Hopefully it's the simple fix I think it is and not genuine rebuild time.
OH, BTW - my advice on that is to just remove the broken off pieces of the snap ring from the valve body, and just leave the (broken) snap ring in. If I'd have done that, I would have been done several *hours* earlier, and a lot less angry. See, the parts of the snap ring that break off are the ends, where the notches/holes for REMOVING THE SNAP RING ARE. Want to make a guess at how incredibly difficult and frustrating it is to remove a snap ring, in a recessed hole, when it has no tool holes?

That’s handy. I had the factory service manual, but it was surprisingly annoying to find the torque specs and tightening sequence.

So I had to drive my car around today and it occurred to me, does the lockup clutch engage with overdrive disabled? Am I potentially loving up my converter by driving around like that? I got paranoid and did the rest of my driving in a very burn-and-coast style to avoid cruising, am I overthinking it?

No, it doesn’t lock up, and no you’re not hurting anything. There’s a bit more heat generated, but on. Your cop car, it won’t be a problem. The transmission is designed to have the OD turned off when towing, for example, or going up steep grades, if I’m remembering the owners manual correctly.
Should be fine.

Heck, check the owners manual and see what it says. They are available online.

Alright I've googled like i should have and it does seem like it only locks up in OD, so that's good to know.

I've never driven a car without lockup, it's really annoying waiting for the converter to load up when I go from coast/cruise to accelerating.

E: Also I've realized that if I don't do the heater core while it's down for the transmission job I will hate myself forever. Ugh.

Lockup converters are sometimes looser when they aren't locked than a traditional converter. But yes, it's a thing.

The cooling fan stopped coming on at high temps on my 1998 Grand Marquis, so our temporary solution was to just leave the AC on all the time and thus keep the high speed fan going. Then that speed working and the car overheated for two seconds before it was shut off, allowed to cool and drove home (it only overheated a block from the house). It's been a series of cooling issues with this car that I thought were remedied when I replaced the intake manifold.

Now it cranks but won't start. I checked the pigtail that connects to the fan, and one terminal has a burn mark that corresponds to a burn mark on the fan's terminal. However, the fan still works if I wire it directly to the battery.

I can hear the fuel pump priming when turning the key, fuel shoots out of the schrader valve on the fuel rail, and so far 7/8 spark plugs have tested OK for spark. The COP boot for the last plug in the rear passenger side just broke off inside the plug well and I want to kill myself now.

All fuses test OK. I havent tested any relays yet but they look OK, visually.

I have a cheap BAFX OBD2 bluetooth scanner and, using Torque, I can connect to it but it cannot talk to the car's ECU. The OBD port has power. It worked about a year ago so I don't know if it's a torque update causing it to not work or my ECU is hosed somehow. I don't have the money to get a scanner loaned from the parts store right now.

Any tips would be much appreciated.

Word, I downloaded it and...still no communication. The ECU fuse and relay tested OK, and the CEL stays on when the car is on, so it sounds like the ECU is working? I don't know why it won't connect.

I guess next I could check the voltage and resistance of the fuel injectors to see if it's actually getting gas.

Well gently caress. Was sitting in a parking lot waiting to drive to my cousins, was parked for line a half hour. I looked up and suddenly my coolant temp was pegged and the warning light was on. Got out and the radiator fan want working, even with a/c on full blast. I panicked and VERY GENTLY drove it the mile to his place to get some airflow through. After I shut the car off, I turned the key right back on to pull Torque up and it was immediately down to mid gauge, app reported temp of 110C.

Did I just gently caress my engine? Wtf.

Shot in the dark, but do you know if you have the crummy intake manifold/gasket setup or the revised one? I was losing coolant and overheating when mine screwed up. I don't remember what years were affected, but there's a dorman intake manifold that can fit on the earlier ones (my GM is an 03 for what it's worth).

Already had to replace the intake last April, snapped off the heater supply nipple while bypassing that. Supposedly the big issues were fixed by 07 but in any case I've got a Dorman on there now. Coolant didn't look low during the brief look when it was showing hot.

Update on the cooling situation: sat in a parking lot to try and replicate. Starting from warm-ish with the a/c on, temperature got up to 98C. At this point I got out, poked the fan, it spun up for a second then stopped, then right as the temp ticked over to 100 it kicked on full blast. Turned a/c off, after a bit the temp started climbing; turning the a/c on at this point did nothing, nor did prodding. Got on the road for airflow again, temp got up to almost 120 before falling, stayed a little above normal all the way to parking. At some point during the drive my cap vented.

At this point I busted out the multimeter. Unplugged the fan, no continuity, but ~10V across the module terminals. Unplugged the module and probed the harness side, continuity to ground and ~12V on both the power and signal pins (this was all with key on, engine off). Plugged the module back in, probed the fan again and now there was continuity; plugged the fan back in, started the car and it was blowing full blast, a/c off.

I'm pretty sure I was making contact with the fan terminals the first time; do these have some sort of thermal cutoff in them? Could I have had a loose connection and now it's reseated? Who knows! I'll keep an eye on it for now.

