Unless your coolant has spilled into the driver/passenger compartment first you must drain the coolant out of the hoses and then you must remove the shifter console. Directly behind the console just below the radio you should see a square shape plastic box which contains the heater core you must open the box by unscrewing or unsnapping the fasteners. (Be patient. It's going to get a little tight but you can do it without having to remove the entire dash.)
Pay attention to how it's set up inside the box and just disconnect the old unit and replace it with the new, remember to retrace you steps when putting it all back together, it should take you about 1-2 hrs.
Don't forget refill your coolant and in most cases you have to have your A/C unit recharged after doing a heater core replacement.
Call your local auto-parts store and verify the A/C unit having to be recharged only if your vehicle comes with an A/C unit installed.

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 it should bolt right up as well as the original motor and tranny
clean out or replace the throttle body spacer...
how do i change the heater core in a 1990 Eddie Bauer
Pretty difficult you will more than likely take have to take the whole dash out... It will be an all day job

i have a 2003 Pontiac grand am, no start, does not even turn over. could it be the ignition switch?
If it is anything like my 93, your heater hoses run from the heatercore through your firewall. Mine is located in the center most are located on the passenger side. Pop your hood look at your firewall you should see two hoses relatively close together coming out of it, those should be your heater hoses, and they are a pain. I'm trying to get them on the new heater core now...
I am not an expert on the 1990 Grand Prix but on a GM product I would look for a round flasher assembly located near the fusebox downunder on the left side of the dash.
This information should be on the fan shroud.
It is a very involved procedure. Get a manual on your car from the parts store or from AUTOREPAIR2000.COM
Mrkhh. I stand corrected. The firing order is indeed 1,2,3,4,5,6Answer.
Transmission control unit for a 1990 Pontiac transport?
Check on the engine block or intake manifold of your motor. Most engines are cast with that information right on it.
there is a rev limit setting in the ecm so you dont over rev the motor
Grand - 1990 was released on: USA: 18 January 1990
The question you ask is too involved for a proper answer. You may want to go to a car parts store, and get a repair manual for your car. They cost about $16.00 Or, go to a Public Library.
