I checked my coolant level today for the concern that my temperature gauge has been going screwy. one guy told me to make sure the coolant is at the top of were you check it. well it wasnt. when i pulled the stick out the bottom of it was rather dirty, brown kind of. I havent done anything yet because I want to know if this is normal and the proper place to put coolant in. and if in fact it needs to rest at the top of that.

 

I bought prediluted coolant.

 

The wiring leading from those two sensors in the middle seemed to be fine. if this coolant doesnt fix the gauge I will post again, but my main concern is what i stated above.

 

thanks so much!! Jordan

You want to be looking in the rad not the expansion tank mate, coolant should be up to the top.

Also, if your coolant is a brown rusty colour then you should flush it out and put fresh in.
