Heater core leaking


Must replace the heater core. Its usually a very hard job that requires disassembly of the dash. If you insist on doing the job yourself, I suggest getting a repair manual from your local auto parts store so you can use it as a reference as you work. Here is a link to a video on a 98, yours will be very similar: http://www.youtube.com/results?search_query=1991+Pontiac+Bonneville+heater+core+replacement&sm=12

Do I have to drob the steering colum in my 1991 licoln TC in order to replace the heater core?


No you do not have to drop the steering column to change the heater core. It should be located under the passenger side of the dashboard. The easiest way to find where it is located would be to look under the hood for two hoses that go from the front of the engine through the firewall and that will tell you exactly where it is located. To replace the heater core you will have to disconnect the two hoses under the hood from the heater core then remove the heater box from underneath the dashboard.

19991 civic hatchback. Getting hot air but no


There is a blower motor under the dash, behind glovebox. Loosen 3 retaining screws holding motor housing, drop motor housing and blower motor unit. Replace blower unit. The problem involves the blower resistor. This piece must be replaced but might be easier to replace the entire blower motor unit.

What do i have to remove to replace the heater core in my 1991 chevy s10 with a 2.8 v6


Draining the Cooling System
  • Park the vehicle on a level surface. If the engine has been running allow it to cool completely.
  • Drain the cooling system. Remove the radiator cap from the radiator. Locate the petcock valve on the lower corner of the radiator. Place a waste oil collection pan underneath the petcock valve and turn it counterclockwise to open. Allow the cooling system to drain completely.
  • Label and remove the heater hoses from the heater core. The heater hoses will connect to the heater core in the engine bay, on the firewall, on the passenger side of the vehicle. Use either the Phillips or the flat-blade screwdriver to loosen the hose clamps that secure the hoses to the heater core. Then pull the hoses off the heater core.
Removing the Heater Core
  • Remove the heater core cover. Move to inside the passenger compartment. Locate the heater case. It will be bolted to the firewall, below the dash on the passenger side of the vehicle. Use an appropriate sized socket or wrench to remove the five screws that connect the heater core cover to the heater case, and remove the cover.
  • Remove the steel straps that secure the heater core to the heater case. Unscrew the four screws that connect the steel straps to the heater case using a socket or wrench and remove the straps.
  • Remove the heater core by pulling it out of the heater case.
Installing the Heater Core
  • Place the new heater core into position inside the heater case. Be sure to carefully guide the inlet and outlet tubes through the holes in the firewall.
  • Reinstall the heater core retaining straps, by reinstalling the four screws that secure them.
  • Place the heater core cover into position over the heater case and reinstall the five screws that secure it.

Refilling the Cooling System
  • Reconnect the heater hoses to the heater core. Slide the hoses onto the inlet and outlet fittings that extend through the firewall, and tighten the hose clamps.
  • Close the petcock valve on the lower corner of the radiator by turning it clockwise.
  • Refill the radiator with a 50/50 mix of antifreeze and water.
  • Reinstall the radiator cap onto the radiator.
  • Run the engine and visually inspect for leaks.
Good luck and take your time.

Where is the cooling fan relay on my 1991 pontiac 6000le 3.1L?


I believe the cooling fan relay is located on a metal relay center bracket on or near the firewall. It should be a relay that is oval shaped, with 5 pins. I hope that helps.

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.

Cant find heater core hose


The heater core hoses go into the firewall area on the passenger side of the engine compartment,But I think you should look for the leak by adding water and with the engine running,watch to see if you can locate the leak,the location you are describing sounds more like a freeze plug or even the head gasket,But look and see first.

Timing a pontiac 6000le 2.5 engine


first check to be sure the vavuum lines at the throttle body are in there correct places.
on the main pulley of your engine, the one on the crank shaft there will be a little notch on it. mark the notch with some chalk or a dab of white paint. then loosen the bolt that holds down the distributor until you can turn the distributor. turn the distributor a little bit, snug the bolt up and try it. once you have the car running you will need a timing lite to set the timing to the correct timing mark. which should be 8 degrees before top dead center for you car.
