90 work truck

Yes, I saved the old one as a spare the sleeve from new one is Gates(sold by Napa) #061025

Yes

An update. . made it two blocks and it (chirping) started up again Drove it to Napa got a new belt (premium one $42. !!) I've been bit more than once chincing Must of contaminated old one with coolant when I changed water pump (spraying lubricant on Idler pulley bolt, while troubleshooting, probably didn't help) Long story short Quiet as a lady of the night in church.

Thanks jtrux got all the parts from Dirk at dpg off road (Old Man emu front coils, spacers, shocks, JKS track bar, upper & lower control arms, sway bar disconnects) Rear leaf pack is sold by Rusty's Canadian MFg. It's advertised as 4'" getting closer to 3 tires are grabber at2 215 around 27" next time I need tires (these only have approx. 10,000 miles on them) Might go a little larger 30"ish just for a little more clearance (snow, don't go off road much) want to keep my turbines don"t want to re--gear Back on topic I think I might of taken care of the chirping, ( I hope for good) put a little dawn dishwashing soap in spray bottle with hot water (thanks to posts read here) sprayed down belt then carefully held 3m abrasive pad on running belt, repeated 2 more times. Quiet now, time will tell

This is the old one New ones on the truck but doesn't have a large enough flat area to accept the larger washer that surrounds the reducing bushing

Thanks I had read that too, I took a 3m abrasive pad and cleaned off the belt(no cracks, LOOKS in good condition) I don't mind buying a belt Just trying to avoid throwing more parts at it Hence the wondering about the bolt being threaded, and if theres suppose to be a washer between pulley and bracket because it also quiets down when I spray lubricant there?

I've been having cooling system issues lately, the last thing to go was the water pump(leaking from weep hole), before replacing it everything was quiet, Did some looking and and thought it was the idler pulley was where it was coming from, replaced it with one from NAPA (gates # 38042) I've adjusted the belt from fairly loose to snare drum tight, and everywhere in between. The old pulley/bearing had a dust cover/washer looking piece(approx. 1.75" Diam) around the bushing the new gates didn't, gates came with the pulley with bearing installed and the reducer. The curvature of the convex side of pulley won't allow use of the old one. I can get it to quiet down for a few seconds by spraying a penetrating lube.where bolt goes into bracket & bolt head, it will also quiet down by spraying water on belt, till it dries starts right up again. Does anyone know if there is to be a washer between pulley and mounting bracket that I might of lost? Also it seems odd to me that the bolt is threaded its whole length and not just where it goes into bracket. Hoping someone has a solution before I pull the cord on the cannon and go buy a belt

I wouldn't change my factory bench, in decent shape, I figure if I ever needed to I can re-foam, got 2 hunting buddies (dogs) and they fit just fine

The stock ones worked for me Hope this helped

Fwiw 3 years ago when I was looking for an mj the closest "decent" one was in Madison, Wi bout a hundred miles from me, everything closer was Rusted out. Had a lot more miles,(184,000) 1990 4.0 auto 4 X 4 (Did need to put in new floor pans) Otherwise was pretty clean. I wasn't aware of this site then or its classified section. I think I paid a fair price ($2500) I know I didn't steal it and I was tired of looking (probably have put another $5000 into it, lift kit, tires Deferred maintenance, bed liner didn't NEED most of what I did, kinda like when you buy a house something's you just do to make it your own. And don't expect to recoup those costs, (no plans on selling her though) Hope this helps

So 1.5 more ohms made a noticeable difference?

Thanks Much Eagle, AGAIN GREAT EXPLANATION thanks for the picks!

Thanks Eagle, GREAT explanation, so correct me if I'm wrong the tube that goes to overflow from my Mac's Pressure bottle needs to go down to the bottom/lower part of the overflow bottle? Can't see the fluid jumping up to the inlet near top of overflow? That "slight suction" wouldn't be enough to bridge a 4-5" gap? Also command sense tells me the top of overflow bottle should be close in height of the Mac's bottle? Was thinking I'd have room for it under the Mac's(in front of blower motor) Experience with aquariums says that an accident waiting to happen, with all the fluid above it siphoning down into my blower motor! I would need to move a lot of vacuum lines relays etch to mount it over by the airbox on the driver side inner fender. Did some Google searches and looks like guys are making these from everything from High energy drink cans to spent whiskey bottles. Does your overflow bottle have 2 inlets or a hose inside the bottle?

I used this very happy with it they make two different types use the harder of the 2 aromatic vs aliphatic I used the softer one on a Dakota I Had And it faded and flaked in a few places. Did the Interior floors, bed & ladder rack in a dark grey and body lighter & flares black only 2 years old but holding up great(on "old Paint" my MJ Hope this helps http://www.grizzlygrip.com/Catalog.aspx

Did some more searching here, might of answered my own questions(your previous posts did) looks like a 2.5 overflow bottle is in my future, as well as a radiator. I like to try to know why/how things work, and I am under some misconceptions about the cap. And doing it the way I have been filing it (the mac bottle) 1/2 way at cold , I might be allowing air to enter system when sitting as the inlet to the tank is above the coolant level (when 1/2 full) Would of thought between the pressure of the system ad that being the incoming fluid it would of been good, anyhow worse that I can see is adding a quart or so of coolant to the system. I'd rather not have to run a hose all the way over to airbox if I don't have to, I've relocated my vacuumed canister under the pressure bottle bracket and have a little room between the Macs bottle and the fender wall, going to look into there first. Where have other people done for over flow bottle that went with the aftermarket tanks? Thanks, Mark
