1. My temperature gaugee (which is the combo fuel gauge, and lube oil
pressure gauge) is very speratic flipping around alot. I changed this whole
gauge unit out, same thing with the replacement,
Temp gauge bounces.
A) next step (????) change out sensor at engine. ??? I am going to try
this... is this the forward sensor or the after sensor on the left side of
engine block. Has any one done this job is it in a "thermo well" or when I
pull it does the sensor sit in the coolant and will leak. Any type of
sealant when I screw it back in please
B) Can start car and run from a cold start for 400 miles not problem. If
car comes to idle or if leave parked and shut off for a few minutes, and
reastart and get on highway
can only sometime experience over heating.
~~ If it is an air issue, can can air pocket in the thermostate housing and
cause it to "close" stop flow to radiator becuase the air is cooler than the
coolant??
~~Belts are tight to water pump, and when at highway speed not over heating
is experienced if started from cold
~~ could a small leak in the heater core (no steam or fog or liquid noticed
in car) cause the build up of air in system??
Please help thanks
