Hello
My thermostat is fluctuating between 105 an 210 an finally stays on 105 an i am having to add coolant every now an then can't find no leaks

 

the fluctuation is prop because of low coolant. have you had the coolant tested for exhaust gasses?

 

I have no coolant coming out exhaust it's clean coolant is going some where water pump is clean dipstick is clean too.she don't try torun hot.

 

U think i should change out the water pump to b safe an thermostat too.

 

What year is your Express, and how many miles are on it?

moved your post to the appropriate spot. well it has to be leaking somewhere, park over a dry spot/clean area (if you cant find one put a piece of cardboard under the truck and let it idle to see if leaks any

 

Ok thx for the info
