Default Re: Thermostat change on 97 sl2

This can either one or two problems. If the original round nosed coolant sensor was never replaced, this faulty one can display incorrect temperatures as well as mess with fuel mixtures. The second problem is a worn out t-stat. Remove and examine the coolant sensor first unless it was already replaced - the flat nosed brass sensor corrects faulty sensor problems and a host of issues related to it. The t-stat is next if the temperature needle doesn't move to the 3/8ths position. A reader can help as it displays actual temperatures. Expect displayed temps between 185F-195F.

REWARD EXCELLENCE!
