Heater problem/ Thermostat? I have a 97 Z28 Camaro and my heater doesn't blow warm air at all. I have read that a coolant flush might solve the problem
but before I go through all that effort I thought I would get some opinions. The car runs around +-185F so I'm thinking the
P/O put a 160 T-stat in or removed it entirely. I just want a warm heater as its getting into the cold months of the year.
Should I buy a 180 T-Stat or flush the coolant?
Thanks

My '96 has a 160 thermostat and it blows warm air, definitely not very hot though. My former V6 Camaro had a plugged heater core from the DexCool turning to sludge in the system and had to replace the core. If your core is plugged, I doubt a flush will fix it.

1. the heater core is clogged.....pull off the two lines and flush water through it........
2. there is something wrong with the hot/cold control flap in the heater box.........this is what im betting..........
3. something wrong with the hot/cold changer on the dash
You more than likely have a clogged heater core. I can bring up the threads but I just had the same problem. The flush on shbox website gave me hot air for a day. So I finally got a replacement core and I have hot
Air for the 30 degree weather
btw I run a 160 stat tuned and the car never runs past 170 ish.
