To Remove Radiator Thermostat

hello there,

Anyone tried to remove the radiator thermostat? Direct coolant will effect the engine performance?

You mean take it out and short cut it, so the fan works as the engine starts?
I never tried it, as it also will cause unnecessary fan work.
We know that to certain degree of heat the engine just need natural cooling. So we may extend the fan's age.

no...im talking about the thermostat... "Device that opens or closes a circuit in response to changes in temperature"

the coolant liquid will always flow into the engine block 24/7

Misconception again. :shock: :shock:

To many people, a thermostat flows water INTO the block/ head. That's not the case.

A thermostat actually PREVENTS water in the head from coming out (flowing into the radiator) until the temp it was designed to be opened.

Removing a thermostat flows water without obstruction. It spells without PRESSURE. Without proper pressure in the head, water tends to boil under hot temp. While water that's with a pressure boils at a higher temp, thus reducing the tendency to boil.

So the head without themostat will boil and steam pocket will appear. When they appears, no water will reach the specific area because of the steam. That area is k nown as the hot spot. It will overheat. Blows head gaskets, detonates, and in worst case, softens the head and wreck an engine.

Cheers

some cases happen the thermostat not working as normal..and the engine will blow also...any comment?

the do we have MECHANICAL thermostat in t135?

the thermostat we have in our bike is just a temperatur switch to turn on the fan if it gets high temp, right?

Not that bro. The thermostat is the in the head. Its a mechanical spring loaded device that opens up when its heated to the specific temp its designed for.

Seldom fail. The workshop manual has got detail explanation how to check it.

actually I already have take out the thermostat before i posted this topic...will get a picture of the thermostat...so that we can share.....im afraid the part that i have take out is a different thing... many thanks :?

For people who live in very hot communities (eg. the desert), it may be OK to remove the thermostat entirely. There is no advantage in doing this unless you have had consistent problems with thermostats getting stuck in the closed position, in which case it may be acceptable to remove the thermostat. Again, this only applies to very hot communities and in particular, during summer months.

i have done this modification in my car, but not yet on my 135lc. when i remove my thermostat its just making the coolant free flowing from the radiator line going to engine specially when my engine is running. and the radiator fan is not always turning on due to the temperature of my engine is not getting too hot. so the advantage of doing this is to make our engine maintained its normal temperature in longer time before it will turn on the radiator fan when it reached it high temperature.

interesting topic,,,,,if we do to remove the thermostat in our lc135 what will happen?
what the performance we get of our engine?

I hope this help. Once in my oil change at yamaha 3shop. I ask the mechanic about the concept behind that radiator thermostat. He said once the overheat indicator turns red. the Radiator thermostat open and will circulate the hot coolant from the block to the radiator and then the fan will turn on.

longer period of normal temperature and it will reduce the consumption of electricity which is being consumed by the fan and thermostat switch.

ur right sir. thats why if you remove the thermostat inside the line, the coolant will flow freely before it reach it setting temperature because you remove the thermostat or we could call like a gate, which hinders the coolant from free flowing. so if you have free flowing coolant in the line it will be longer time before it operates the fan.

Since i modified my lc135 i removed the thermostat..,bcoz my brt hyperband is always sending signal to activate my radiator fan. At 60 degrees celcius the fan is activating to my brt hyperband (the old model brt). then i decided to remove the thermostat., the thing with a spring bolted to the head. Wow! I noticed that my radiator fan is not always rotating, my machine is colder than before having a thermostat.., the coolant is free flowing now.
