Ford Aerostar :: 1991 - Freeze Plug Leak While Driving
Sep 9, 2013
I developed a freeze plug leak while driving into town in my 1991 Aerostar with the 3.0 liter engine. Got to Schuck's (my destination) and bought some antifreeze, noted where the leak was and filled up the coolant system.
Drove a few miles to the mechanic's house. Coolant blowing out everywhere, obviously boiling off. Let it cool down while going over an estimate for repair. Topped it off one more time and went home. Have not moved it since.
There is sludge, almost like thick foam, that I suspect is what's left of coolant that has had the water mostly removed. It is the same color as the coolant - bright orange-ish green. Will a few flushes with fresh water clear this out of the system?

91 Dodge D150 1/2 ton truck with a 318 (5.2L). Approx. 135K miles. Noticed a leaking freeze plug right behind the starter. Removed the starter & replaced the offending plug. I've also replaced other plugs on the block as needed in the past. While I had the starter out, I went ahead and replaced it as it was getting old & tired. After buttoning everything up while adding coolant, I got a major waterfall coming out between the trans and the engine block.
My project for today is to remove the transmission so I can get to the rear plugs and replace. How many plugs are back there? I'm obviously changing all the plugs back there along with the rear main seal. Is there any advantage going with the brass plugs or should I just stick with the regular ones?

It would appear as though my steering leak on my 1991 Aerostar is coming from the seal, where the steering shaft enters the steering box. I'm trying the Lucas treatment but it doesn't appear to be working. Can this seal be replaced WITHOUT replacing the entire steering box?

2000 Dodge Neon having issues with freeze plugs falling out. Have replaced at least four freeze plugs over the last year and a half. Is there a solution to avoid constant replacement? Neon has about 135,000 miles. There is no warning when a plug is about to fall. Research shows freeze plug issues are not isolated to the Neon and perhaps copper plugs are the answer.

I have a '95 Chevy K1500 5.7 and am wanting to install a freeze plug block heater, but I'm having problems knocking out the existing freeze plug and would like some hints. It is located directly behind the oil filter, so I'm having problems getting enough leverage.

My engine stalls when cold or warm, when put in gear or idling in gear at a stop. If I left foot break and give a little gas I can usually keep it going. I ran 2 bottles of fuel injector cleaner through, but no dice. Could the fuel filter need to be replaced? If so, where is it located? 1991 Aerostar 3.0 Auto RWD

My truck had a small puddle of anti-freeze under it last week. It has been sitting for a couple of weeks with no issues until I noticed the puddle. After I cleaned it up, it hasn't leaked for a few days. I obviously can't find a source. What could have caused it to leak and then suddenly stop?

1991 aerostar 4.0 ... My van was running well til last week.it allegedly has 77000 miles on it. It started running really rough within a 50 mile period. I've quit driving it til I am sure. I am not harming it. I put a vacuum gauge on it. It wildly fluctuates between 3 and 7 pounds at idle. I've tried plugging the four vacuum lines one at a time to eliminate the accessories as the problem.the check engine light is off and my scan tool shows no codes.i unhooked the exhaust at the manifolds to make sure the cats aren't clogged.it doesn't have egr. There's no water in the oil or bubbles in the radiator.i have a compression tester but id like to avoid trying to get to the plugs unless necessary.

Have a 91 Aerostar that won't start. Has fuel pressure, pulse to fuel injectors, strong spark, strong compression, etc.
Thinking that the spark may be coming at the wrong time I tried a spare ignition module that I keep. No luck. Since my distributor had a lifetime warranty I got another one, again, thinking spark was coming at wrong time. Nothing. Engine won't even pop.
I am going to drop the front pipe in the unlikely even that the new converter is plugged or, somewhat more likely, the muffler, but I am leaning toward a computer at this point.. Still don't understand since it is getting spark and gas why engine won't even pop.

How to remove roof rack on 91 Aerostar? Google and search box here yielded no result so a new thread is likely in order. I have leaky roof. Not windows.

