Re: Heater Help

If the truck is AC equipped, make sure the compressor is not kicking in. Just pull the connector off the low side control switch (on the filter drier shell) - the compressor clutch is fed through that switch.

Re: Heater Help

Right now I have a sanden compressor, but i have not charged system/hooked up wires to it. Waiting until next spring. When I hooked up heatr core lines i hooked the bigger line coming of the LS water pump to the bigger opening of the heater core. I assume this is correct??
