Water Leak

When you say "The A/C was completely replaced" do you mean ALL components, both in and outside the firewall?

If the mechanic didn't replace your evaporator coil inside, it's time to open up the checkbook and examine the condition of the evaporator coil and the heater coil. In the heater coil, the engine coolant runs through this miniature radiator to heat the cabin. That is what is probably leaking. If he didn't replace the evaporator, do it now while the interior is opened up.

OTOH, if he DID replace it, he may have erred by not exam> I have a 1992 2 door Ford Explorer.

components, both in and outside the firewall?

Here is a list of replaced parts.

Mike,

It's a typical mistake according to my favorite wrench turner. It looks like you missed the evaporator when you replaced "everything". The evaporator shares space with the heater coil. You're going to have to open up the dash behind the glove box anyway to replace the leaking heater coil. Opening the air box for the heat and A/C means a lot of work upside down and cursing. That's why it's typically not done. Take some good advice from someone who went through A/C conversion hell on his 1992 Explorer. I started out with the same conversion that you did, but I had to add a evaporator and a compressor manifold. But I now have a truck that keeps me cool in Florida weather.

Have your A/C shop recover the R-134 and replace the original evaporator coil when you replace your heater coil. At this point, these are the most inaccessible parts of your A/C and heater system that are now original to your Explorer. Replace the evaporator and heater coil while you can get to both, and save some on the labor charges. Then the only point of failure you would have left would be the A/C manifold (i.e. the hoses, easily accessible in the engine compartment) And make sure the receiver/dryer (the silver can with the two refrigerant lines connected to it) is replaced. This has to be done any time the system is open to the atmosphere, to keep moisture out.

Good luck.

Regards,

Richard

take it back, they didnt check for leaks

Hi! I just had the same problem this morning... I wake up, start up my 91 Explorer to warm it up and I notice that antifreeze smell...I now have a decent antifreeze/water leak that I cannot tell where its coming from (but its near the dash, but not leaking inside the car). I have plenty of warm moist fumes coming from all vents including my defrost....but my heat and a/c are fine. Ive had the radiator and water pump replaced, plus the fan clutch. Do I have the same problem?? I remember my mechanic said he "blew out" the heater coil but did not replace. Can you please help me? Ive had this truck in and out of the shop all summer long....with the same mechanic fixing it. He also replaced the head gaskets. Please help!

I would think your mechanic blew a little too hard on the heater coil maybe swallowing some antifreeze in the process. You need to find another mechanic. If this guy is trying to locate the problem by just replacing everything he can think of, HE NEEDS TO BE REPLACED!
