its leaking under the car around where the dash is
You will have only cold air coming thru your heater ducts if your core is defective.
Need to know what year and model the truck is. 1992 Chevy k2500
The Chilton manual at your local Lib. will have a diagram of the process. It's not an easy task- if you know what you're doing it may still take about five hours to do fully . SOrry.
I need to know how to place the two hoses from the heater core to engine it's two pip's coming from the engine upper and lower from the core right and left can you match these too for me please.
buy a Chilton manual and it will tell you most of what you need to know.
In my experience the heater core is by the passenger seat. There is a web site that may be able to help you out more. http://www.l81vetteregistry.com/tech/ Let me know if this helped you out.
You know the heater core is bad when your truck leaks antifreeze onto the floor of the passenger side.
If water is dripping out of the heater core it is about to go.
If you have not done this before, it is a very time consuming job. Replacing the heater core is not the problem. Getting to it is. Unless you are willing to start removing panels and know how to remove them without damaging the plastic panels and clips, I suggest you take it to a professional. It is just a matter of removing enough to actually get to the core. Once you get to the heater core, first drain the radiator enough to get the level below the heater hoses. Remove the heater hoses, and then remove and replace the core.
On the 1994 BMW 530i, the heater core is located under the dash in the engine compartment. You know the heater core is bad when it starts to leak.
What problem, what year, and what do you need to know?
