#76 of 349 SYNTHETIC OIL
Aug 19, 2007 (8:24 am)
Read this in the Sunday's question/answer auto section Chicago Tribune:
Q The owner's manual for my 2007 Jeep Grand Cherokee with a 3.7-liter V-6 gas engine recommends 5W-20 motor oil. The manual isn't clear whether synthetic oil can be used. Can it?
A Chrysler says that under terms of its warranty synthetic oil can be used in only its diesel Grand Cherokee, not in any of its gas versions.
You think this includes the Jeep Wrangler V-6 also? If so, why? I though all auto companies favored less friction via synthetic oils?
#77 of 349 '93 YJ - Best, cheapest, and/or easiest full-length axle swap?

#78 of 349 Exhaust air tube.
Aug 21, 2007 (11:23 am)
I recently acquired a 1989 Jeep Wrangler 4.2L and took it to Merlin's to have a new exhaust put on. When they connected the air tube to the exhaust manifold they used high temp rubber hose, which of course melted and blew. I took it back to them and they did the same thing with the same outcome. What are you supposed to use to connect the air tube to the nipple on the exhaust manifold? Any ideas?

Did you ever get your problem resolved? I am having the same problem with my 95 Jeep Wrangler. I have to wait for the auto shutdown and fuel pump relays to click, when the clicking stops the Jeep starts. The cold and wet rain make the waiting time longer.
Thanks for your time.
#80 of 349 Turn Signals/Backup Lights Problem
Sep 09, 2007 (5:39 am)
Have a 1989 YJ that my son at college (50 miles away) Turn signals were out and I replaced all questionable bulbs and replaced the fuse. Later noted in manual that backup lights are on same fuse. I tested and backup lights are also not working. Last year, my mechanic fixed backup lights by repairing the ground wire.
Before I have my son drive back, should I have him change the backup bulbs? Any suggestions?

I put the weber carb on and you were right runs like it is brand new can't believe the difference. But did create a new problem. It seems as though when re attaching the vacum hoses I missed the hose that engages the 4 wheel drive. Does anyone have a schematic of the system. Found nothing in Haynes book. Still waiting for the Chilton book to arrive. Again thanks boobah for the weber carb solution I couldn't be happier.

Does the "4-wheel drive" hose connect from the carburetor to the front axle? If so, then the hose may not be necessary. The vacuum-operated front axle disconnect can be circumvented by placing washers in the housing to keep the yoke connected all the time. This is not a problem because 4wd is connected only when the transfer case is connected. IIRC TJ's (and CJ's) do not have this disconnect system. It was used on YJ's in an attempt to decrease wear on the front differential, but was found to be unnecessary.
There may be a post in the main Jeep Wrangler board relating to this fix, or you can search the web for the YJ front axle disconnect repair.

I wouldn't bother if the bulbs are functioning.

I'm not sure I understand the auto shutdown and fuel pump relays??? My 95 Jeep started having problems starting about two weeks ago. It used to start right away, but now I have to crank and crank, and crank it to get it to start. Once it starts, it runs fine. Funny thing is, when I shut it off, it will restart if I try it within about 10 seconds. I've replaced the fuel filter and added injector cleaner into the gas tank, but neither of those things has helped??? Any ideas or suggestions???
