SOURCE: how to remove heater core

You start by draining off some of the coolant. Open the radiator drain petcock on the drivers side of the radiator. You only need to drain off a half gallon or a little less. Loosen the two hose clamps leading to the heater core. You may have to twist the hoses slightly to brake them free. Now the fun starts. Remove the glove compartment by removing the eight screws at the bottom. With that out of the way you should be able to see the hearer control box. On top of this box is two cables. Remove them by gently prying off the slip clamps with a screw driver. there is also a holding clamp on both of the cables simply remove the screw on both clamps and the cables will come free. Now you remove the three bolts holding the box to the firewall. The ducts attach to the box in different ways depending on what model of suburban you have. Some snap together but most will have screws. Look closely before forcing the ducts apart! Almost done. there are three bolts under the hood on the passenger side. One is on the top of the a/c box two are below it. Only one is difficult to get to. It is located right below the blower motor housing. The easiest thing to do is to use a long extension and a universal joint with a deep socket. Some people take the inner fender off but I don’t recommend it as 16 bolts hold it in place. With all that done the box should be pulled strait out, just before it hit’s the dash, drop it down and out.

Heater Core - REMOVAL & INSTALLATION
CAUTION Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

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.

  • 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).

How do i install a block heater into a 2000 Celica GTS? Can you provide any pictures and/or useful links?


The heater core and evaporator are in a box together underneath the center of the dashboard against the firewall. My service manual seems to indicate that they both must come out at the same time to access either. Presuming this is correct, here we go.
Disconnect battery and wait half hour to disable SRS
Evacuate AC
Drain coolant. (It is not necessary to drain it completely.)
Disconnect AC liquid tube and suction hose. (Engine compartment firewall.)
Remove instrument panel and reinforcement.
Dicsonnect heater hoses. (Engine compartment firewall.)
q=tbn:hFn1BMnyjvA3XM::http://www.autopartswarehouse.com/images/product_images/thumbs_100/spectra/spi94655.jpg Remove heater core and evaporator from box.
Assembly is the reverse. Fill heater core and hoses with coolant to eliminate as much air as possible before installation.

I have a 1987 toyota celica gt and the heater won't come on, the blower works but no heat, fuses are good but no heat


This problem is specific to the Gen4 Celica (86-89). Intermittent or no heat heat is caused by cracked solder joints in the Heater Control Panel. You need to remove the panel and re-solder the solder joints. When electrical continuity is broken, the panel defaults to the cold setting. If you go over a bump and it touches again, you may get hot. Hence, intermittent or no heat. We have the complete DIY fix posted at www.st162.net and it's free. Pic below shows the heater control points to re-solder.
