Heater core replacement


Inspect/Replace 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.
f74-01.gif 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.

My ford truck smells of antifreeze?


You have a bad heater hose and it's being pulled in the cab, if your ucky. Otherwise you will have to pull out the heater core and replace it. A new one runs about $75.00 and can be bought at any auto parts store if you wan to try this on your own post here and I will give you the proceedure.

Heater blowing cold air


Hi!
It appears we have an Air lock scenario and you will need to perform a system Bleed.
Park the vehicle on level ground, when cold remove coolant filler cap, start engine and leave to idle, turn heater on full and blower to max. When engine reaches operating temperature watch and listen near coolant filler, keep clear as gurgling and hopefully a boil over should occur. Top up with very warm coolant and wait as it may do it again.
Check for heat inside vehicle if warm replace coolant cap but keep an eye on temperature gauge as the ~Air lock may have moved on from heater matrix/core so proceedure needs to be carried out again from COLD.
If No change then look at thermostat but I'm sure your problem lies with the heater Matrix/Core!

Heater matrix leaking


You'll probably have to remove the old leaking heater core from under the dash.A chiltons or haynes shop manual would be very helpful in telling you the actual step by step proceedure for removing the old core and installing the new one.I've replaced several heater "cores' and it involves a good bit of body contortion to get you head under the dash to see what your dealing with,but I,m confident that you can get the job done.Don't skip any steps here cause that way leads to frustration.Be sure to have a small bucket or tuperware container handy to catch any excess antifreeze before it soaks you carpet.