I spray and pray but with deoxit not bullets.

In my 08 I've occasionally got weird errors due to corrosion in random connectors. The first six months were rife with random light codes, like "PASSENGER SIDE AIRBAG SQUIB FAILURE" then having to track every underseat or dashboard connector and cleaning them.

Just two weeks ago my wipers/fluid stopped working (again). Started working the moment I started to pop off the wiper motor cover (accessible without removal). The cover houses the control board but there's a pogo pin style connector inside, moving the cover scratched it a bit to start working again.

Last year when the wipers stopped initially due to flooding the motor during a rainstorm (drain was clogged with .40S&W casings and dirt) I opened the motor up and reflowed the board, but never got intimate with the connector itself.

Alright it seems like the fan blows nice and strong when the car first turns on, then gradually gets weaker, then eventually stops blowing completely. In my experience digital modules do not fail this way, so I've gotta be looking at a fan that's somehow marginal and dies as it heats up, right? I've already replaced the module, no change in behavior.

I loving hate shotgunning parts but my google fu is coming up weak, can't find a loving circuit diagram, or even "range of coolant temps where the fan should be on". The ECU is reporting temps just fine, but is there a chance the fan runs off a different sensor that could be hosed?

Editing to update:

Fender Anarchist posted:

Edit: I loving GOT IT. Checked on the laptop to verify the signal was getting to the fan, went out and saw the fan was off, gave it a strong flick with my flashlight.... and it spun up. With a horrific grinding noise coming from the hub. It is dead quiet when it's cold and blowing full blast. Must be something rubbing/gripping when it gets hot, that's strong enough to fully stop it at low duty cycle, and stall it even at full power once it's stopped. gently caress that feels good to finally figure out. Guess I'm getting a new fan assembly.

Out here, everything hurts.




I love chasing wiring issues. Mine is currently that my odometer backlight works fine when it's cold outside, but as soon as the car heats up it fades out to unreadability, and if it's hot out it stays that way. Probably a lovely connection somewhere, but I'm not going digging under the dash until spring for something that doesn't effect driving.

Already ordered a replacement off Amazon for $120. The only LKQ that shows one in stock was over on like the gulf coast. Frankly the time saved with Amazon vs junkyard hopping while actively nursing a car to keep it from overheating is worth the extra $40 vs junkyard price.

As long as it’s as good as OEM, yeah.
Here, I wouldn’t even bother to look it up. Most yards aren’t online, and the Panther is so common that almost any yard is guaranteed to have one if not many. And there are two “junkyard rows” within easy distance of me, not to mention several Pick And Pulls (which I actually don’t like since they computerized and nickel and dime you for everything.) My favorite yard has a dozen Panther cars at any given time.

Well, it turns out that the PATS system was thinking that I was trying to steal the car, and it had disabled the fuel pump.
I read that a '98-'02 police ECU could be swapped in, just plug and play, so I grabbed one from the junkyard. Threw it in and the car fired right up and runs smoothly. The check engine light is on and I still can't read any codes so it may just be my scanner. I'm happy regardless.

Any known issues with slow filling/gas backups on trying to fill up a towncar? This is on a nearly mint condition 2011-L

I moved to Texas from California so those vapor extracting CARB gas pumps are long gone.

Most of the gas pumps in my area seem to pump fuel too fast for my car at full pump speeds. I can adjust the angle and it sometimes work but filling the car up is a bit of a chore depending on gas station. I'm suspecting something with the gas tank venting system seeing there's a hose/valve kit that runs into the nozzle neck to the 12 o'clock position. Not sure how to really check/test this.

I want to embrace the sub-$2.00/gallon gas prices and have full speed fillups :(

I posted here a few weeks ago about needing to redo the rear end on my Marauder and figured I'd post an update. The spider gears in the differential were toast and I picked up a 31 spline carrier for about as much as new gears and clutches would have cost (stock axles on the 2003 Marauders are 28 spline). Since I was replacing everything else in the rear end anyhow, I decided to put 4.10 gears in it. From everything I read on the Marauder forums, 4.10s were a major upgrade. I saw somewhere that Mercury had originally designed the car with 4.10 gears but had switched to 3.55s near the end of development to meet CAFE standards, though I don't know how true that is. I got the rear end back into the car on Sunday and was honestly a little disappointed. The car wasn't responding as well as I had hoped, though I figured it was probably going to be acting a little strange until I got it tuned (shift points were weird)

Got the tune today and HOLY HELL. The car is a completely different animal. Granted, it's cold and damp today and I have Nittos on the back, but the rear end breaks loose at even half throttle. It accelerates MUCH better and shifts so much smoother and quicker now.

I got the tune from Marty at Mo's Speed Shop and although I've only driven the car around for about an hour today, I can't recommend it enough. I'm not sure if they tune other Panther platform cars, but he's highly recommended in the Marauder community and I can definitely see why. If you're thinking about getting your car tuned I would definitely reach out to him.
