The heater core resembles a small radiator.
The heater coil is located behind the dash board. You will have to remove the dashboard to get at the heater coil
That is the ignition coil.
The coil is attached to the top of the distributor cap.
no
yes it can. If your heater core is leaking it will leak on the passenger side floor in the cab of the truck or car.
the HEATER CORE can be removed by removing the dash. how do i ghange the dash
what is the coil firing order on a 1998 chevy venture van with a 3400 engine?
Depends, Is it blowing air at all? If not then could be the fan, fan motor, or an electrical problem possibly with the heater controls. If it is just blowing cold then your going to want to check the heater coil, on that truck I believe it is on the passenger side under dash/floorboard. you may smell anti-freeze if so the heater coil is the problem.
It is in the lower line coming out of the condenser coil. Remove right side (passenger side) turn signal . It's located behind the light.
Heater CORE, not coil. The core is plugged and needs back flushing or replacement.
it is next to the firewall near the heater coil
Does it have fuel, spark (BAD COIL?) and compression?
