VW Heater Core Replacement - 1993-1998 VW Jetta and Golf - YouTube

The heater core is located in the heater box, under the passenger side of the dash. Most FORD heater boxes are snap-clipped together, and if you remove the rear panel from the heater box, you will see the heater core...it looks like a smaller radiator...twist the heater hose off of the heater core (x2) from the engine side and gently remove the heater core from under the dash. When replacing the new heater core, be very careful re-installing new hoses to the core...it is a fragile thin metal that can leak almost instantly if tweaked too roughly...replace all parts in reverse order of removal.

Remove the dash, remove all fasteners and seperate the heater core housing, remove the core. Install in reverse order. Its a tough job for a novice, i suggest let a shop do it.

In order to replace the heater core the entire dash will need to be removed from the vehicle. The heater core access door can then be removed and the heater core replaced. This is a huge job!

Ouch. In order to replace the heater core in a Grand Prix, you have to remove the entire center counsel and in many years the entire dash assembly. The heater core itself is located in a black plastic box, in the center of the vehicle under the dash. Its not an easy task to complete, however at least it is somewhat easy access to disconnect the lines coming through the firewall in the engine compartment(hint). Good luck and I hope this helps.

If it is necessary to remove the heater assembly, the cooling system must be drained before removing the heater core.
When a heater core leaks, a new heater core is installed or the old one repaired.
Heater Housing

• The heater housing is usually under the dash and must be removed to gain access to the heater core.
• Procedures for replacing the heater core vary with the year, make, and model of car. It threfore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.

The heater housing is disassembled to get to the heater core. Heater Core

• Remove the access panels(s) or the split heater/air conditioning case to gain acess to the heater core.
• Remove the heater coolant hoses.
• Remove the cable and/or vacuum control lines (if equipped).
• Remove the heater core securing brackets and/or clamps.
• Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing.
• To reinstall the heater core, reverse the removal steps.

When the heater core leaks and must be repaired or replaced, it is a very difficult and time-consuming job primarily because of the core's location deep within the firewall of the car. For this reason always leak test a replacement heater core before installation.

The heater core is located behind the dashboard. The entire dashboard has to be completely removed in order to replace the heater core. The time it takes to remove and replace this dash is usually about a few hours, thus the high $500-$600 pricetag, which I believe is decent.

No you do not, I think you mean the heater core, because its leaking, first unhook heaters hoses under hood (there may be a clamp on the core tubes that has to come off), next go under dash on passengers side, take the one bolt to the far right under dash by the dome light, thats so you can pull the dash out just enought to get the cover off the front of the heater box, behind that cover is the heater core, now that cover is held on with about 6 1/4 inch screws give or take 1 or 2 when you get the cover off you will see 2 straps, one on each end that hold the core in place, there are 2 1/4 screws in each one, remove them and core will come out. Put back together in reverse order.

The front heater core in your truck is inside the environmental station, which is inside the dash, the entire dash will have to be removed in order to access it, in order to access the heater core itself you will have to remove the environmental station, requiring the draining of the engine coolant and the a/c system. Your best bet is to buy a Haynes or Chiltons manual and follow the steps to perform this repair, or take it to your favorite repair shop. The core itself should cost about 60 dollars. I did my own and it took a good 5 hours to remove and replace everything. I hope this helps, let me know.

Your heater core needs to be replaced. The heater core is like a mini radiator, providing heat for the interior by coolant circulating from the engine, into the heater core, and back to the engine again. Like a radiator, a heater core can spring a leak, especially w/ age as a factor. This results in the leak inside the car, which also causes the 'smoke' you see, which is actually vapor form of coolant.
