    89 Goldwing overheating

    co-worker is having an overheating issue on his '89 Goldwing

    New Water pump and thermostat - dealer installed (25+ year Honda mechanic). Rad cap is the original - system was pressure tested.
    You can not smell antifreeze when the motor runs.
    There is an occasion puff of oil smoke when you start the bike after it sits for a few days.
    Starting the motor cold, the temp slowly rises to ¼ mark.10 to 15 min later temp will climb to ½ temp mark. Then it will climb to the red mark.
    Highway driving – temp needle is near the middle of the gauge.
    Using a temperature gun on the rads, it has been comfirmed that the temp gauge is in fact correctly reading the water temp
    Fans appeare to be working (blowing air), rads measure about 186 F at top and a couple of degrees lower at bottom.
    Does appear to take a slight amount of antifreeze.
     
    Any suggestions on what the problem might be? Real low compression?  Head gasket going south?

    What should he check next?

     if the smoke at startup is blue, it's oil. if it's white, it's anti freeze. could be a head gasket. or worse. have you cleaned out the radiator fins? sometimes they get clogged with road dirt and bugs.

    Fins are already clean - he is going to try the "hand over the exhaust" tonight to capture what is coming out on start-up - use the "feel" test on what he gets on his hands.

     anti freeze tastes/smells like artificial sweetener--be careful though, it's pretty poisonous

    Agreed - it isn't anything to be carless around

    get some oil or antrifreeze on the palm of your hand and you can generally run your fingers through it and tell the difference

    He couldn't get any film of any kind when he started it - he is getting pretty discusted - it is a couple of hours work just to remove the "tupperwear" to get anywhere near the engine  ">">

    I wouldn't be supprosed if he turns around and sells it for junk ">

    Re: 89 Goldwing overheating

    There should be a siphon tube going to the reserve tank for the coolant. When the heat goes up the radiator caps pressure valve lets some of the hot coolant to go into that reserve tank. Check for cracks on that siphon tube and reserve tank. The seal could be bad to the tank. Being how it is a older model that may be your problem. If it isnt sealed properly when the coolant cools instead of pulling the coolant out of the reserve tank it will just pull air. This wasnt an uncommon problem for 1500 Goldies so hopefully this helps

    Re: 89 Goldwing overheating

    thanks Paul - he is going to check that this weekend when he pulls the "tupperwear" off (2 hour job).  He is also going to check if there is a possibility of an airlock in the cooling system.

    Re: 89 Goldwing overheating

    Update:

    he agreed to have the dealer (only one who would work on it) pull the heads looking for a bad head gasket - nothing obvious other than one of the rad connector pipes has a small kink (not enough to fully block the rad). 

    He took the rads home to give them a flush with CLR and low and behold the left rad seems to be about half blocked - he can't tell if there is any significant blockage in the right one.

    Re: 89 Goldwing overheating

    another update - the dealer put the bike back together - new head gaskets and a couple of hoses and the old rads - no change

    He has a couple of used "supposedly good" rads coming - time will tell

    Re: 89 Goldwing overheating

    and yet another update 

    a Used left side rad was installed and the results are:
    - tempature stays normal on the highway (this wasn't a problem)
    - tempature stays normal on city driving other than stop & go (this was running warm but within specs)
    - tempature rises to at least 3/4 - sometimes to the red - but quickly returns to normal when moving again

    It appears the first thought about a rad issue was the problem - the owner is searching for a right -side rad to help with the stop & go.
