Hi All, Just wanted to say a quick hi. I've been reading through the archives for a while as my member ship was getting approved. I just bought an 89 Montero LWB this last weekend that is in amazing shape. It's my first one, so I'm in the process of going over it with the manuals I found on this site. The initial goal is to get it caught up on all of the prior maintenance and enjoy it as a daily driver. Short list of initial items: Oil Change Trans fluid drain & Fill (Mitsu SP3 Fluid) Coolant Flush Fuel filter - OEM Chassis Lube
This is still the most thorough site for Monteros.
Your Monty is super clean, makes me a little jealous.

Hi Russell, Thanks for the welcome. It's surprisingly clean and the build quality is impressive too. I have some work getting some of the previous work resolved to return it to factory. So far I've just been going through the maintenance items with the FSM. Cold compression was decent @ 130PSI on the 2 cylinders I checked, I'll get the rest when I replace the plugs.
I've ordered the OEM pan gasket & filter for the trans and the OEM radiator cap. The SP3 fluid I picked up from Mitsubishi dealer is ATF SP-III (MZ320200), which I believe is different from what was originally specified for these. I need to do some research on what is the correct fluid for the transmission.
Also, the PO replaced the radiator with on that has plastic tanks and I believe aluminum fins. I'd like to go back to the factory design, but need to post a wanted ad for my increasing list of items. I'm running my 2nd batch of Blue Devil cleaner with distilled water in the current cooling system to loosen all the rust up. I still need to find the block drains so I can make sure that area is clear of any deposits.
So for now, I'll just keep driving back and forth to work and let that coolant flush do it's work.
Cooling is important. When you find a radiator, look at the depth of the top and bottom tanks vs. the depth of the core. For some reason, Mitsubishi used 2 row cores with the tanks able to handle a 3 row core. I don't know if this was just a North America thing. Anyway, you should be able to have the 2 row core replaced with a 3 row core. This should give you somewhere about 30% more cooling surface. Along with more fluid capacity.
