No Heat, blowing cold air

My heater will not blow any heat, just cold air. I let the car warm up and the 2 heater core hoses are both cold. All the other hoses are warm like they are supposed to be. Is the core clogged or is there something wrong with the thermostat housing maybe? It has a new thermostat but i figured at least the hose going to the heater core should be warm? Thanks

it sounds like you have a duff thermostat. take it out and place it in a cup of boiling water out of a kettle, it should open. if not theres ur fault.

it could also be a blockage somewhere between your engine and heater matrix. go to your local motor factors and buy some coolant system flush.

flush your coolant system.

Well i've already put 2 new thermostats in it in the last year. And i flushed it out a few days ago. Just wondering why the big hose coming from the thermostat housing is warm but the smaller one from the housing going to the core stays cold. i'm guessing the heater core is clogged up but i undid both hoses and tried to back flush the heater core but it wouldn't even let any water through.

Why not try removing the heater core itself to see if it's clogged? It's not exactly a fun procedure, but it's not too difficult, either.

Instead of removing the core, remove both the hoses from the engine block, and force water through the core to remove blockage. There's likely some rust built up in there.

Replacing the heater core would be the right way to fix it, but this might get you some heat to survive until you feel like replacing the heater core.

I tried flushing it again and was able to get the water to flow through it finally. How hard is it to replace a heater core on a focus? Do you have to remove the dash?

It's in the lower part of the center, so you'll have to remove everything in the center of the dash- radio, AC controls, etc. I'd guess that removing the console would be helpful, but maybe not needed. It will be some work, but it won't be horrible.

Have you checked our Complete How-To Archive? See my signature for a link. If there's not a thread on it, maybe you could take some pics and document your experience to help everyone else?

I looked- no instructions for heater core removal, sorry.

It is a drag doing heater cores. I've done 3 on different cars - never fun. On the flushing technique have you tried connecting your garden hose sealed to one of those Prestone flush kit hoses and just leave it on on the inlet side to see if anything breaks free? Also, what about compressed air ? Good luck!
