Ford Aerostar :: 1990 - Heads Leaking Front And Back Freeze Plugs?
Oct 25, 2007
M y 90 aero 3.0 heads are leaking front and back freeze plugs. I think back ones are pretty accessible from inside. How hard to change it . I changed block plugs. What size are head plugs?.

Mine has a 4.0 V6, the freeze plugs are leaking coolant, the guy at the shop said it will require pulling the engine to replace them. Is there an easy ( less expensive ) fix ? I was told I could use block sealer, is that an option? She has appox.160,000 miles...

So I am working on my 5.4 I pulled and discovered that is is very oily behind the freeze plugs. The motor is on a stand and has been upside down a few times. There was still a little oil in it as I can see a decent puddle under it where I didn't tighten the drain plug entirely. Why would there be oil built up there? I have the two from the back of the heads out and the two on either side closest to the rear of the block. What kind of issue am I looking at? Here is the build thread that I am doing about the truck and this motor.
DH-Rear of Driver Head
PH-Rear of Passenger Head
PRBS-Passenger Rear Block Side
PMBS-Passenger Middle Block Side
DRBS-Driver Rear Block Side
DMBS-Driver Middle Block Side

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?

Just hit 70,000 miles and went out of warranty. The issue is the Heads Up Display periodically shows "Check Back Up Sensor". When this occurs the sensors do not detect, and this doesn't happen all the time. I did clean the lens on each of them.

So I am on my way home after an honest 8, and I make it a mile down the road and goose the old girl a little off a stop light. Well next thing I know we have smoke rolling out under the hood, well it turns out the "smoke" was r134 refrigerant. The guy that recharged it said that the compressor failed and that its common with retrofits because 134a runs at a higher pressure.
Now I don't need a/c, and I might just leave it as is, but it would be nice to have the old girl working 100%. It also turns out that the front seal of the transmission is leaking, I am debating whether or not to just have the transmission rebuilt. it shifts fine but its gotta come out anyway. Its a 700r4 and the trans guy recommends stronger 3-4 clutches and a shift kit to make the holding pressure higher.

I want to replace the lock cylinder which apparently I should have already done but now the key won't turn at all and the wheel is locked in place, so I can't turn the key to the run position in order to remove it. Is there some way of working around that?

My fuel pressure is at 24 engine of and 29 engine running. Is this a bad fuel pump? I was told that it is supposed to be between 40-45 PSI. Is this correct?

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.

I have had an intermittent Check Engine Light for a couple of days --- the van started and ran fine, but the CEL would come on after about 15 minutes of driving. It would sometimes go off before I reached my destination, but it was always off the next time I started the van. No sweat.
I went to read the codes this afternoon and now have a problem. I put one end of a jumper wire into the Self Test Input (STI) and then accidentally let the other end of the wire touch the 12V connector of the starter relay (why is that thing unprotected anyway?). I saw a little arc so I know there was some current flowing.
After this, I connected the STI to SIG RTN for reading the Key On Engine Off codes and got no pulses at all. I rechecked the jumper wire but got the same result. I then removed the jumper and started the van --- it ran quite rough and would only stay running by giving it plenty of gas. The CEL was on the whole time. I did this a couple of times just to be sure.
I guess there's nothing more annoying than turning a little problem into a big one... crap.
I couldn't find an electrical circuit diagram showing the STI in my Haynes manual, so I'm not sure what is likely to have been damaged. I assume the engine control module (ECU) has been damaged, but that is just a guess.
Some specific questions:
- where is the ECU?
- Should I spring for a new one (depending on the ID number), or is one from a junk yard just as good?

I have a 94 Camry left to me by my father inlaw when he died a year ago. I notice antifreeze coming from a weep hole just above one of the alternator mounting brackets. Whats involved with replacing the water pump and timing belt? Im guessing thats what it is and while I am in there I will replace the timing belt as I dont believe either have been replaced. The car has about 160,000 miles on it. I kept my Windstar going for about 250,000 miles before my daughter wrapped it around a tree so Im sure its something I can handle. The problem is time as we are getting into winter. Is it a major job or something that can be done in a few hours?

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?

Ok my 2000 Toyota Celica GTS is having 2 very bad issues.
1st - It is hesitating very bad when doing "cold starts" and nearly dies when I turn the A/C on (engine code reads : Random/Multiple Misfires on all 4 cylinders)
2nd - I have to put in 1 pint of Anti Freeze every single WEEK! It is not leaking on the ground as far as i can tell too.

I have a 1990 Aerostar 4WD, 4L, with about 120k miles. About 6 months ago I started my van and noticed under it that gas was dripping onto the exhaust at the Y-joint and evaporating. I shut off the van and drove another car to work. That evening with fire extinguisher at hand I drove my car up on ramps and quickly got under it looking for the leak. NOTHING. 6 months later...yesterday. I drove for a few blocks from home and notice heavy gas fumes etc. Stopped the van and again gas was dripping onto the Y-pipe joint.
This was an explosive situation... I pulled off the doghouse cover and saw, smelled and touched gas friom on the right top of the engine near the back. My questions are: What could randomly be leaking at this location and is it fixable without pulling the engine. I pushed the van to a secure location and am afraid to turn it on. Maybe I will drain the gas tank before then. I am just now trying to find the schematics for the fuel line delivery stuff. Where to go for a manual.

Ok all.. been working on the 88 getting it running (3.0L EB 2wd). It does run now pretty well.. definitely need some suspension work.. but that's a different post. I have had the rear main seal replaced and the oil pan gasket replaced to stop the oil leak. There is a lot less oil on the ground now.. but still leaves spots on the street. It appears oil is leaking down the oil pan from above and dripping off of it to the street. I also had the main cap bolts replaced (one was broken and the end was in the oil pan).

I replaced my MC cap and gasket less than a year ago with a Dorman replacement and I'm leaking again, already. I don't want this to be an annual thing! Any good quality replacement? Is there any tip or trick to get the gasket to seal better?

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 recently came home to a shattered back window on the lift gate. We were gone on vacation for a week and I didn't notice it for a couple days after we were back. The van was backed up to my second garage door. Not really sure how it happened. Nothing was taken from the van and I live in a pretty decent neighborhood, so I don't think it was vandals. Only thing I can contribute it too is the heat (it had gotten pretty hot in WI while we were gone).
So I'm in the process of replacing it. After a pretty good search I was able to obtain a used window from a junk yard. The glass is in good shape but it is missing 3 of the 'studs' that are imbedded in the rubber molding. I have the 3M Window Weld butyl 'tape' (3/8") to seal/adhere it to the fiberglass. Will the remaining studs plus the tape be enough to permanently keep the window in place?
If not, I can salvage the studs from the old molding but then I have to figure out how to glue it to the new window. I'm not sure what I can use to do this. I've considered JB Weld, Epoxy, super glue or something like rubber cement. It looks like the old studs were ripped straight out leaving kind of a void in the hard rubber molding. The bottom of the void is I believe rubber (not glass).

Passenger side valve cover leaking. My local parts stores have two brands.
Fel-Pro and MAHLE Original.
Any comments, preferences, anecdotes? I don't want to do this job twice.
