The heater is blowing out cold air.


First, check if coolant is low, as that is often the cause of loss of heat.
Check if the heater core is leaking-if floor on passenger side is damp, it may be leaking. Changing out a heater core can be very easy or very difficult, depending on the design. On some more difficult ones, the entire dash has to be removed. I hope not in your case.
When coolant is full and engine warmed up, feel both heater hoses. Both should be hot, indicating the core is circulating coolant.
Keep looking for a leak, if you keep smelling coolant or have to keep adding.

2009 Jeep Wrangler Unlimited heater core replaced 3 times


if they have replaced it 3 times and still can't get the leak stopped
A. It not the heater core something else is leaking

B. there using a used heater core (which is my opinion is plain . . stupid)
C. the mechanic has no idea what he doing
First thing they should have done when car was brought in the 1st time was check for other leaks if it is the heater core still leaking the mechanic is installing it wrong or not geting hoses tight. the actual changing of the heater core takes only about 10 minutes and actually a easy process that anyone could do. What takes the most time is getting to the heater core because the majorly of the time the whole dash has to come out which takes hours

I would take your car somewhere else and have it fixed right and have them bill the dealership for the repairs

How to remove and replace heater core on a 2000 mercury marquis


the dashboard will have to be removed along with other components that are blocking you from accessing the heater core once you get to the heater core its a easy replace. if it is leaking in your car you can bypass the core until you can get it fixed by removing the two hoses going into the heater core and connecting them together with any piece of hard tube that can withstand the temperature of the coolant

88 bronco II, heater hose going to water is cold, and my heater blows cold air, is my water pump going bad? the return heater hose is warm, it was heating once in awhile now it don't heat at all just cold...


I would try flushing heater core to see if it's plugged. I don't think it's waterpump, your rig would be overheating if it was. Leaking is most common waterpump failure.

How to change heater core in a 2000 Chevrolet Silverado Heater core is leaking inside the truck


I believe on this model 1500/2500 gas w/ac that you have to first evacuate the a/c system and then remove the HVAC module [fancy wording for the entire heater box assembly] then remove the core from it once you have the assembly out of the cab. I also believe its about a 6 - 7 hour job and not one you'd want to try on your own unless you have quite a bit of mechanical experience behind you as it's not an easy one to do. It's also very easy to damage the new core when reinstalling the assembly back in the cab which will truly wreck your day if that happens!

I have a heater core leak on my 2000 chevy silverado V6, is there an easy fix?


You can bypass the heater core, you just wont have heat anymore. On the firewall of the truck, behind the engine, you will see 2 rubber heater hoses that go into the firewall. They attach to the heater core. Disconnect them and get a plastic connector, and connect the 2 hoses together with clamps to hold them down. This will stop coolant from going into the heater core, and no more leak.

Antifreeze leaking on firewall out of rubber elbow?


I had the same problem and it is the heater core. Hope the info below helps.

The heater core is inside the firewall under the center of the dash. It requires removing the center console to reach the plenum cover.

Drain the coolant. Be Prepared for a few skinned nuckels. First dissconnect your battery You will be working around wiring harness' so just tobe on the safe side I would disconnect the battery.The easy part is removing both glove boxes, remove the console remove the covers under the steering wheel remove the cover surrounding the the radio and heater controls, now remove the first plastic cover it will have two ports going into the center console, you might have pull back the carpet on both sides to get it out. After you remove that cover you have to remove the next cover that hides the heater core. When that is removed you should see the heater core there are four bolts two top two bottom holding silver bands remove these and the heater core will be loose. When removing everything make sure you get all the screws I missed two hidden screws and broke the cover. Some are torx some are nut heads.Now that is the easy part the hard part is removing the heater hoses from the back fo the engine. If the You are sure the heater core is shot usually coolant on the carpet is a good indicator just snap the two plastic pipes going to the heater core. This will make it easier to access the hoses. There is no easy way to remove these is is a matter of determination and patience. I would never change a heater core without changing the hosesyou will see that it will be worth new hoses because you will not want to repeat this procedure again.
