vintage air and overheating issue (LS engine)
hi, I have '86 C10 swb with '13 5.3 gen iv DOD delete LS factory ecm and wiring harness, I installed a gen iv fact. replacement VA A.C. system. my problem is the engine gets too hot with the HCV closed. talking with V.A. and installed the "sometimes recommended" H-PIPE (recommended on "some LS and coyote engines). I am wondering if anyone else had to install a "H-pipe" to adjust for the HCV when closed?
