1988 560SL, TRQ
Can anyone help me identify this part on the front left just behind the grill. Looks ceramic and is crumbling.
Thanks.Can't speak to what effect it would have but here's a post from a couple of weeks ago listing a couple of sources for replacement. Guess they are not easy to find.
87 560SL Aux cooling fan resistor?
ps...If you have access to a salvage yard the MB 560 SEL's and SEC's use the same resistor. Of course they may not be in any better shape than yours...
it affects the low-speed stage of the cooling fan. the fan kicks in at low speed when AC is running and condenser temp rises.With this thing in crumbles could it effect the function of the cooling fan?
Thanks. Based on the PN on it is the Aux Cooling Resistor.it affects the low-speed stage of the cooling fan. the fan kicks in at low speed when AC is running and condenser temp rises.
if you couldn't find any good replacement, you can just bypass it with a jumper wire, that way the fan will kick in at normal high speed with AC on. I did that myself with my w124 in order to improve my AC Efficiency after the r134 conversion and it did improve a lot when the car is steady and not moving fast in traffic.
BUT please make sure that it is really the fan resistor and not the ballast resistor for the ignition circuit, I don't have any experience with your car ignition system and don't know if it has a such ballast resistor or not. both are very identical in form and shape.
