The downside is of course, no heat, or warm air to defrost/defog windshield. Changing a heater core is generally a labor intensive job. If you decide to do it yourself, invest in a good manual, or online source so you know how to get it out in step by step process. I would suggest checking alldata diy site, which cost is in the upper $20 range for 1 yr access to your vehicles repair info. You can print up any sections you want to bring outside to work on the vehicle. Good luck.

No heat and both the radiator and thermostat are new.

There are a couple of possibilities....

1. The heater core has been bypassed. If the core was leaking someone may have looped the heater hose back on itself. Check to ensure that the supply and return heater hoses are in place and properly routed to the firewall.

2. The heater core may be clogged. Age does a lot as does old coolant to clog up a heater core. To check the core disconnect the heater hoses at the block. Blow through one hose and see if you can get coolant/air to pass through the core. You can raise one hose higher than the other and pour water through or use low-pressure air as well. If the core is clogged, it may be possible to unclog it using a diluted drain cleaner. Pour the diluted cleaner into both hoses and let sit for a time, then flush with clear water. This may take several attempts. If it works it will save much time and expense. The unfortunate downside is that there is also the possibility of generating a core leak this way. But considering that if you hadn't tried you would have to replace the core anyway, you have nothing really to lose.

3. The blend door in the heater control box may be stuck and not letting air pass thru the core to heat the cabin. This one is hardder to verify.

If you are getting coolant inside the cabin the common cause is a leaking heater core.

You need to have a pressure chek done on the engine cooling system. this will tell you if you have any leaks. some that you can't see. this is the main reason for loosing heat constantly.

mcdevito75 here, Sounds like you have 2 problems First the water on the passeger side, it:"s most like luy a clogged drain for the A/C evaporator under the dash board, Check the drain hose on the firewal, just opposite the glove box, also if you can look under the dash on the pass. side and check the drain hose on the evaporatror. 2nd problem sounds like a bad heater core.

My heater not working, i replaced thermostat and radiator hoses, had radiator flushed and rodded, and still no heat. What is wrong?

Too much blockage in heater hoses or heater core.
Bypass valve may be stuck on "bypass" .

1. Remove bypass "Tees", but don't discard.
Replace with straight-through hose fittings.
The core may start leaking under the water pressure since there is no bypass hose.

Once the heater starts working, put Tees back in place. You need bypass protection or the engine will overheat.

Leaking heater core in a 2001 ford escort

take the 2 heater hoses at the firewall and connect them together. you just need to make a LOOP that will leave the heater "out of the loop" either buy a length of heater hose or get a "splice connector' so you can connect them together.

the heater bypass is quite simple, if you look at the firewall you will see two medium sized coolant lines, remove them from the firewall and link them together using a proper sized tube, you can purchase a kit at a parts store quite cheaply
