fan removal/installation

Post by quasi2008 » Sun Apr 14, 2019 10:13 pm



is it necessary to remove the radiator to swap out the fan assy? I worked in automotive collision for over 30 years and this radiator is the worst I've ever dealt with to burp and i'd just rather not remove it if I don't really have to. tks,

I figured as much. never hurts to ask though, huh. do you have a secret trick to burping these things. I've constantly got coolant being pushed out until air is gone. never had so much problem burping a radiator. thanks,

The way I do it is to fill the radiator to

the top. Let it sit over night, fill some more if needed.
Then I fill the reservoir to the upper level, cap the radiator, then run the engine while checking for leaks.
Let the engine run till the fan kicks in and let the fan cycle on and off about 3 times, then stop the engine and let it sit.
The pressure build up in the cooling system will push out what ever air is left to the reservoir and as it cools it will vacuum in fluid from the reservoir.
Once cool check coolant level at reservoir and fill as needed.

The radiator is not a problem to burp, the problem to burp the system is if the original thermostat has the burp hole plugged or installed upside down, or the original thermostat has been replaced by a aftermarket one and the little burp hole jiggler thingy of sorts was not removed. The original thermostat does not have a jiggler thingy.
Also having the bike on the center stand helps a bit.

Oh yea forgot to mention this one came out of my gl1200. Figure they use the same thermostat.
At any rate the burp hole should be a 12 o'clock with no obstruction.
Some aftermarket ones do not have the burp hole, some do and some have that little thingy on the hole.
I removed the thingy and drilled the burp hole as close in size to the original thermostat burp hole.

while i had the radiator out to replace the generic camshaft seals with OEM ones, I pulled the tstat housing and lo and behold, the hole was at the 6 oclock position. also had the little jiggle thingy which I removed. tstat is now installed properly, hole at 12 oclock. coolant in the system sitting til morning. tks for the info.
