Over heating on 1984 1200 Aspy

Post by Peeler » Sat Mar 05, 2016 5:31 pm

Is there a way to tell if the water is circulating? I heard that the reservoir can be full but no water is getting to the motor.
After changing timing belts refilling the reservoir mine seemed to run hot and anti freeze was coming from somewhere.
I did tighten all clamps.
Could there be a bubble in the system? And how to bleed it out?

You need to fill the radiator, take the cap off and fill from there. A coolant leak could make it over heat, cause the radiator isnt building up enough pressure, which raises the boiling point. A bubble is possible. On cars you can remove the radiator cap and squeeze the lower radiator hose lots of times to work the bubbles out. Wing same principle. DO NOT REMOVE RADIATOR CAP WHILE ENGINE IS HOT!!

Have a look at How to flush your cooling system. It shows the correct procedure for removing air from the cooling system - it is shown on the GL1100, but the procedure is exactly the same on the GL1200.

You should never see coolant leaking out anywhere, obviously.
