad radiator cap. I would try that before replacing radiators. BTW BMW coolant is blue.

Re: 01 LT overheating

agree with Robert, the new prestone coolant is YELLOW but appears greenish to me and it is OK to use - it is also possible it has the old green coolant but it has not been around for quite some time

Re: 01 LT overheating

So, the symptoms are that the fans come on with the light, but the temp gauge doesn't show hot....Right? Had the exact same problem, did a search on the site and discovered another person with the same problem....Here is the deal, there are 2 thermostats on the LT, one in the water pump area, that controls the gauge on your dash, the other is located on the back end of the head, that one sends messages to your computer which controls the cooling fans and the idiot light.....The solution is to replace the thermostat on the head, a $70 dollar part, and viola problem solved....Check it out. If the bike was actually over heating, the gauge on the dash would be in the red as well.

Those two parts are not thermostats. They are temperature sending units. The LT has only one thermostat.

Re: 01 LT overheating

Update:
Got a new cap, filled with new coolant, and started it to see if it works. Well it did to an extent. At first everything seemed fine, the fans did not come on until the gauge was about 3/4, but it looks like the left radiator is leaking at the seam where the plastic top meets the metal core.
Just ordered a replacement on Ebay.

Yea you betcha! OOPS! you got me now....either way when the sender on the head malfunctions, it gives the symptoms of fans on early and temp light lighting, but the gauge tell you if the bike is overheating, if the gauge doesn't indicate overheating, it is the head temp sender....temp sender....temp sender...ok, I got it now...

Re: 01 LT overheating

Ok, this poses a question. Since I've done an engine swap I've noticed that my right fan comes on about two needle widths on the gauge above the center mark. Maybe the other one comes on too, just can't hear it. I read on another post that it is only 15 degrees from that mark and the red line. Is this something to be concerned about? Or do I need to correct it now?
