    Radiator fan runs when engine is cold

    Excellent point. I don't know if any GMT800s came with e-fans. The supposition is if they did, then all GMT800s probably/or may have had the robust wiring/fuses/alternator to accommodate an e-fan upgrade. Again, I don't know...thoughts anyone???

    Radiator fan runs when engine is cold

    Replacing spark plug wires

    I have an '04 Suburban Z71 with 203K. Does it matter which spark plug wires to get with respect to the existing coils? I noticed that Rock Auto has many different spark plug wires for this vehicle and in some of them, in the description, it identifies the coil that it goes with (if that makes...

    Slick 50 Recharged

    I've heard that if your oil pan is painted that slick 50 will erode the paint and cause clogs. Does anyone know if my 2004 Suburban has such an oil pan? I few on-line forums seem to identify other smaller/compact cars but not big vehicles/v-8/etc. Does anyone know?
