Hello I have a 1993 for f-250 7.3 nonturbo and I am trying to locate the AC evaparator hose drain so I can clean it and I can not find it anywhere can someone please tell where it is. Thanks

 

There is no hose drain off the bottom of the evaporator on these trucks. It drains into the fender, from out of the bottom of the heater box

 

How do I check to make sure it's clean

 

Depends on what it's doing.
I imagine there are leaves in it, causing it to back up, and come in the cab on the floor

Here is a eveporator being removed from that vintage truck

Once removed, here is the leaves on the bottom I mentioned

Unless you are removing the evaporator, you really won't get to these

There is a solution to your problem though. I need to move this over to the articles section
Pretty easy to do.

That should work. especially if you do it with this

If the problem persists, let me know, we will try a "more drastic" solution

 

I have already cleaned both cowl drains out and cut the old sealer out and put new silicone in I think these reasons were why the water was coming in the cab won't know until it rains really hard I just wanted to check to make sure the ac drain was clear as well

 

Instead of taking a whole bunch of things apart is there anywhere I could drill a couple small holes and let it drain through that so that when they plug up I could use air to clean them out if I can where should I drill

 

I don't recommend that. You will be pulling exhaust into the cabin
If that is what you decide to do, study the picture of the open box with the evaporator missing, and drill away.
DON'T hit the evaporator.

Clean out the sides. there is where your water is coming from

 

Can I unbolt the case around the Evaparator under the hood and clean it out that way

 

only 1 side comes off, and sadly, the leaves come in from the other side.
Where the evaporator drains, there usually isn't any leaves.
I guess you could pull the fan motor out, and clean it out from there.
would be a real PIA on a diesel truck.

 

T

there might not be any leaves I just was going to clean it out while I was cleaning the cowl drains out can I take the one side off and be able to see if theirs any leaves or can you not even see the other side

 

Sometimes, if there isn't a problem, it's best not to fool around and make one.
I would probably do like my dad used to tell me, and just "let it develop " before fixing it, if it isn't a problem yet
