My GF is traveling for a week, and is leaving me her car. So its time for a fixing spree on the 99 XJ! :explosion
I have a few questions about the different fixes I have planned, as well as looking for general advice. This is a placeholder and I will update over the next few days as I continue to read up.
The things I need to do:
Fan Clutch:
Seems pretty straightforward. I ordered the Hayden 2625 clutch (this is my DD and don't want a loud ass fan).
Harmonic Balancer:
Sounds like a pain the ass. I'm gonna order a Mopar one tomorrow from the dealer, it sounds like this is one of the things you don't want to go aftermarket with. Also, getting the puller/installer from AutoZone or wherever.
While I'm at it - I understand I should replace the timing chain cover gasket. Just order a fel-pro one from Rockauto? Do I still need the black RTV gasket sealant?
Any point in doing rear main seal while I'm down there? Should I replace chain and sprockets too?
Replace cracked exhaust manifold:
Going with the APN Header. Will post more questions as I research this one.
Replace oil filter adapter seal:
Should I do the straight-out mod, or keep it at 90deg? Does the straight out mod require any major modifications?
I hear this is one of the worst XJ fixes. any tips?
Replace battery cables (big 3 upgrade):
I am still running the stock alternator (113A?). I bought 4 AWG welding cable, and tin-plated copper terminals. I plan to do this all myself using the crimp and solder tools at my work.
I was thinking I may as well upgrade the alternator and do the 136A upgrade. Is this stupid? I have 188k miles, and stock alternator. I've replaced almost everything else electrical - why not replace the alternator while I'm working in there? I plan to put in a nice stereo/sub setup and possibly upgraded headlights at some point. Never a winch or anything like that. Is this a good/bad idea?
Replace Temperature sensor/sending unit:
Recently, my temperature sensor stopped updating, and is always sitting just over 100. I assume(hope) it is the front sensor - but I haven't read up much on this yet. MY understanding is my 99 only has the t-stat housing on the front which is hte sensor and sending unit. I should start with jsut replacing sensor and not mess with housing/sender unless I know it is broken.
Thanks for everyone's help with the million questions.
