I'm trying to pin-point which coolant temperature sensor is the B11/2 on my '86 560SL, and from your advice above, I found the picture on page 204 of my trouble shooting manual. Thanks much. Agree the captions appear contradictory. I think this is the one at the rear right of the engine, driver's seat perspective?
Since I may need to order a new one, I'll await your test results, which I'll try to duplicate to confirm if I need one. Sure would appreciate a simple description of how to do the test with a multimeter, or whatever, for us less expert DIYer's.
Meantime, to get pricing on new, could you tell me what the Fastlane part number is? It seems like there are 3 coolant/temperature sensors: B11/2, B13, and S25/5. The picture of B11/2 is dark, can't tell what the contact looks like.
I think the B13 and S25/5 are at the front by the ISAV, and this puppy is at the rear of the engine?
(BTW, car is in storage now, so I can't readily pop the hood and look for myself. I'd like to be prepared though for spring...if it ever arrives!)
Would one of these be the one?
