Radiator Fan Switch 900

posted by  someone claiming to be 93 wagonman on  Fri Jun 28 18:00 CST 2013 [RELATED]

Well my trusty non turbo 93 wagon needed a new radiator and I had my mechanic put it in. Apparently, however, he did not put in the radiator fan switch but left the plug in the radiator where the fan switch goes. He mentioned that he thought on the later 940 wagons the radiator fan switch wasn't used. I have heard something like this before but I am wondering just how hard is it to pull the plug out and install this switch? How easy is it to get the plug out and get the switch back in there>

Thanks

    Dear 93wagonman,

    Hope you're well. Your mechanic should have inferred from the temp sensor's presence, that it is a required part. Ergo, he should have removed the black plastic plug and replaced it with the temp sensor.

    Get a replacement rubber grommet from a Volvo dealer (#1378869, $4-5 MSRP). With the engine cold, grip the plastic plug with a vise grip pliers. You want to "walk" the plug out of the grommet. To do that, rock the vise grips gently from side-to-side (about 5 degress on either side of a straight line from the plug's center), while pulling backwards (towards the windshield).

    When the plug comes out, remove the grommet and - having lubricated the replacement grommet with dishwashing liquid - seat the new grommet in the radiator opening.

    Firmly press the temp sensor into the grommet. It will take some effort to do this. Once you've seated the temp sensor, use brass wire to secure the temp sensor. See the FAQs for the procedure. The wire will keep the temp sensor from coming loose.

    Hope this helps.

    Yours faithfully,

    Spook
