Our 2002 Lincoln Town Car started to overheat on me the other day and I found out I had a pretty substantial coolant leak. After checking all the normal stuf…

isidro guevara says:

i had the same problem but my leak was where the thermostat is that on the bottom of it where it lays on top of the intake

RamblinAround says:

It’s been 18 days now and so far, it’s holding up great. Thanks for watching!

Nice fix.

fastdrive55 says:

I am not a salesman for J.B.Weld :-), but I can see the stuff is tougher than one may think. I have once repaired a damaged thread with is – good to this day.

John Horan says:

Great Fix, Common for the breed. I have a 98 Lincoln Town Car and I love it. I had the intake issue which I resolved by replacing the intake with the upgraded unit. I also changed out the rear air suspension with a Moog retrofit shocks and coil springs kit.

Have a 97 Grand Marquis where the manifold cracked in two places.I thought My troubles were almost over with the replacement.Guess not. Has 97,000 Miles.Thanks.

i remember the first time i saw one of those plastic intakes, it was on a mustang long long ago.. it blew my mind they could actually be that cheap, even if composite does work, its just cheap looking and has no panache. glad ya got er fixed though. quick steal to the rescue!

Bevoin1970 says:

Nice one, and I like your style, great way to fix a leak, and if it works why not. Lets just hope it holds out for the foreseeable future.. 🙂

The Shade Tree Fix-it Man says:

Good fix and great information. Should save someone some money down the road for sure.

dirtbike5100 says:

Great fix! Hope it holds up

RamblinAround says:

Thanks for watching Jim. So far, it’s holding up well.

RamblinAround says:

If I have trouble with it again, I may replace it with rubber hose too. 

Jim Bales says:

Very cool fix. No pun intended. Keep us posted. Thumbs up!!

maloarfe says:

Good to know, thanks.

wtbm123 says:

May have cam phasers going bad. I think those engines had them too.

wtbm123 says:

Common on those motors. I have seen the metal line get replaced with a rubber one without removing the intake. Keep an eye on it may leak after time because of the heat cycles. 

RamblinAround says:

Yeah, it’s my understanding that they can still break, even with the improved intake.

outdoorsman310 says:

all the new cars ive seen just want to make cheap shit to increase profit

outdoorsman310 says:

i did the intake on an explorer or something at work. it already had the metal piece

James Eggerth says:

The JB weld should hold nice fix.

knikula says:

plastic intakes…pretty sad that American cars resort to this stuff….and I’m a injection molding technician…and how much would it cost to make that tube stainless? The bad part of that repaired tube is somewhere else it’s likely to fail soon….Some car maker should brag that they don’t use plastic for critical parts…

My freind had a F150 4.6L Triton he was going to work up northern manitoba and a spark plug blew out of the head.modular engines wiki has these 2 problems listed near the bottom just warning you in case you didnt know!!!

Arbiter11100 says:

I think they use it because its cheap, and lighter.

Eric Poirier says:

Gotta love it when you catch a little thing just before replacing the big thing ha-ha. Nice job on the repair, will probably last a good long time too, that stuff sticks pretty good.

creamofcardstv says:

Thank you for sharing that! It’s always worth filming problems like that to help others in a similar situation, and as a memory jog. My YouTube videos are like an extension of my memory 🙂

mbyr31 says:

Those composite intakes are a pain. Still have to be careful with the metal on plastic, but its not as bad with aluminum.
I’ve replaced a few of these in the past. Its not really a difficult job, just looks more daunting than anything.
Great vid bud!

CountrySideClub says:

Great repair for cheap! That intake looks like it cost some big money and you saved! CJ

Ron Reason says:

Good video. Ill be getting my grandpa’s 1992 Lincoln mark vii. I like your videos, educational and fun. Can’t wait to see the next video on the trans am.

mercedes560sel says:

my 2000 Lincoln Continental 4.6L 32v is all aluminum intake, no plastic at all. It is FWD.

thechevyscrounger says:

nice ta have the ability to think out side the box ,aint it?

Deadbydawn71 says:

My brother has a 2004 and it makes a knocking sound coming from the passenger side head. He took it to two mechanics and they replaced several parts but the car still makes the noise. He drives the car everywhere and it drives fine but the noise is horrible. I know it cant be the oil pump. Any idea what it could be?

FatGuyWithAKatana says:

OH STEEL TUBES, those broke my heart once too, i ran outta gas when i had my z28 and had to replace the fuel filter, i started to undo it and watched the tube twist, replaced with rubber.

FatGuyWithAKatana says:

cooling problems have caused me lots of tears, but it was always an easier fix than this. every car with plastic intakes should have an aluminum intake available as an option.

hunkatiel says:

Plastic intakes, sheesh. Sounds dubious but I guess it saves them money. I have a 89 Thunderbird in my garage with a blown headgasket. The prototypes were blowing headgaskets on the test track, Ford knew about it but never fixed the problem. I didn’t find out about it until I joined a t-bird club and that was the first question they asked me, blown your headgasket yet? Hate it when they cheap out.

Goober Songuns says:

I had the same happen to me on a POS Cougar w/ Ford 4.6
I cut out the bad spot with a hacksaw blade & used a piece of fuel injection rubber hose with double clamps on both ends & worked until i sold it a couple years later & as far as i know its still holing up ?
Im just saying sometimes there is 2 ways to slay a snake ?

RamblinAround says:

I checked to make sure the Lincoln had the improved intake when I bought it, so I thought it would be good to go. But then, I was reading online about how some still develop leaks occasionally, although it’s a lot less likely. I’m glad it turned out to be that tube instead.

RamblinAround says:

I did the best that I could with the prep work, so I’m hoping it’ll hold for a good while. Thanks for taking a look my friend!

RamblinAround says:

Our Mercury Cougar went over 150,xxx miles before it finally cracked. I’m sure it depends on a variety of factors.

RamblinAround says:

The cost of the intakes has come down a bit…this one was about $230…and that includes the thermostats, o-rings, etc.

churchofnatasa says:

Ra,that is such a nice car,just replace the part,you do not want to blow that motor,what could be a 200 dollar fix could turn into a 5000 dollar fix,just think the milage you do

papachuck63 says:

Your repair will out last the car. I had to replace a oil pan gasket on my Cougar that had a 5.0 HO in it. I thought sense I had it off that I would replace the oil pump with a high volume pump. Long story short, it rubbed a hole through the oil pan with in a few months . I drove it five more years with it’s JB Weld patch. Never leaked again.

monarch1957 says:

I have a 93 Lincoln with the 4.6 engine but have had no problems so far with leakage.
