Dash bracket for heater core - 1997 Volkswagen Jetta

1. Disconnect the negative battery cable and drain the cooling system.
2. Remove the instrument panel and center console to access the heater core.
3. Disconnect the heater hoses from the core and remove the mounting bolts or screws that hold the core in place.
4. Carefully remove the old heater core and any remaining mounting brackets.
5. Install the new heater core and reattach the mounting brackets and hoses.
6. Refill the cooling system with the recommended coolant and water mixture.
7. Reinstall the instrument panel and center console, and reconnect the negative battery cable.

well if there is enough room to remove it then you don't need to pull the dash. there should be two small brackets or a big bracket holding it down after you remove the cover. and you also need to remove the hoses from the other side of the fire wall. once you think you got it all lose then pry easy on it to make sure nothing is stuck. itf it wont move I am guessing you missed a bracket or screws. if you have a small mirror use that and a flashlight to look above the heater core to see if you missed something. they do get stuck but not always.

Please don't forget to rate! Thanks!

Please rate and have a good day:)

You do not have to do anything with the air conditioning, its all inside car under right side of dash. 1. go under hood and unhook heater hoses and bracket( if equiped) from core tubes. 2. go under dash right side remove 13mm bolt far right under dash thats so you can pull dash out a little ways to get cover off heater where heater core is.3. 1/4 in. socket set and 1/4 in. socket take screws out holding cover on look close there is one hidden top far right can't remember how maney 5 or 6 i think, screws all out use a little finess and remove cover and there will be your heater core. Good luck.

NO, BUT THE COMPLETE HVAC MODULE NEEDS TO BE REMOVED. THIS IS BASICALLY THE LARGE BLACK AIR DISTRIBUTION BOX LOCATED UNDER THE RH SIDE OF DASH. THE RH BODY MOUNT BUSHINGS ARE ALSO GOING TO NEED REMOVAL & THE BODY SLIGHLTY RAISED TO GAIN ACCESS TO CORE UNDERHOOD.

You have to pull the dash and all the lower fascia, then remove the box that houses the Heater Core Take the clamps off the heater hoses from the engine compartment side of the firewall and disconnect the heater hoses. Disconnect the bracket that holds the heater core in place from the inside of the passenger compartment (if present.) Carefully remove the heater core and discard it. Install a new heater core reversing the above steps.

You have to remove the dash in layers. There's a whole bunch of screws to take out. The heater core is located in the middle of the dash near windshield when you get that far. There are a couple of brackets that hold the heater core in place, remove the heater hoses and pull out heater core. It's quite a long process so give yourself plenty of time.
