GUYS I NEED HELP
MY A6 4.2 OVERHEATING
WATER TEMP IS ON "H" AND COMPUTER ASKING ME TO CHECK COOLANT LEVEL
WITCH IS FINE
OIL TEMP. IS FINE <250
i NOTICED THAT 2 SMALLER FUNS ON THE RADIATOR DOE'SN'T WORK!!!!!!!!!!
when are they supouse to kick in??
some kind of thermo switch???
( sorry I'm guessing)
coolant reservoir and radiator are hot so I think thermostat and wather pump are fine too!!!

what do U think
is ther any fuse controling this 2 fans on the radiator?




THX!!!!!!!!!!1

 

Maybe a bad coolant level sensor. Why the fan is not turning on? Bad relay, fuse.

Yeah if so where is it located
nothink in fuse panel- just checked!!!!!!!!!!
I need to fix it asap
98F to day in chicago!!!!!!!!!!!

 

The fuse for the electric fan on my 1998 A6 is located behind a trim panel beneath the steering column (behind the dash). Hope that helps.

 

There is a TSB at audi for the fan control module having wiring problems, the fix is installing an overlay harness. Take it to the dealer and tell them both of your fans aren't working. Im not sure if it applies to the 4.2L engine but thats what it sounds like.

 

any other ideas??

 

How did you make out? My temp guage was at 4/5ths today, constant on highway and local stop and go, and no change when i turned on AC (which should activate aux fan, I assume). So I'm thinking sending unit, but...

 

Your thermostat is like stuck closed. It blocks the coolant flow and the fans don't come on because the heated coolant dosn't reach the fan switch. The over heat light looks very similar to the low coolant light.

 

MY 2000 AUDI A6 2.7T IS OVERHEATING ,COOLANT LEVEL IS GOOD ,I DONT THINK THE FAN IS WORKING PLEASE HELP ME.WHAT DO I HAVE TO DO TO FIX THE FAN
