replacing thermostat

Post by aj1500 »



I let my 1500 overheat ( had a senior moment) and the little plastic TEE down near the thermostat cracked and is leaking coolant, I decided since it ran hot I would replace the thermostat while I am replacing the TEE and hoses. I have it torn down now to where I have removed both fans, I have both radiators loose and folded forward out of the way but not removed. I can see the thermostat housing, I think I can get in there to replace it but just watched a vid about it and they had removed the carbs and went from the top. I see I will have to remove the fill tube or at least take it loose as it looks like it is the hose on top of the thermostat.
So here is the real question, can I just take the fill tube loose, raise the hose off the thermostat housing and replace the stat or do I really need to pull the carbs and go in from the top

I've done this nasty job once, and I went in from the top. That's not to say that it can't be done the way you're thinking - it's been long enough that I don't recall if there is anything blocking what you're considering. Might be worth a try?

I did the thermostat at the same time that I was chasing a coolant leak. And it was a pain even with the carbs off and the radiators removed. I would think that trying to get at the t stat housing bolts would be quite a challenge with only the radiators removed.

I must say, it's often tempting to take a short cut to try to remove something without pulling other stuff off to give access - but I find that often you end up spending more time doing that than if you had taken the time to pull everything apart in the first place.

yeah I was afraid it was going to come to that, not really looking for short cuts so much as not knowing the best way to get where I needed to be. I got fairly good at pulling and reinstalling the carbs working on my wife's trike so I guess if that is the best way then so be it. haven't had a chance to get back to it, got sick last week and still fighting through it now. I'll post back once I get in there and get it done. who knows I may find a trick or 2 I can share
Thanks for the reply's everyone

Would love to hear if you find any tricks to make that job go any better. Get well first. It’s not fun doing anything when you’re sick.
