My friend just got his raptor bored to a 686 well we changed the coolent to watter wetter and put fin coolers in. and when we started it it ran for a while then died, well we changed the spark plug and it would try to turn over just no start. well we took off the header and there is alot of coolent in it . HOW DID THAT GET THERE. what caused it please help guys

 

maybe wrong coolant and wrong coolers..

 

retorque the head bolts, twisted up line from the radiator or you have a bad radiator cap...

did the fluid go into the head or the header (Pipes)?

 

wazz up Raptor 03 It's me!!!

 

I dont know we havent took of the head yet but there was a good amount in the header

 

I dont know about ATVs... but if there is coolant in there on cars, the head gasket is gone.
