#257 of 385 Replacing a water pump on a V6 1991 trooper
Nov 21, 2008 (5:52 pm)
Need Help ASAP
Hi I have a 1991 V6 Isuzu Trooper Auto. I need to replace the water pump cause it is leaking. Can someone tell me what size star socket I have to get to take off the bolts holding the water pump on. I have not done this on a trooper before what is the process and do I need any special tools. Also do I need to replace anything else ( hoping to use the belt cause I think they are pricey) while I have the pump off? Any help would be appreciated.

Not sure of the size of star socket,probably a 12 mm. Drain,antifreeze,Remove hoses, remove radiator,fan stroud, fan and pully.Serpenten belt removed. Air condition and power stering pump and brackets move out the way.Remove all bolts and nuts..Tap on pump with rubber mallad.Match pump to new one. Clean all mating surfaces real good.And assemble in reverse with new gasket.
Get a manuel if in doubt.Good luck!
#259 of 385 window regulator - plastic rollers
Nov 27, 2008 (7:58 am)
Is there a replacement part avaialble for just the plastic/nylon rollers that the regulator arms pop into? These rollers roll in the track that is attached to the bottom of the window in my 1996 trooper with power windows. One of mine are cracked and it makes it so one of the arms pop out. If it is an entire unit, can you suggest a source for the entire unit.

the diagrams do not show how it comes appart, it only shows it in parts.. I dont know if it was unscrewed from the tank as a whole or if the 8 screws were what holds in on.. they are not usable.. they are rusted so bad a screw driver will not bite on them..

My 1990 Trooper runs fine for a while, and then it periodically just dies. All of the warning lights come on, and it's like some one just flipped a switch and turned it off. It has power to all circuits, except there is no spark at all to the spark plugs.
There is no pattern to this that I can discern. Sometimes it runs for three or four months before it does it. Sometimes it's a day. Sometimes it won't start for a week or more, and other times it will start back up in a few minutes. It does it in dry weather and wet. It does it when it's hot and when it's cold.
I have replaced all of the relays and the coil.
Anyone have any idea where to look next?
#264 of 385 91 trooper starting problem when warmed-up
Jan 07, 2009 (5:06 pm)
I have a 1991 trooper with 6cyl. It will start ok in the morning and run right, but after it gets warm, it is hard to start again. I normally just use starter fluid to get it going, but even that is getting hard. When that fails, I can just let it sit for a while and it will start and run ok ... till i shut it off again. I tried replacing the fuel filter, but no difference, and I have the error codes but can't find what they refer to.

Did you ever receive any replies? I have two 2002 Troopers, and neither seems to burn too much oil. Have only had them for a year or so each, and both have less than 50k miles. This is a concern I have seen raised before, with no clear answers as I recall - other than check the level regularly.
