    eater Core questions (yeah as always)

    Surely the unit holds far more than a cup of fluid. I was able to get maybe 3/4 cup in. Again air, water, flush passes without restriction which makes me think the unit is identical in design to a radiator which allowed for fluids to bypass the entire radiator when clogged. Does anyone know...

    Followup. Put everything back together, refilled as needed, parked on incline with car at full temp to make sure to bleed out any air. Hose temps around 170 with just about 10 degrees difference between in and out with heater on, fan at full blast, outside temps around 55. Vent heat is right...

    Actually blocking the outside air door would increase the heat level if the blend door was faulty. I don't think it has anything to do with the blend door, the problem would be evident during summer as well with the A/C unable to cool the interior when not on recirculating.

    To further make me think the core is hollow across the top and this acts as a bypass I was using some clear tubing for the flush so I could see what was passing through. With both sides of the core attached to hosing which I ran up to the hood latch so they are clearly higher than the core I...

    eater Core questions (yeah as always)

    So I had my radiator replaced last year and since then the heater core has clogged a few times. Clearly the guy doing the radiator did not flush the system fully or correctly. No problem, pull the hoses, backflush and we have heat. This year however I again had very little heat the other day...

    Coolant problems, no heat

    I'm the original owner, vehicle has been taken care of. I went to a "radiator shop", a place that only does radiator and cooling system work expecting them to know how to do a proper job. Dealership work is just way overpriced for normal vehicle work. I brought it up with them prior to showing...

    Coolant problems, no heat

    So flushed it out, again, and yeap it was full of this junk. I'd say there was a good 2 tablespoons of this stuff. It came out in tubular form as if a mold of the inside of the heater tube, slightly smaller. My bet is the heater core tube itself is smaller than the tube on the firewall leading...

    Coolant problems, no heat

    HOAT, bought from dealership and mixed, not the pre-mix. Yes distilled water. No reason to change out wither the thermostat of WP since cooling works fine. I have no doubt had I been able to actually do a real flush that the old radiator would have been fine, at least for some time with the...

    Coolant problems, no heat

    Some background first: Engine kept overheating then it wouldn't. Seemed to have no pattern as I might be able to drive 60 miles on a very hot day with no issues then on another day I couldn't go two blocks without it overheating. In checking the radiator out I found a small crack that many...

    Rolling marble sound from rear area

    Well I've not heard the noise for awhile, granted I haven't really tried to force it by making hard turns. I put a very strong rare earth magnet on the body, under the rear end. There is a U shaped body reinforcement that goes from side to side and I placed the magnet towards the passenger side...

    Rolling marble sound from rear area

    There are a number of areas that I could use that expanding spray foam far easier than a magnet or trying to access them for looking around. Can anyone think of reasons not to use this spray foam? I am thinking of the areas such as the lower rear door panel or the cross frame body cavities would...

    Rolling marble sound from rear area

    Did stop by another dealership to quickly ask the parts/service guy if he could think of anything which he couldn't but he told me a story about another customer. Older gal would bring in her Cherokee because of a noise in her driver door. They would take off the door panel and find a dime. Few...

    Rolling marble sound from rear area

    This would mean the dealership did something intentional because I had a factory hitch so all they were to do was to inspect it and certify the recall was done. Inspected the bolts of the hitch and if they even tightened them it doesn't so, there are no socket marks at all. Everything...

    Rolling marble sound from rear area

    One thought I had was if the Jeep has the fuel pump inside the tank like Dodge does and if it was somehow loose but the tank is plastic which would be a deeper thunk than this metal on metal sound. My biggest concern is if this is mechanical is it something that is broken and while driving...

    Possible Recall 2002-2007?

    While under the rear end trying to find the source of a noise (see other post) I noticed what they did in terms of the recall when you have a factory hitch already installed. they stuck a label on there saying don't leave on the ball mount if not towing something. Took them more time to put it...

    Rolling marble sound from rear area

    Well took off the rear panel and nothing in the reachable areas. It has a reinforcement about 4 inches from the bottom that keeps you from seeing the full area however there are a few slots cut that you can look through and I couldn't see anything or see any indication something had rolled...

    Rolling marble sound from rear area

    Factory hitch so yes it's open on either end. My thought was maybe it was something that just couldn't wiggle out the end holes. Magnet should catch anything if they are strong enough, they may not be, strongest that Lowes had. I've got some additional rare earth ones to try but I'm thinking I...

    Rolling marble sound from rear area

    This has just recently started and the only thing that has changed in my Liberty is Jeep did the hitch inspection due to recall. When making a somewhat hard left or right turn I get a rolling marble sound coming from the rear end somewhere. It's clearly metal on metal sound. Sometimes this...
