88AMComanche

Is it crazy to have 202,000 & still drive it everyday? Theres no overheating isses, although with engine warm and sitting idle at a redlight,my oil pressure is about 16 .. Been at this for years. I'm considering going up to 15-40 next oil change.

So it just paints on like a thick paint? Floors arent too pretty. Sheet metal,framework,screw heads etc .....was hoping for something that would hide the bare floor. But I will consider this considering Rockauto wants over 100.00 for just a vinal floor.

Since my carpet is ruined now & I will remove my seats to get the rest of the carpet up. It was heavily staiined anyway .....I'm considering leaving bare floor but its a bit on the Ugly side even sprayed with the bedliner mat stuff. - Are there any places that sell a vinal floor in place of carpet for comanches? even if its a cherokee flooring & I could just cut the back half off for the right length.

Mine used to have that same problem. Its the fat seal for the blower motor. Mine had a small leak rigtht at the bottom. I got a tube of all purpose indoor outdoor clear sealent from home depot & globbed me a nice clear stream of it and it hasnt leaked since.

Its not the accordian type rubber hose type thing thats used to cover the wires. Mine has those on both doors. - The holes I'm talking about are on the Outter side Cowl pillar I guess? Its about 5 inches in front of the doors if you took the fenders off. Theyre right next to where the antenna goes into the truck. The fat plug where it enters into the cab. - My truck is missing the big plastic wheel well cover. The one thats like 3 feet long half moon & keeps water in the wheel area instead of slinging water all up under the fender.-Mines missing that. .maybe thats why its making it up to the 2 holes under the fender & trickling into my floor.

I'm gonna seal around my antenna rubber where it plugs in under the fender ...........ALSO while I was leaned in there looking, Just above the antenna plug hole but closer to the hinge area, there 2 big holes. dunno what they are for. Looks as if maybe they take a big rubber plug maybe. If you look under the passenger wheel well & can get your head kinda in there you can see the antenna plug ......then 2 big holes,unless yours is plugged by the rubbr/plastic capoff plugs? I just know water is trailing in almost at the floor back behind that side kick panel next to the lil light under the pass. dash. Theres about an inch clearence under the plastic panel & I watched a trail of water trickle from behind it to the floor. - I HATE water leaks. Ive already cut out my front carpet. now after all this rain,my carpet under the seats is soggy too so my back glass or sunroof is leaking. -Whats with the baby pawder trick?? something to find a leak?

I have SOAKED floors. I stopped all leaks when i bought the truck 5 years ago. - I just went outside now since its pouring rain to see where its coming in at . The Passenger side side kickpanel below it where it meets the floor theres 3-4 streaks of drip coming in & puddling in the floor. What could be there that would allow water to leak in when the truck is parked just sitting there??? Isnt it solid frame area there between the door & the front wheel?? Somehow water is coming in and dripping down from under that plastic side kick panel. Any ideas??? ALSO The back window Top corner is leaking. I think I camn buy some of that leak sealer for that,where ya pour it where you think its leaking & it finds the leak & gets thick & dries. But the side kick panel plastic pice I am lost on where it could be coming from. Anyone please throw any possibilities at me. tyvm in advance.

Hi-Had to post new thread since all old ones were deleted. I have my NEW overflow water tank finally.........and bought the hoses I need in 5/8 size. Problem is...........the INLET tube on the water tank is a bit smaller than 5/8 & the Outlet (bottom) tube is much bigger than 5/8.(its the exact same size as the entire 5/8 outyside hose size) .Does any one know what size Hose goes to the INLET(top) AND the Outlet tube(bottom) on an 88 Comanche coolant overflow tank? plz let me know if you know because I am now stranded with no way to get to the store but will catch a ride tomorrow and hoping to find out before hand so I know what size hose I need. Thanx very much in advance.

Okay thanx- What happens if its filled full? thats what Ive always done. Now that I'm thinkin about it,it would build lots pf pressure that way.

wow that sucks. but they know when we need something we;ll pay what they want usually,or someone will at some point.

I have the 88 Comanche manual pdf, but yeh ,its exellent for reference

reaso9n Imasking is because I have a new tank on the way & have no idea what hose to buy for the bottom nipple thing that goes out to the water pump

Inlet side is 5/8 hose , then what is the bottom line going out?

Thanx Comanchefan. I just may have to fall back on that. That "T" pice (center bottom) sure looks handy & very similar to what I need,except it needs to turn to the other way instead of toward the camera. Thanx though,this May work.

