Subject: Re: Low coolant temps and no heat by BillH on 2008/11/27 16:49:52 OK, here's the correct shit. There is a "Heater flow Control Valve". It's a check valve in the inlet heater hose. It's located in the heater hose where it's clamped to the fenderwell about 8 inches from the heatercore nipple. It's interesting that after I posted about checking the heater hoses, I pulled the FSM. Under "Insufficient Heating", the diagniosis runs: Warm up to normal opp. temp. Temp lever to full hot, blower on high. Put hand close to lower hose, it should be hot. Put hand to lower hose, it should be cooler. Note that water always circulates thru the LT1 heater core. When the A/C is on the airflow goes thru the evap. and bypasses the heater core because the temperature mix door closes it off. |
