fixed my heat problem

so i was having problems with my heat for awhile now, but in the last 3 days it had gotten worse to that there was no heat at all,
so i took it in to chrysler and they tested the system and said it needed a thermostat and they wanted $211 plus taxes to do it,
I said no way and bought the new thermostat and put it in myself and got the car upto operating temp and it still had no heat, so i took the car to another garage and explained what was happening and the mechanic said right away that the heater core was plugged and the only was to fix it was replace it which seems like alot of work when i looked in the haynes manual,
I was able to unhook both hoses at the heater core and then i stuck a garden hose in the heater core and turned the water on and reversed flushed it but i switched back and forth between in and out on the heater core to loosen it up and i got quite abit of rust chips out of it and now my heat is working great.
btw the rest of the system had new antifreeze put in about 2 months ago


just thought i would share this with everyone.

My dad took their '91 Spirit(3.0) into a local shop to have the coolant system flushed and they had to use hydrochloric acid to get the heater core completely flushed out.

Periodic maintenance would prevent build up.

i have only had the car for since last feb. and the heat was working enough then and the whole system was drained in the summer when i had the rad out and so i thought that it would be ok this year but i guess i was wrong.

it's not to hard at all to do
there isn't to much room but right behind the engine at the top is 2 heater hoses going into the firewall what i did was unhook both hoses right at the firewall and with a garden hose with one end cut off it fit perfectly into the heater core and so i stuck the hose in one side first turned the water on for a minute then shut it off and moved it to the other side and i did that about 6 times and you could see rusty water and chips of rust coming out.
and then i just hooked the hoses back up and it worked.

Kyle, I love the colour of your car.

Seriously, think about tinting your windows on your car. It has a VERY DRASTIC change in the paint and the overall look of the car. Makes it look very mean.

That sounds like a good idea with the garden hose, maybe I'll give it a try.

I just spend $55.00 for changing a thermostat. But it does not help the inside temperature going up.
I prepare to flush the heater core.

I checked the hosts on the fairwall. The left hose is hot and the right one is warm with my face facing the car. Does that mean the heater core is plugged?

Do I need take out the air in the heater after flushing before I hook the hoses from the engine to the heater?

sounds like the heater core is being plugged by something and no you don't have to get rid of the air in the heater as it will be full of water if you use a garden hose then it will mix in with the rest but you may have some air to get rid of after you hook everything back up and have it warm up then open the bleeder screw on the thermostat housing that is what i did anyways

Question I am not sure which one is the bleeder?

Thank you kyle712.
I'm a newbier.

Is that bleeder like a "nipple" ? Any picture?

Should I hook anything in another hose of the heater when I put garden hose in one hose of the heater?

I changed my coolant Oct, 2002. Should I change it and flush the whole system?

Could I just switch the hose going in the heater to the hose going out the heater? Is this call" backflushing"?


Sorry about these stupid questions.

no you shouldn't have to change the coolant afterwards i didn't and just unhook both hoses at the heater core and just hook a garden hose up to one side and turn it on then switch to the other side do that a few times and that should work for you you don't have to hook any other hoses up or anything and yes the bleeder screw is sorta like a nipple right at the front and top of the engine just open it up until no air comes out then close it
