Tune Up!

Try to do an internet search and look for a Jeep message board or local club. I know after buying my Dakota I found a few places that are fantastic.....things that these guys have been doing for years. Tried and true tips specific for YOUR vehicle. Alot better than getting generic info from a bunch of wash and polish guys!;)



Was that my "out loud" voice? Oh great, now I've done it. Let the :angry begin!!

Just did a quick search over at Jeeps Unlimited. Looks like the 97-98 Grands only had the "sock" filter that is a part of the fuel pump, and no external in-line filter. Theoretically, it should never need replacement.

Neat. I've never seen that before
 
Since I'm probably the only guy here with an ASE Master Gold Certification, I guess I can keep contributing to this thread...whoops, there went my "out loud voice"...



A cooling system is a "closed" system - it is pressurized and coolant is only allowed to circulate in the engine. It is not like motor oil, where some oil escaping past the rings or valve seals is considered "normal useage".



When coolant disappears, it means it's leaking somewhere. It's either leaking internally (like a failing headgasket, a flaw in the casting, a faulty intake manifold seal, etc), or it's leaking externally (most likely from a loose hose clamp, a leaky gasket, a failing waterpump, or a failing radiator/heater core). In any event, leaks are bad- they allow prescious pressure (say that 10 times fast) to escape from the system.



The pressure on your cooling system is very important to the boiling point of the coolant mixture. Water under pressure boils at a much higher temperature than non-pressurized water.



So, I would most definitely try to find the source of the leak.

im going to do that. Another question. How can not tourqing sparkplugs correctly affect the car? And also, i tested my resistance on my plug cables and it not commng up with anything, but for continuity im comming up with approx 1.6 , what does that mean?
 
Loose sparkplugs can quickly unseat themselves and literally "blow out" of the cylinder head. I saw a 1992 Chevrolet Beretta GT 3.1L V6 that did this - the owner changed the plugs himself, didn't tighten the rear plugs down enough and ended up tearing the threads out of his cylinder head.



I'm not so sure you're 100% comfortable with these repairs - it might not be a bad idea to have a shop do the work, or at least have a helper handy in case you've got questions during the tune-up. I'd rather be safe than sorry. :)



The 1.6 reading could be any unit of ohms. It could be 1.6 ohms, is my guess...do you have your volt/ohm meter set to the correct scale?
 
i think im comfortable, just making sure of a few things. Steve do you know hoe much it would cost or is there is a PCM upgrade for my zj. And is there any way to do it youself.
