my87manche

i'm about 3/4 done with my a/c install. pulled everything from a '94 chero. they are R134A systems. E-fan is the easy part, the mounting tabs are already un the rad. for a fact. fan, just use an toggle switch & relay. if you can,get the whole wiring harness for a renix w/AC. it will be much easier than making one as i am. i'm looking for a harness myself.

check EGR. nox caused by excessive combustion temps. EGR sends exhaust gases in to lower temps and nox.

2002 will use R134A, if someone put R12 in it then drain all the oil you can and use ester oil then charge with 134. the hoses,condenser & evaporator are different for R134A. more fins per sq.in. &barrier hoses. i am currently beginning to put a/c in my '87. also there are relays that are controlled by the PCM for comp. clutch,fan control & idle speed which i have to find out if the renix control module is the same between A/C & non A/C trucks.
