over heating and stupid red light ):

plebpl · Guru

did you check your head for warp?

edgie432 · DTR Member

ye its fine just dont know how to stop it over heating

Moved to Tuning section, please keep engine threads out of the GENERAL chat section, cheers

Also check that your rad is working properly, if your head isnt warped and no leaks, sounds like a rad problem. Not sure about sensors tbh

no leaks had a idea that it cud be the rad cap not holdin pressure so water eveporates but dno no leaks but it is spitting alot out of the drain off pipe down by the foot peg ? wat cud make it do that ?

Seiki · Admin

Sounds like the rad is packing up man, all tubes clear etc?

richie · DTR Respected Member

same thing happened to me today engine now seized be careful its either rad, head , oil pump

ToySoldier · DTR Legend

what head gasket did you use allways use proppa yammy ones mine used to boil and overheat cos it had a crappy patern white gasket

edgie432 · DTR Member

the gasket kit i got is from a genuin yammy dealer, the head is fine so its either the rad or the oil pump, i was told removing the thermostat with allow a constant flow of water so it wont overheat AS MUCH ? i will try this to see if it resolves the problem for now untill i can get a pemenant fix

aslong as theres plenty of anti freeze in the cooling system it cant seize if i keep toppn it up now and again the water is evaporating from the rad cap and its also pouring out of the overflow pipe ?

How u riding it? gentle or not?
I had a dtr that riding gentle would make it OH, You need give it some stick every now and then for rat to get cool from the air.

if i wer you m8 id get the head skimmed jus to be 110% sure, check the rad isnt blocked by disconnecting both pipes n whack a hose pipe in there check the water flows through freely, try taking the thermostat out completely n run it without one, and check that the water pump is ok , impeller blades and drive gear on the back,

big give away that the head is warped no matter how many head gaskets u replace if the head is warped then it will continue to blow coolant out of the expansion bottle

dont mean to steal anyones thunder, but check this section for my thread called coolant issues. ive got the same problem and a garage or myself cant sort it. so have a read of the suggestions.

Check off two pipe plug ñ RAD hammer in check the free flow of water through the hose pipe, try to run the thermostat no one completely..
