TJ or WJ 4.0l in XJ from previous owner

so realized i have a TJ or WJ 4liter in my XJ.

I have searched all over and cant seem to figure out how i need to deal with my water pump issue. Stock XJ water pump is only held in by 3 bolts. I have re sealed it again and rock it for 8-10k then re seal again lol.

I have been freshening this bad boy up and finally want to address this once and for all...

What options do i have for this since the WJ and TJ water pumps have 5 bolts 3 sharing the same mounting as a XJ.

Also wondering if anyone has made motor mount brackets for this swap. im running some thick steel spacers right now for the mount bolts.

You can drill and tap the other bolt holes or have you tried using Permatex Right stuff it's a tough sealant and should not leak . when it dries it will be like rubber not like silicone .

Iron man 4x4 makes mounts for the swap. You also might talk to them about the water pump issue

Maybe I'm missing something, but can't you just custom route coolant lines where you need?
And get a wj pump?

Brown Dog will sell you mounts for the swap as well. Get the proper water pump for the motor. I just walked out and looked at the 04 WJ motor in my 88 and with the 5 bolts securing it to the block, there should be no issue getting it to seal. Does it have the 99+ intake on it? Where's the alternator located?
