Hey guys,

I drove back to school from the mall today, stopped at the front of the building for a few minutes to let some people out, and then as I pulled away I heard a strange noise for a second from the front drivers side of the engine compartment. I didn't think anything of it and I drove the 1/8 mile to where I park, and got out and noticed wetness all around the drivers side front suspension and stuff, even on the mudflap. It was not water, and I determined it was coolant. I opened the coolant overfill reservoir and it was full to the brim and the little overflow hose had splash marks out of it.

I am not in the habit of overfilling my coolant system... any idea why so much coolant ejected out of the overflow tank?

thermostat stuck closed?

sounds like it started over heating could be a t-stat wich are very easy to change just make sure you get the dual staged ones from the dealer

I'd replace the Thermostat and the radiator cap. All the books will tell you to test them but they're so damn cheap just get new ones.

T-stat replacement is probably the easiest (besides the cap ) maintnence you'll ever do to a yota =)

Hmm, it never gave me a sign of overheating... And the t-stat is brand new! It is one with the little bypass valve as well.

The radiator cap, eh? Think it could be leaking?

buy a new cap

Also if the radiator cap dosent have a good seal or dosent close tight enough it might send fluid to the over flow. I have an 88 that has done that before...

if you lose a head gasket it will pressure the cooling system
