After getting the engine back together in the 97 2.2, the AC bracket will not line up with all the mounting holes in the block. One of them is about a 1/4 inch off.

Someone who I had hired and then fired to do an engine swap had brought an engine from a 93.

I am wondering if he got the wrong bracket.

Anyone know if the AC mount bracket for a 93 is different than the 97?

Otherwise, I must have put it together wrong with the alternator bracket. With the compressor installed the bolt on the tip ( right side) of the bracket doesn't line up and the compressor is out of alignment with the crank pulley

The bracket I am referring to is number 17 in the diagramPosted Image

i'd get one for the engine you need, they should be easy to find. i know i've got one somewhere lying around, others would too.

that being said - #17 doesn't affect aligment of the compressor to crank pulley does it - i think it's #16 that does that - so maybe it's #16 that you need? i've seen that #17 bracket look different between different engines.

can you mount the compressor without using that bottom #17 bracket? install the top two bolts into the compressor and top two holes in the #16 bracket ?

Well I installed that compressor with both brackets, but just the one bolt on the bracket 17 would not line up. Like I said, though, with it installed that way, it was out of alignment.

So what you say, makes sense, that the # 16 would be the culprit.

I wish there was a diagram that showed all the washers and any spacers. Maybe I just installed it wrong.

Can you see on yours washers or spacers that would affect the alignment of the other bracket?

Might try loosening 14mm fasteners on bracket half 16( i think all are the same length no spacers) and even the 4 hrizontal compresser bolts, allowing every thing to "knit together" before torquing to spec, and esp if 17 is just a tad off.

no spacers or washers on those bolts. at most just a washer under the bolt head, just typical stuff, nothing that affects alignment.

that said - i now recall that i almost never install both of those bottom bracket bolts. they're unnecessary and one is really difficult to get in, lined up, and tightened, so i just skip it. with 3 other bolts on a non-structural part like that it's way overkill to have all 4. alt gets 2 bolts and a/c gets 4? nah :clap:

i have always used the bracket that came with the car, not the engine. but i have only done a couple of swaps.
