Would you reccomend fluid changes?
1993 XJ 4.0HO w/ AX-15 and 165K on the clock.
Don't know if any of the fluids have been changed by PO. What would you do? Thanks! T |

Well, I remember someone saying its not good to change some fluids if you have high miles and don't know if they have been changed because it could cause more damage than leaving them in.:brickwall:

Drain it run some water through to clean any rust out then refill with fresh..it'll cool the engine better..The question is when was the last time the PO changed it never more then likely..
Also if it's a used car I would also do a complete tuneup...cap,rotor, plugs, wires, air filter, fuel filter... These are things I do anytime I buy a used car.. |
You said not to flush the tranny or cooling system - i understand the tranny just was confused why not on the cooling system..

Just don't FLUSH them. Your seals and synchros and chains and teeth have become best friends with the deposits left behind by our old fluids. If you flush the deposits out, the components get separation anxiety and get very, very angry.

i work at a jeep dealership and i personally dont think it matters with the aw4. that is such a tough trans. We have had guys at are work flush their trans with a 150000 and to his knowledge never had a flush and it actually made his shifts alot crisper.
|
its all preference on that trans
|
i didnt feel like flushing mine and my trans pan was leaking a little bit so i jus spill and filled it, i also changed the trans filter.
|
Are transmission guys at work have been doing this for a long time and niether of them have ever had to rebuild an aw4.
