Re: My New 03 1500HD

2 updates!

Ever since I installed the electric fans I have had an A/C issue that hasn't been a problem until recently. The problem is that on Max A/C the truck blows warm air through the vents because the second fan doesn't kick on. This hasn't been a problem until now because I don't usually run the A/C in town, I just cruse with the windows cracked, and when I do run it I am at speed down the highway where there is enough air running through the rad that the fans aren't on. The second fan does kick on when it needs the extra flow when sitting in traffic and the engine is real hot, but not when the A/C is cranked. So, I went back to the mechanical fan set up I kept because with a new child I definitely want to keep both him and the wife from screaming at me because it is so hot sitting in traffic.

I have noticed a little less off the line power, but everything else seems the same...except the Hydro Boost brakes seem to be more firm now and when coming to a stop the the rpms drop below 500 for about 1-2 seconds and pick back up. Go figure!

The other thing I did was get sick of the Bow-tie o the grill of my truck falling off so like a new Camaro Z/28 I grabbed a die grinder and cut out the emblem leaving the negative space behind as a black back drop. Glancing at it it just looks like black emblem.
