[V8] Temp. Sensor & 02 Sensor

[Campozano, Robert]

I am horrible at describing things so, Tony Hoffman, can you help out
here?  My car had the same exact symptoms and Tony found that the
fusible link that connects to the auxiliary fan had blown.  It's an 8
dollar part at the dealer and it's connected in a small little box right
in front of the Power steering reservoir tank with 2 screws...sorry,
best description I can give.  My car has not overheated once since
install.

 

Also, in regards to all of the 02 sensor calls, my cars mileage has
increased about 5-6 miles a gallon, no longer surges, and no big grey
puffs of smoke out the exhaust after Tony installed the 02 sensor in the
vehicle and grounded it to the strut tower.

 

Hope this helps...

Check your fan clutch. I never hear this suggested,yet is almost alway
the culprit with the symptoms your having. I know it was in my case.
