Advice on Refreshing a Gen 2.5

So I've been buying parts to refresh the engine and cooling system on a new-to-me 1998 Montero. The list below reflects what I've purchased (from about five different online stores). Note that I have bought OEM parts where possible. I will also be replacing all fluids (diffs, tranny, radiator, etc) and have the stock radiator re-cored. I know some of the folks in here have extensive experience bringing these old trucks back up to par.

Please let me know if you think I've missed anything. Many thanks.

Great looking Monty. I didn't see fuel injector o-rings, or PCV valve.... And, the crankshaft blade, Is that the timing plate? I ask, because there are several versions. Make sure your new one lines up exactly like your original.

Thank you. This is the part I purchased. I saw a couple of comments on the EP site saying it's an easy part to damage when maintenance is done so I figured better safe than sorry.

You recommend fuel injector rings and a PCV valve? This California-sourced truck has 104K miles and is very clean and well maintained...but I'll defer to folks who know far more than I do about wear and tear on these trucks.

Looks like you're off to a nice start bringing it up to par.

I always run a compression test on vehicles (usually before I purchase them).
Something to consider...
It's a good way to get a base-line before tearing into the motor.

Cheers

Fuel injector o-rings are like $8 for all of them, and I find the origionals get very hard and non-pliant after a few years. You might want to consider a fuel filter also.

x2 on the compression test, and easy to do with the intake off. Which by the way, there is a bolt in the far, far, far back left side of the intake that isn’t too hard to access, but is really hard to see, you gotta feel around for it.

I highly recommend having one of his injector kits on hand, just in case, if you plan on removing the fuel rails.

If I were getting a recently purchased 2.5 I intended to keep for a while up to snuff, in addition to what's already been listed, I would also look at and consider the following:

-Flush the brake fluid and inspect pads, if new rotors were needed then do the 315mm upgrade
-Inspect and replace any torn CV boots and/or worn ball joints and tie rods
-Upgrade the suspension bushings w/poly units
-Verify the shocks are in good condition
-Upgrade to a white ball transfer case shifter
-Get an alignment

It appears from the first post that OEM parts were purchased for the timing belt service.
Good call!

Cheers
 
Appreciate the replies.

Added to my list. Thank you.

Thanks. I'm going to have a local shop do the timing belt job so I'll ask them to run a compression test.

I'll focus on engine and cooling first, then tires, suspension, brakes and possibly a re-gear in another session (to spread out the $ spent). I've taken note of your suggestions for the latter. In addition to the white ball transfer case shifter, I'll be buying two shifter bushings since the shifter slogs around too much.

A rather important question? What brand timing belt did you get? Question goes for the water pump as well.

Five years or so back when I was refreshing my 2001 XLS, I took the advice of resident posters like Michael Brown and Toasty re: sticking with OEM. So this is the kit that's already in the mail. Thanks for asking.
