    T-Shirt weather here in CT today... suppose to be even warmer tomorrow! It was actually warmer at my house in NH today if you can believe it.
    Still working on momma's Pacifica... the oil cooler is still giving my the finger at the moment, I'm about ready to shoot the S.O.B.
    I want to meet the genius who designed this P.O.S.... especially the attachment bolt which doubles as the oil filter attachment thread. No flats cut on the outside for a wrench, and no Hex key cut on the inside either for an allen.

    Can you put a double "nut" on it to back it out?

    Yeah, but I hope you had the R/T and Tank inside! Oh, and the wagon too.

    Hail damage is NO FUN!

    Luckily I have never seen big hail here, not to say it won't someday. It has snowed on the beach before.
    My buddies R/T vert got caught in big hail, what a mess it did.

    Tried that... all it did was sharpen the threads as the locked nuts began backing down the threads. It was actually reworking the threads on the nuts.
    I tried every trick in the book, even an impact gun with a socket and a rubber washer. Without a replacement in hand, I wasn't going to push it any further than I needed to. Heck, if double nutting it didn't work, thats telling you something right there.
    Either way, I flushed it out as best I could with some 40 - 60 psi water pressure, and then back-flushed the heater core while I was there. It appears to be operating well enough now. We'll see how it behaves during the ride home this evening.
    If nothing else, at least the engine got an oil and filter change out of the deal. :D

    You don't suppose its a left hand thread, do you?

    Nope, no left hand thread... already verified that.
    Now that I'm all done for now... I was poking around on Google and found yet another image (different make & model year, different engine size), and this one shows a Hex cut deep inside. This is probably what I have, but my Hex Socket was to short to reach. I couldn't see that deep in the hole laying on the ground. All of the images I had seen previously showed a Hex cut right from the face, so I was assuming mine was the same or didn't have it... not that I didn't try of course, but my 12mm Hex Socket is only about 1" long.
    well, if I have to go at it again, I'll pick up a long 12mm hex. Still, double nutting should have done the job too, but that didn't happen.

    Hope the flush took care of the issue for the most part... I had to chuckle with the PSI you used. Hope that New junk can handle that old school fixing !!!!!!!!!!! Keep us posted... :)

    Individual component flush worked great for a few of days, but apparently there's a lot more junk floating around in the rest of the system. I'm going to do a complete systems flush Sunday morning over at the shop.

    I'm Not 100% sure, But I thought those were a flow threw system? Meaning that they have flow all the time, and the Blend door is what cuts the heat off? I was under the impression that these cars didn't have a heater control valve anymore?

    But if that's the case.... Tap on the blend door motor and see if it will move? Providing you can get to that one? Some of them they just bury....

    Hey Bob

    When I started this the Oil Cooler was only flowing about 5%... it had a lot of crap in it. I went at it a couple of times and did finally manage to get it flushed out well enough... 90% anyway. That's why I wanted to get it off the vehicle, so I could clean it out 100%.
    The heater core itself had a little sludge in it from poor circulation due to the oil cooler, but it flushed out nice and easy.
    The heat seemed to be working fine after that... once I got in it and started driving anyway.

    Momma said the heat crapped out again, so I took it out this morning for a test run. The heat was working fine once the engine got up to temp, but it started blowing lukewarm air as soon as I hit the first stop sign. I left the intersection and it immediately started blowing hot air again. Shortly after that it started fading again and eventually began blowing cold air only.

    I believe your correct about the Blend Door... and now that I think about it, momma did mention once that only the drivers side was blowing heat one day.
    I like the Charger better... Heat ------ Cool, just slide the lever to find your comfort zone.
    I think the Pacifica has 2 or 3 motors for Mode, Blend, Etc... all controlled by a Puter somewhere. Like they say, the more you complicate the plumbing, the easier it is to stop up the drain.

    Oh well, fix one issue, find another...

    I know what you mean... About 3 weeks ago I worked on a Jeep Wrangler Sport R.H. Drive that the parking enforcement folks brought in. The somewhat same compliant no warm air. open the hood, felt the heater hoses, both being hot, opened what would be the regular drivers door. smacked the blend door motor, cycled the hot and cold control know a few time. and the jeep has not come back yet ...lol
    Some times the simplest thing work?????

    I'll try to "recalibrate" it in the morning... hey, you never know right Drunk

    I did a recalibration on the actuator motors today, and I'm 90% positive there's an issue with at least one of them, so I'll check that out later.
    Be that as it may, I still had no flow through the heater core today... at least not while idling. Once you hit the gas or rev the engine, you get a little heat, but that goes away as quickly as it came. My initial thoughts concerning the clogged oil cooler were still weighing heavy in the back of my mind. I had it flushed out pretty well, but I was thinking that it may have plugged up again since. That said, I jury rigged a bypass around the cooler, and took it out for a test run. All has been working fine since... I'll give it a couple of more days to be sure of course, but if all is still well after a few days of driving, then I'll order some new parts and fix it right.

    Now you got me wounding if it has a flow issue or if someone installed maybe the wrong thermostat? Run your Temp Gun and check them temp's?

    Engine temp has always been right where it should be, no problem with the thermostat, just a plugged up oil cooler. It's been working perfect ever since I bypassed that P.O.S. Disc style oil cooler they have installed at the top of the oil filter. I'm headed to NH this weekend, but when I get back I'm going to plug the old cooler and bypass it permanently. I'd like to remove the thing altogether, but the oil filter has to attach to something, and I haven't seen any "Cooler Delete" plates available. You'd think that someone would have made one by now considering all the trouble people have had with these stupid things corroding, leaking coolant into the oil, and vice versa, plugging up causing heating issues, etc.