Will interior door panels from a '91 Aerostar fit a '96? No power windows or locks. The panels in our '96 are busted and I found a good set in the salvage yard in a '91. Lady at salvage yard says they're different, but I'm not so sure. Also, will the windshields swap?

I have a 1991 Aerostar 2wd 3.0. I recently had freeze plugs replaced and the mechanic had to drop the tranny to get to some. Now the shift cable has come off the gear selector lever. I have googled everywhere and can't locate the procedure for reattaching it. My mechanic was doing the work on the side and charged me only labor for his assistant. He is at work right now..

I have a 5.0L with around 144k mileage. I noticed a reasonably severe leak of anti-freeze the day after I had the oil changed at a shop (coincidentally?); nothing out of the ordinary on that day. The temp's have never showed as being beyond normal. I saw that there was a bit of weeping from the water pump, so changed that believing that the gaskets might be the real culprit (third pump on this truck). I re-filled the system with fluid (green silicate as the system had been modified several years back), ran the engine, and found that there is still a leak, not as severe, but most definitely bad. It honestly appears to be dripping at the oil pan gasket, just left of the crank on the lower end. The location doesn't really seem logical to me.

My dad and I are having allot of trouble getting our Aerostar to start up . It is getting fuel and spark , and it won't even run with starter fluid . It was running ruff before this . It is getting an all clear on the OBD codes . We took one spark plug out and it was pretty dirty , could that be our problem? Like I said we are getting spark , when we do a spark test . We are totally out of clues .

I recently changed the plugs on my 95 Aerostar 4.0L. I noticed the last service person did not replace with proper plugs. The van was missing occasionally.
The passenger side rear plug was rusty. I noticed a small loss of anti-freeze during the past year also. Could this be a lower intake gasket? Have not noticed any anti-freeze in the oil nor any exterior engine leaks.
I recently drove it for 150 miles. Sometimes after start it would miss, other times not. Looking for the type of diagnostic to be done.

I removed all the spark plug wires for testing/cleaning and install new spark plugs, but stupidly forgot to mark the wires where they came off at the Coil Pack. yes, Now I cannot find a diagram for the Driver's Side wire positions at the Coil Pack.
(The Passenger side wires are 1-2-3, starting from the front of the engine, simple enough); The Coil pack itself has numbers stamped on it, so I have the Passenger side done correctly.
But the Driver's Side wires are not in a Sequence of 4-5-6, instead they are 4-6-5 (or something like that), and I can't remember their positions at the Coil Pack. Looking for a drawing showing the Driver's side Wires as they connect to the Coil pack?
Example:
Front Driver's side plug wire connects to which coil pack position? (Front, Center, or Rear?)
Center Driver's side plug wire connects to which coil pack position? (F, C, or R?)
Rear Driver's side plug wire connects to which coil pack position? (F, C, or R?)

Well I've got an nice steady leak coming from the front of the pan.... running aft of course (downhill, windflow). She's down right now for an AC overhaul and new PS pump/hoses, but I'm inspecting to see what is next to get this stinking oil leakage stopped.
Front HB removal and seal of course, done in situ (in position). But if it is actually the oil pan/seal, can that be done there also? Front of the pan looks tight to the crossmember, and how the internals look (tray baffles, pump pickup) I've no clue if it will come off. Once she is back up and running I'll ascertain where this leak originates.
Interweb searches show the 90-94 4.0L engine is notorious for pan gasket leaks. None of the writeups I've found thus far determine if that pan can be pulled where she sits.

I have been having to add 1-2 quarts of oil every 2-3 days. I have noticed the back of the engine wet, but have seen no visible leaks unless the engine runs then it drips. Does it sound like a valve cover gasket problem or a rear main seal?

I have a 1990 Aerostar that has leaked gas 3 or 4 times. I am not sure where it is coming from exactly but it seems to be towards the back of the engine, kind of near the torque converter. This leak happened 2 days ago when i was warming the van up and it was cool outside. The time before that, it was after driving for a while. The day before yesterday I drove it probably 50 miles with no problems and it was about 85-90 degrees outside. I drove it today and there was no leak and today is a cooler day.
