#1 Did you fill up coolant directly into radiator or let it fill from overflow bottle? The only way is to fill up the radiator.

# 2 is your radiator finns clean? It is have to transfer heat with bugs and dirt on the finns.



#3 always check that you have enough coolant in radiator. 50/50 water and dex-cool anti-freeze. It is orange and made for aluminum radiators[low selicate]

Hey your location is not on your profile and do you have a 1200 or 1100.Helps us allot in our answers.

I had to take off my radiator recently. If the radiator doesn't get filled all the way, the thermo fan switch won't turn on the fan and the bike will overheat.

He has an 1100 as indicated in the original post.

GL1100, that one is old, it may be time to remove the radiator and have it rodded-out. Meaning the radiator shop removes the top, pushes a rod down through the cores to remove sediment, then reassemble it. Or buy a new radiator. This may run between $60.00 to I am guessing now, $150.00. I had my car radiator done for $65.00 in San Angelo TX, two years ago. It purging the air does not get it, it is clogged up. Sorry, Ole Guy

:waving:Low silicate? What you want is a silicate free antifreeze such as the Honda Type 2 coolantthat you can get from your local Honda auto dealer. It comes in gallon quantities and is prediluted ready to use. This is cheaper than buying it from your local bike shop that only sells it in quarts. Using an antifreeze with silicates will eventually damage your water pump seals.

Lots of good info on site on this issue. You can do a search.



A few things to check ie: rad/waterpump/thermoswitch. You'll have to give some more info as to if fan comes on etc.
