Could someone please clear up the difference between these 2 aux switches?
I have the Aux coolant fan switch in my car which I THOUGHT cooled my turbos for over 2 years now. Another member asked me what the differnece is between the two on ECS's site that I linked (both are blue) Can someone fill me in?
Have I been strictly spinning my fan on shutoff and not actually cooling my turbos? FYI, I bought the $20 one.<ul><li><a href="http://www.ecstuning.com/stage/edpd/pagebuild_v2.cgi?make=Audi&engine=2.7T&mod el=B5%20S4&submodel=&category=Engine&s ubcategory=Cooling">http://www.ecstuning.com/stage/edpd/pagebuild_v2.cgi?make=Audi&engine=2.7

The fan switch goes in the rad and controls the fan. The afterrun aux pump....
switch is what controls the after-run coolant pump located under the intake mani. This switch is on the coolant pipe under the coolant reservoir. The coolant temp sensor does a variety of things, and is on the coolant pipe under the MAF.
