i took the thermostat out of my 636 and boiled it in water. it sat in the boiling water for 5-10 minutes and never opened up, my ? is, does this for sure mean its bad. has anyone ever done this and actually seen there thermostat open in boiling water. i just dont want to replace it if i dont have to.

I feel you on this one. I've been having so many problems with my 636 overheating and spewing out fluid. I'm not sure what it is but I've tried many things. I'm thinking about replacing the thermostat but I haven't heard of them going bad.

just run it with out it. then you can see if that is your problem. if it stays cool then you need a new one

Here is what the manual says, so according to it the thermostat is bad

i ran it without on tues. night and it seems to be running better.

i didnt suspend mine, it says dont let it touch the sides or bottom of the pan and i let it do that, do you think that would affect it. mine didnt open at all with 10 mins. of boiling water

Compton82

Im not sure what suspending it actually does

NINER

Most of the time taking the thermostat out will cause the vehicle to overheat.

do what?..... your bike overheats when the t-stat stops the flow of coolant through the sytem, when you take it out there is nothing to regulate the flow of coolant so it runs wide open and your bike runs cooler...it wont hurt anything leaving it out but your bike will never run at optimum temp.

NINER

The thermostat also provdies a flow restriction in the open state. Taking it out eliminates the flow restriction that the cooling system is designed to have. I know it is counter-intuitive, but it is true.

solution to my problem: ordered a new thermostat, going to pick it up today

too many people have told me you need to run the thermostat, running without it at this time of year is fine, but when the weather warms up it could pose a problem. i just dont feel comfortable without it in

haha meant to click edit and clicked quote i guess

hahaha. Sorry just had to give ya **** man. Bike looks dope bro.

agreed, best thing to do

fyi (thermostat regulates the minimum operating temperature of the vehicle, therefore no thermostat means gonna take forever to get to operating temperature... in the winter it will suck but summer should be fine.) now the boiling water trick wont work... when your thermostat is in the bike it not only reacts to the heat but as the coolant gets hot it increases the pressure inside the cooling system which pushes the thermostat open.

im running without mine cause im cheap and i dont mind warming my bike up for 10 minutes at the lot before i start rippin. there is a noticeable difference stunting below operating temp so putting in a thermostat is the best thing to do.

yo D i got rid of my thermostat and used some anti freeze and that fixed my overheating problem.....What have you been told could happen not using it?