Hi- Another issue here: Someone bypassed the heater control valve on my comanche 4.0 so here s the layout of my hoses. From water pump to Heatercore Intake , from heatercore OUT to radiator Overflow tank(next to pass hood hinge) From overflow tank to waterpump intake line. here's THE PROBLEM ........ I need a hose to from from Firewall/heatercore to the Overflow bottle which is close to the heatercore line. . its 5/8" hose . try to follow this part ........it comes OUT of firewall about 3 inches,goes UP about 3 inches,then goes LEFT about 3 inches to go into the overflow bottle. - I can't find a hose like this ANYWHERE. .a 5/8 hose that 90s ,goes a few unches then 90s again. - ... SO,reckon I'm stuck using connector fittings? its all because there IS NO heater control valvce thingy that the hoses connect to.it was bypassed long ago.

Ty for the reply - I ended up buying one off ebay last nite a few hours after posting here. It was 40 bux free shipping but its new & yeh overpriced, but I need it. -ty though.

Help?

88 Eliminator 4.0 5 speed ...I have some make shift old water hose 5/8" with extra hose clamps that I put on years ago & Ive never finished doing my coolant system the Right way. So Ive always had a micro slow water leak. Now- I need a WATER REVERVIOR tank & can't find one. Anyone know where i can get one for 20ish or so dollars? PLUS- one day I seen a 91 cherokee that had the same setup (water reservior tank) as my comanche .......except they had some weird 5 valved junction water tubing of some kind which really made everything look clean & tidy cuz all hoses connected to that multi connector thing. I'm dying to know what this juntion type mutitube thing was so I can get one. Anyway,I need a water tank for my Comanche.

silly idea........But.......What about putting a 2 way On/off valve just before the heater core? That way during the winter just turn the vale to ON, & sometime before summer turn the valve OFF .same purpose as a HCV but it would be done manulaly & with almost no chance of it going bad. I could handle popping the hood once every few months & turn it on or off. :banana:

Last night I started my truck & it revved to around 2700 rpms so I quikly put it in reverse to get moving,not thinking its gonna rev like that the whole way home. I THOUGHt it wold idle down once it warmed up maybe ......Its stayed at almost 3000 all the way home. Needless to say it ran a bit hot once i stopped. Its done this a few times in the past but never stayed high like that & never quite that high. Would a Map sensor cause this? Is there a shortcut way of finding out what causes it? I don't have an Ohm meter/tester. Lil lost on where to start even. Will check messages tonight if anyone has any solutions.

But whats Open system mean? I thought about eliminating bottle tank but would still end up with hoses so .... Now I just wanna simplify it down & use as less connections as possible.

I hate my hose setup. Its ratty, too many hose clamps, too many pieces of hose too. There WAS a steel tubing piece that came on 91 or 92 Laredos without HCV where its like a junction point where all the hoses back by the water reserviour tank all met up at that 6 point steel 5/8s tubing piece, but ive giving up on finding what its called or where to get one. So If anyone has any ideas or suggestions on how to tidy up my mess of a cooling system hose setup, Id greatly appreciate it & consider it. I seen pics of a dude that made his out of plumbing Pvc & it looked sorta cool. Very tidy. but also ghetto too sorta. But I'm open to anyones ideas. I have No HCV and just 2 hoses going from engine to the heater core, then 2 going to the water reserviour coolant bottle tank thing, then back to engine. thanx in advance.

I just nosed the truck down in the ditch & started it up & slowly removed the temp sender,lotta air,then gyser of water solid.... Now it runs at 200 steady,thanx

I tried uploading a pic but can't seem to do it. Picture a Heater control valve....but remove the valve & you end up with a multiple fitting connector type thing that the hoses all connect to & and allow water to pass thrue ......THATS what I need to find out what this thing is that I'm looking for. I have no HCV , but do need the multi port plastic connector thing,just without the HCV on it.

UPDATE: I swung into my mechanics shop yesterday.....well, the one I USED to go to since i was going right past his shop. He listened to it & said it sounds like its coming from the IMAP sensor??? He pointed at the long fat black plastic tube that goes from the air breather up to th etop of the engine, and ...I'm pretty sure he said maybe the imap sensor is going bad. ...at that time it did sorta sound like it was coming from the fat black plastic tubing area going to the top of the engine. It makes like a random spuratic almost duck sound for about a half a second then it sgone,as it does it the rpms will drop/lag for a split second. I THOUGHT it was the PS pump,but now I'm not so sure.
