ill fitting NAPA drier.. ackits better?

-DeeT on Wed July 15, 2009 12:06 PM User is offlineView users profile

Year: 1993
Make: Honda
Model: Civic
Engine Size: 1.5L
Refrigerant Type: Freeze-12
Ambient Temp: 90
Pressure Low: vacuum
Pressure High: 100
Country of Origin: United States

As you can see from my gauge readings, the original problem I'm chasing is a restriction in the system. I currently suspect the expansion valve. Before I attack that, though, I have another concern: the drier I bought from NAPA doesn't (quite) fit, and I'm unsure whether the problem is their fault or whether I have one of those weird "in between model years" cars that doesn't quite use the same parts as other cars in the same model year. Before I purchase a new drier and proceed with the repair, I'd love to know what's going on.

The original drier (from when the car was new) and the new NAPA drier have the same overall size and shape and are both compatible with the mounting hardware. However, the NAPA drier has inlet and outlet holes which are so large that the o-rings that came with it are too small to effect any seal against the walls. Especially telling is that the protective rubber cap that came with the NAPA part cannot plug in to original drier!

I checked NAPA's online computer database and the drier they gave me is the correct NAPA part number. I'm slightly worried that if I purchase a drier from ackits.com, I might have the same problem, not because of the vendors, but because my car is an oddball.

Is there any way of verifying the inner diameter of the inlet and outlet of a drier before purchasing it? If so, I am happy to measure the original drier's bore size.

Thanks for your reply, but I might not have made myself clear. The outer mounting dimensions aren't what I'm concerned about. It is the inner diameter of the inlet and outlet holes. The NAPA part has inlet and outlet holes which measure 10.2 mm ID, which is so much larger than the o-rings that it makes a seal impossible. The original Honda part has a stairstep seat for the o-ring, with an entry diameter of 9.56 mm, shrinking to 8.45 mm at the bottom of the seat. Is there a way to confirm this measurement?

Not today as I'm out of stock. Should have some in next week.

I'll keep an eye on this thread. I'm not in a super hurry to finish the job and I definitely want to put good parts in there! When you get one in, if you could measure it, that would be fantastic.

Post back in a week to remind me.

Maybe better than posting back in a week: how about if I place an online order for the drier, the expansion valve, plus whatever else I can think of that I might need (feel free to suggest here!), and include a note with the order (does ackits.com have a facility for this?) reminding you that I'd like the drier ports measured. Will that work?

Thanks...

There is a text filed box for additional information.
