What the heck are you suppose to do when the H3 reaches 100,000 miles?

My mechanic said check the book and it will tell you, don't know where it is and can't find anything on-line.

What has anyone done on theirs at or around 100,000?

I've only had the transmission fluid flushed so far.

Around 80,000 it needed a new belt.

That's about it.

 

Mine has 132K miles.

I would say that it really depends on if these are highway or off-road miles.

Transmission flush and fill (F&F). Did you change the filter when it was flushed?
Front & rear differential F&F
Transfer case fluid F&F
Power steering fluid F&F
Brake fluid F&F
Radiator F&F (if you have never replaced the radiator, you are in a minority)

Plugs and wires.
Shocks (just to be ****)
Headlight bulbs (they do wear out and get dim)
Thermostat

Once you do all of this, it should last a good long time. How long are you expecting to keep this H3? If you are going to sell/trade it in a year, why bother.

An analysis of the transmission fluid would tell you a LOT about the condition. Again, how long will you keep it?

The above items are maintenance issues. The wear parts (ball joints, brake pads) should be changed as necessary.

 

Pssst, "the book" meant read the friggin owner's manual, they usually are in the owners manual compartment that some folks used to call glove compartment.

If you can't find it in the truck, they are on line. If you need more help, let us know.

Basically what Djinco said. If you have an I5 H3, there are no plug wires and I wouldn't bother with a thermostat unless you have some issue that may be related to it.

 

it is in the manual

but yea what djinco said, new fluids all around, plugs, shocks should be done too.

 

congrats on hitting 100k!! It gives us younger folk inspiration!!
