You'll have to buy a service manual from the parts store. It'll show you each step and give you other good information. I just changed my heater core in my 94 Grand Am Quad 4 and it was a pain. Good Luck.
how to changing engine coolant on a 1993 mercury grand marquis gs.
If there is a block heater installed then there should be a plug at the hood/lights or bottom of engine.
In most cases a block heater replaces one of t he freeze plugs in the engine
The heater would not be working on a 1990 Dodge Grand Caravan if the heater core is damaged or blocked. Hot coolant from the engine must flow through the core to allow hot air to pass into the cabin.
Yes, there is a difference between changing the alternator in a 2.3L grand am than there would be in a 2.4L grand am, because it needs a more powerful alternator to turn over the engine
Check to insure that the engine coolant is full and the thermostat is not stuck. Without the heated fluid from the engine the heater will always blow cold air.
Changing the heater core requires complete removal of the dash panel and plenum box. To do this you have to remove the steering wheel, steering column, evacuate and recharge the refrigerant system and drain the radiator. I would only consider changing the heater core if it is physically leaking into the passenger compartment. If the problem is heat transfer to the HVAC system only, the problem is more likely with the blend doors. Check heatertreater.net for pictures and diagnostic information.

It goes into the water pump. You remove a plug and screw in the block heater. Between the engine and the firewall. You can get at it from underneath.
