SOURCE: 1995 corvette heater core replacement cost estimate

225.00 bucks including parts labor, you might find a local mechanic will do it for 100.00 buck for labor and you buy the part 49.00 buck. lots of GM mechanic are laid off and economy is slow and you might want to advertise on craig list needing GM mechanic. my best secrets is drive back to the GM garage and ask any mechanic who does the side work and you will be surprise. keep in mind dont ask the shop manager, believed me every dealership has one or more does a side job and good price, no shop rate. hope that help some good luck.

Dash needs to come out, or at least pulled back enough to gain acess to the blower box. It sounds like a impossible task but not really too bad. Lots of screws and wires. If you have no knowage of working on cars it may be best to have someone do it.

Here's a link to replacing your heater core,it's a job,be sure to replace your seals that the boxes connect to each other or air will go thru,your's is probably dry rotted.Also make sure your outlets are pointing in the same direction on both heater cores,if they are different,then your heater hoses going to them will be too short,happen to me.

Heater core is leaking in a 1981 corvette, has a R-12 a/c system where can I get this part and at which auto shop can fix it?


You can order the heater core at any Auto Supplier
that specializes in A/C, heater,radiator,etc parts,also
maybe an auto parts store

I will be sarcastic here. Anyone owning a corvette, should
be doing their own work

If I could buy a stingray brand new, at age 19 & do a frame up
restoration,bore the old 327 & sleeve it at 22, & rebuilt the trans,
without any help or knowledge,you should be able to install
a heater core.

I have a 1990 corvette convertible with a leaking heater core. How do I remove the heater core? From the engine compartment or by removing the dash?


you have to remove the dash and in most cases the seats are even removed to help with the extra room. One corvette forum that i really love is www.smokinvette.com . Lots of useful info there.

Good luck

How to remove heater core in 1991 lincoln


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.

Water on floor board on passenger side of 1991 Buick Century


Engine coolant will feel oily and the windshield will fog up and the car will stink. If it is just water it could be coming from the passenger door weatherstrip at top. The ac drain tube , if stopped up will also leak water in the floorboard.

Where do i locate the heater core in a 1991 pontiac 6000le


The heater core is inside the heater case. It is the same plastic case that houses the blower motor. Usually they are replaced under the hood near the firewall or under the dash. I would look at the free online repair manuals provided by parts stores such as autozone.com . They should have the info you need for your particular model.
