Ok.

Needed to know what size wrenches to use on the Evaporator.. since they are bigger than 7/8". If anyone knows.. please please post.

Another Question. My car is a 93 Base model. So i've been reading that there are 2 different evaporators out there.. the Nippondenso and the MANA. So now i'm sure i have a MANA evaporator waiting to go into the car, but not sure what i will be taking OUT of the car. So if they are interchangeable.. which i hope.. but doubt. Please let me know. Thanks in advance.

From Ray at Malloy Mazda:
Only Tourings have Japanese air (Denso-Nippon)

All base models and R1's and R2's have Mana system.

k great. now i just need to know the sizes of those nuts that hold the evap in on the firewall so i can go purchase the correct wrenches.

that's not true. I have a 94 touring and have Mana stuff.

Typically I just need my big wrench set - 21mm, 23mm, and 26mm - that will do all AC lines no sweat. Some of the smaller ones might be 17mm or 19mm, but you should have that in your toolbox .

That is the general rule - Tourings have Nippondenso, R packages and bases have MANA. MANA is cheaper and easier to get parts for.

A good crecsent wrench is what I use on all the large a/c lines. The fittings are not super tight since they have o-ring seals. Always use a wrench on both sides of the fitting to keep from twisting them.

well only problem is that i have like... ZERO room to move the wrenches around because of the ABS unit...

Agreed. According to the Service Highlights manual, Nippondenso was the standard, but MANA was optionally available to U.S. and canadian models. I assume the Touring was the standard and R/Base models were the option


parts are not interchangeable between the two systems, with the exception of the A/C condensor (this is an assumption). The mounts should be the only difference on the two condensors.

well i figured a way around the damn thing by going at it from the side.

the nut sizes are..

TOP: 19mm, 28mm.. not sure on the 28.. but it was bigger than 1 1/8"
Bottom: 17mm and 19mm

got them loose.. now just gotta pull it from under the glovebox.

Bologna. I've done it The most I would have done is loosen the ABS mounting bracket so I could move it slightly. I replaced every o-ring in my a/c system when I converted to 134a.

most 93 will be nippon denso.

it was a MANA.. and i was able to remove it. Now i just need to figure out why i'm building too much pressure in my system.

mad_7tist

what are your gague readings? how much freon and oil did you put in the system? you went from r12 to 134? or was it previously converted?

it was previously converted to R134a. I'm almost certain that there is too much freon in the system. The previous mechanic had written down 18oz. for the system.. and I think the tech that put the freon in this time put more like 24oz. So i'm sure thats the problem.
