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.

SOURCE: How do I cange the heater core in my 1995 Chevy

Start by removing the panel under the dash on the passenger side. You will need a regular phillips screwdriver and a snubby 2-3" phillips later. Also get a 1/4" socket set. First thing, go under the car and remove the heater hoses from the firewall and twist out the drain spiggot. Then go back inside the car. The heater core sits under the radio. Under the core is a tray used to catch the leaking antifreeze and drain it out the firewall. You need to remove this tray. It has 6-8 screws holding it. Once the screws are out it is tricky removing it with the center console in, but it can be done-twist and bend. Then remove the screws holding the core in place and pull out the heater core. One note on the replacement-got mine from Oreilly's for $20-the two lines coming out of the heater core swivel to line up with the holes through the firewall. If you don't swivel them it will never seem to fit. Then reverse the above order, fill up the fluid, bleed the air off and away you go. Took me about 3 hours total in a parking lot. Ruined a shirt, but got it done. You will also cuss being upside down under the dash. It's a small place for a 240 lb. guy :) This was for a 1993 Beretta. Expect some bloody knuckles and a few mental breakdowns.

Good luck, and rated the help!!!
REMOVAL & INSTALLATION CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

For heater core removal on these vehicles, please refer to the procedure for vehicles with A/C.
1994-96 VEHICLES
See Figures 1, 2 and 3

  1. Properly disable the SIR system, as outlined earlier in this section.
  2. Disconnect the negative battery cable.

SOURCE: How to replace a heater core in a 1994 chevy 1500

As with all vehicles it seems the first part that they build around is the heater core. It is under the dash above the floor housed in a black plastic sealed box. Sealed with goop. Locate that box and start removing everything around it that is peventing taking the cover off. Of course disconnect the heater hoses under the hood a thefirewall.

Warning it is never as easy as it sounds.

SOURCE: how do i change a heater core on a 1995 chevy

Changing the heater core is a simple process. Getting to the core to actually change it can be daunting if you have never changed one before on a corsica. All cars are different in that you have to remove enough dash parts to actually allow you to get to the core and they are all different. This is why labor charges are so high for changing a $50 part.I have never changed one on a Corsica myself. If you do this yourself, take digital photos as your go along so you will be able to put everything back in the correct order. I know this is not really the answer you want, but you are probably not going to get detailed instructions on how to do it, other than just remove enough parts to get to the heater core. Go slow and figure out how the parts come off and what parts to remove. Not an easy repair even if you have done it before. Good luck.

Will heater core on 1995 lumina and 1994 lumina interchange


The easiest way to see if a part will cross to other vehicles is to use an online parts store. Napaonline.com, autozone.com, oreilly's.com, etc. look up the part for the 95 and then check to see if the same part is used for a 94.

You have a coolant leak, either in the heater core, or from the heater hose that feeds heated coolant to the core.

Need to replace heater core on 1997 Chevy Lumina


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.

Where does the hater hose hook to the back of the motor when changing the hose because of a leaking or weak connection to the heater core


If you have a 3.1L the heater pipe connection on the intake is a quick disconnect made of pot metal and they crack at the fitting. The other line is tin and connects close to the same place.
