If you do end up replacing that blue Temp 2 sensor please be sure you have
the proper o ring to go on the new sensor. The first time I did this I
bought sokme generic ones from my Flapps - well they didn't seal well at all
and I lost more coolant thatn I wanted too while I removed the old one from
the old sensor. Didn't really hurt anything but it made a mess and I had to
"burp" the system.
