83 interstate over heating

Post by rodburner6011 »



I bought an 83 and found out it has an overheating problem. I've had the radiator cleaned, new coolent, water pump checked and works fine, thermostat new and good, I put the fan on a toggle switch and it works good. No leeks that I can see. Not in gear it is fine. Going down the road it gets super hot, no matter what gear. I can pull the clutch and coast, or stop, and it will cool down quickly. Last time out I had to do this for 35 miles to get it home.(no fun) However it did not heat up on the trip to where I was going. Don't really want to sell it to some unsuspecting rider. Would appreciate any suggestions.
Thanks

Do you have any history on the bike?

Has it just started overheating? IS there oil in the coolant or vice versa?

Does it blow any smoke?

Does it build up a lot of pressure in the radiator. Does the overflow bottle boil?

Just looking for symptoms really.

Check radiator cap - if not holding pressure coolant will boil into recovery tank even before getting hot, then radiator is low, engine overheats. When it starts to cool down sucks the coolant from recovery tank back into the radiator and you are good to go again (for a while)

Have you burped the system to get all the air out and are all the hoses good to the overflow tank? Did you install the thermostat and is it a Honda thermostat? A Honda thermostat is the way to go, yes you can use the Napa but it isn't right. How about the radiator hoses, good condition and not separated inside the hose or cracked and hard as a rock? Yep radiator cap for sure could bad for sure. No short cuts on the cooling system. You didn't state if you happened to pull the inlet cover of the water pump and inspect the pump impellers or any shaft movement. I am sure you did.Let us know what you find.

my problem with overheating turned out to be right side head gasket. i went through 2 head gaskets before i ended up switching heads from another doner bike.
as said use ONLY Honda gaskets.
my tell tail sign was right front spark plug would foul . when bike would sit after a ride radiator fluid would run into cylinder . pretty much missed the summer riding.
good luck.
