where is the senser that causes the car to run Rich????:(





also when replacing this senser do i have to take the coolant system apart??? bleed the system ???

[kenika65]

It is going to be your temp sensor #3 on your diagram, if you pop out the old sensor and pop the new sensor right in then you wont loose much coolant, but if your coolant is bad or old then deff replace, I allways bleed the system because it is good insurance and is fairly easy once you have done it.

but in your case you wont have to bleed the coolant because you wont loose much coolant and probably wont let any air in the system.
