[W126 Coupe] The Temperature! (and other stuff)

[Iain Gunn]

First I used Wagner Thermo Quite pads on the rear with the red high temp Permatex, still quite. They came chamfered and cut, recommended by my parts guy, very reasonably priced. Wagner didn't recommend anything be put on the pads, but they groaned and squealed, but not after the Permatex. Thin layer, put on immediately.
    Second, my viscous fan on my 560 SEL is getting very noisy, What fan did you put on. Also from other listers, I've read that they put a flex fan on?? Make, price, was it a straight fit??
                                                                                        Thanks, Iain
P.S. Sold the 86 560 SEC Koenig widebody on the weekend.

  OK, I abused several folks last winter when it was -22 degrees and blizzard conditions in the northeast. Now it's your turn. It's still officially Spring here in Las Vegas and we got to 105 degrees today. It's the third day in a row for 100+ readings and we have maybe three days more of 100+ readings. Today was great for me though, I worked at home and never left the air conditioning. I did verify that the new a/c duct I had run into the garage made a difference though - with an insulated garage door and the a/c vent only partially open, it did get to 90 in there, fifteen degrees below the outside air.

   

  I put a new standard fan clutch on the SEC a couple of weeks ago and it is now running noticeably cooler than the SEL with a stock (original) clutch. Looks like I'll be ordering a clutch for the SEL shortly.

   

  The NoiseFree brake compound I tried on the SEC rear brakes isn't much better than the Permatex or CRC anti-squeal compound. I bought a set of PBR semi-metallic rear brake pads for the SEC and they squealed like mad on there. I put on a thin coat of Permatex on the pads and shims, then a thicker coat on the pads and shims, then took off the shims and put on a fairly thick coat of Permatex, but it was still noisy. I tried the orange CRC anti-squeal compound with and without shims, but no change. I heard about NoiseFree, that it was "industrial strength" anti-squeal, but it was not much better and the brakes are still noisy. The NoiseFree guy said that the lip on the outside of the rear rotors was a part of the problem, then said the ridge on the inside was part of the problem after I told him that I had ground off the outer lip and put on a nice layer his compound to no avail.

   

  Rusty didn't refund the cost of the PBR pads when I purchased a set of Pagid pads, new rear rotors, and new parking brake parts. Not much to like there either. 

   

  Later,
