Looks good, I just bought a 2nd gen Montero and will also have to do this.

For those who's factory trim is still in tact, there is a simple trick to keep it from cracking. It sounds strange but a small coat of vegetable oil every now and then keeps this stuff healthy. I have a 1999 3000GT VR-4 (previously owned a 1991 3000GT VR-4) and they have basically the same trim. People would always ask me how I kept mine in such good shape... That was my little secret, odd, but it works.

Awesome video, thank you for posting!

If I lived out there I would donate my Montero for that... There has to be someone out there that can help...

Thanks! I love this thing so far. I have to dig through the forums and learn as much as I can about them.

So far everything is still working fine, minus a leak in the line somewhere.

I have owned my 2004 Montero Sport for about a year and love the thing. I never thought that I would end up selling it so soon. I was toying with the idea of getting a 2.5 gen Montero for a while but never got too serious about it because it is hard to trust that a 20 plus year old car was truly taken care of by a stranger.  It turns out that one of my friends decided that he is willing to part one of his. A bone stock (aside from brush guard), never seen a trail-all highway driven 1999 2.5 Gen. It has the winter package, leather seats, 146,000 miles, in just about the best condition you could ask for in a 20 year old rig. By no means is it in mint condition which is perfect for me because I plan to off road with it.

I am quite surprised at how comfortable this vehicle is. Even though it is 5 years older than my MS, it just feels better. The steering feels less "mushy", the transmission is smoother, it's quieter on the road, has all the fun 90's gizmos and gadgets, not to mention it is freaking awesome looking. I cant wait to get this thing to the trails this summer. I have a few things I need to do like take the running boards off and put rock sliders on etc. but otherwise it is in really good shape.

It wasn't really planned, but im excited for my adventures in this thing. Turns out that I also have a 1999 3000GT VR-4 too. So that is kind of cool!

Another thing that might help for the off road cooling is either changing to an electric fan setup or adding one or two single fans to get more air to move through the radiator. I had the same issues with my Montero Sport. I changed everything I could think of short of the AC condenser/evap. Things I went through before switching to the electric fans are as follows:

  • Change timing belt/Water Pump
  • Change thermostat
  • Coolant Flush
  • Ensure fan clutch worked fine
  • Ensure the fan shroud was in tact
  • Ensure AC fan was working
  • Got the cooling system pressure tested for leaks in the system
  • Change the radiator
  • Change transmission fluid
  • Replace temperature sensors

Everything on this list was done and everything checked out. I would never overheat in any situation except for off roading. I think it in part has to do with the stock fan only being able to turn as fast as the engine since it is belt driven. The electric fan swap fixed my issue since it can run full tilt regardless of engine speed.

Even so, I know something is still wrong because the stock setup should work. In fact, I still get a little warm during serious off roading or on mountain highways with long steep inclines such as I-70 which you will likely encounter in Colorado. But I only start to overheat if the AC is on. Even then it only gets to about 3/4 of max temp. Still too hot IMO. If the AC is off, no overheating no matter what I am doing. With that said, I am changing every main component of my air conditioning system. My compressor siezes up peiodically and is only getting worse. So since I have to change that anyway, I am going to change the evaporator, dryer, and condensor at the same time since I will have to get in there and will have the system empty.

It might be worth doing the conversion just to get you on the road again. I spend tons of money, and time trying to figure mine out. At least I am off roading again doing the fan conversion. If you haven't seen my write-up, here is the link:,572.0.html

Obviously my write up is for the Montero Sport, but the concept is the same. You just have to get the right size fans for your radiator. Like Shovel said (and I didn't do), try to go OEM with the radiator. Another thing to consider is rigging your condenser fan up on a switch so you can control it or a setup like I did with my electric fan conversion where it comes on at the same time as the water pump.

I live in colorado, so if you want someone to tag along for safety reasons, let me know. I would be more than happy to go along. At least that way you have someone to get you out of a tough spot if something were to happen. There is a decent size Montero group here and we are really good about helping each other out!

Good Luck!

More information about the TRE setup: The maximum ambient temperature the TRE pump can handle before damage occurs is 150 degrees C (302 degrees F) which is really hot. But those numbers are from their tech department, so it must be right.

I got some temperature readings while I was out on the trip. At highway speeds, my compressor stayed nice and cool at 82.8 degrees F. It was a cool morning so that helped. The hottest my compressor got was 178.9 degrees F while crawling when it was 90 degrees F outside. So that's not too bad.

I got some information about my specific pump too. The maximum ambient temperature the TRE pump can handle before damage occurs is 150 degrees C (302 degrees F) which is really hot. But those numbers are from their tech department, so it must be right.

So I put this setup through a pretty serious stress test yesterday and the locker/air compressor held up with zero issues! The trip started from my house at 6:30am and I didn't get home until 9:05pm. It was a long day. We were on the trail by about 9:00am and finished at 7:30pm.

The trail is possible without a locker (I did it last summer) but it seemed like I was getting stuck at just about every obstacle. I needed to either go around hard stuff, build the trail up, or run and gun it with momentum to make it through. It was very stressful and I was worried that I would break something.

This time was a whole different story. It seriously is night and day now having a locker. The only thing that limited me was my stock ride height, so I had to chose my lines correctly. But I was able to effortlessly climb everything without ANY TROUBLE! Given how easy the trail was this time, I almost felt like I was cheating. Seriously, that is how big of a difference a locker makes. I was able to use it on the fly, it always engaged/disengaged smooth. So smooth in fact, you cant even feel it engaged/disengaged whether you are sitting still or moving. The locker survived a good 10 hours of serious off road action and over 400 miles of normal use now without issue. So far, every penny was worth it.

On a side note, if people are in for a group buy, TRE offered me the opportunity to be a distributor. I will be able to get it at a better price with 10 or so purchases that buying individually. Just a thought. I personally would like to use it a bit more before standing behind it though.

This is really good stuff, man! Thanks for sharing it with us. Excellent write up too.

No problem, I am hitting a good trail tomorrow and will let you know if the setup grenades haha.  :-[

I am going to be hitting a pretty hard trail tomorrow which will put this cooling setup to the test. It is going to be in the low 90's tomorrow too. Hope all goes well!

On a side note, I am hitting the hardest trail I have done tomorrow. Might not be a big deal for some of you guys but it was challenging for me. It is a combination of two trails. Bill Moore Lake/Empire Loop. Last time I went, I didn't have a locker and I had to get a running start and just mash through some spots. It wasn't enjoyable for fear of breaking things. Now that I have this locker, I should be able to "crawl" up and methodically pick lines. I will get engine bay and air compressor temperatures while I am up there.

These days I carry a CO2 tank for airing up tires which can be used as a backup for your airlocker. just need to charge the system to get locker to work then leave it locked till you hit pavement or don't need it any more for that particular trail.

That's a good idea, what does your setup look like?

10 years sounds like a pretty good amount of time to me! I hope mine lasts that long. But it is Chinese. Worse case scenario, it dies, I work my way home without a locker and put a better compressor on. I guess I could buy heat shield material and attempt to protect it.
