Hi Dennis, When the AC is selected an additional cooling fan should cut in to cool the additional requirements of the condenser radiator, mounted in front of the radiator cooling the engine. If the operation of the AC fan is intermittent the most probable cause is a defective control relay or a loose connection. The relays are easy to find, being in a housing usually marked on top of the outside. Regards John

SOURCE: 92 lexus es300 knock sensor

Need to remove the upper and lower air intake manifold.  There are two knock sensors for the front and rear pistons banks.  If you plan to do this yourself it is about 1 to 2 hours.  While you are at it, there is a short coolant bypass hose sitting in the same spot, replace it.  Another problem with the knock sensor is the wire harness used to connect the two knock sensors into one connection sometimes wears out and contacts the metal on the engine causing false signals to the ECM, so replace this cable also.
Just did this last summer on my 99 ES300.  Pretty easy.

SOURCE: AC Belt squeaks on my 2002 Lexus es300

When belts squeak it's either from dryness wear or tension / tightness / looseness affecting alignment.

Check for tightness and you can spray with belt dressing and try some WD40 on the compressor pulley.

If none of that doesn't stop it it very well could be the clutch or pulley is stiff from non use and could need replacing soon.

Fan kicks on at what temp.?


most thermostats start to open at 85 decrees c so the fans should start at that setting . Check with your workshop manual or ask a dealer service centre for the exact setting as it is critical as to when they open for cooling the coolant temperature.
