    It is most likely under the dash. Most heater cores are found there and you will know when you look under the dash to find hoses coming in through the firewall. Hopefully it is fairly accessible.

Inside on the passenger side under the dash you will find a large black box. It has several screws holding the cover on. You remove the core from there. It helps to take the jockey box out first. But, the hoses to the core are outside under the hood on the passenger side. These usually have C-hook clamps on them. That means you need a special tool to get the clamps off, then the hoses slide off the rubber gromet on the core from the outside, by simply pulling on them. You can find the two hoses on the far left when you are outside on the front of the vehicle. They project from a small are on the side of the heater fan housing. Remember to save the clamps, most new cores do not come with.

Need to know where my Heater Core hoses hook up to on the engine? I see the Hoses but is there a seperate part that the hose connects to?


The best way to locate a heater core hose is to determine where the heater core is located. Many vehicles have the heater core inside the dash. Other vehicles, usually larger vans and trucks, will have a heater core box inside the engine compartment. Once you have determined where the heater core is located in your vehicle, that will allow you to easily locate a heater core hose. If the heater core is inside the dash, you'll need to examine the firewall for the hoses. If it is in a heater box, you'll need to look around the engine compartment for the box.




Heater cores located inside dashes can be very difficult and time consuming to replace. Depending on the layout of your engine compartment, it can also be difficult to locate a heater core hose. If there is very little clearance between the engine and the firewall, you may have difficulty finding the hoses. You might need to use a flashlight to look from the underside in some cases. You will typically be able to identify the heater hoses where they enter the firewall by looking for two two small diameter hoses that protrude into the engine compartment. You can then trace those hoses to their other ends, where they will typically connect to a thermostat housing, the radiator, or a t-connector.


Hope this helps.
