So while doing errands today Suddenly I See white plume of smoke coming from under the hood I immediately pull over open the hood coolant all over. Nipple from the expansion tank just broke off. What kind of s*** quality is this? Anyone have a similar issue is there an easy way to fix it?

 

From my rebuild thread. I had the exact same problem. The tank isn't hatefully expensive but this will get you on the road.


OK, good news time. Powered the car up and damn near everything works. I did need to some up with 'something' for the broken fitting for the burp line to the expansion tank. After struggling to find something that would work and have some strength to turn on the lathe and insert in the broken fitting stub I ran out of good ideas and resorted to buggery as I think our British members would say. I had some 1/8" NPT fittings in the plumbing drawer and yes, if you push hard enough, the 1/8" NPT coupling will thread the stub of the plastic fitting.




Yes, it does rub pretty hard on the brace and I'm not terribly happy about it but it hold pressure and should work until I find a replacement tank. I could have painted it black but I think the brass shows a little redneck and not terrible for what it is.


Fired it up, No leaks and the fan runs normally. Took 1.25 gallons of antifreeze and 3/4 gallon of water to top it off as it ran. I filled it through the blower port (17mm Allen). Engine is hunting so I know the puter's not happy. Some codes eventually popped up but I didn't take the time to read them. Most likely still the front drivers o2 and no change between the front and back. I will say that the exhaust note is flat out nasty with gutted cats and both resonators in play.

Overall I'm really, really happy to have made this much progress. Now to order the cats, o2 sensor and get this thing back on it's feet.

to get tank out does the brace need to come off?

 

so same unit but different part number and cheaper?

 

Sorry, part is for 2012. On this model at least the brace has to come off for expansion tank removal

 

No my friend, you never want to say that, ever, even if you actually resorted to it. Tell no one.

BTW it was illegal until recently.

Some Brit has played a cruel joke on you. However, best line I have read on this site. When all else fails resort to a bit of....

Jag could use that for their slogan- "what have you had resort to keep your car running?"

God I can stop laughing.

 

...should we let him in on what it means? Have to say, funniest post I've read all day...

 

Wait till the Brits wake up and read it.
I can just see the spilled tea and coffee.

Mind you, George Michael did the same for even more trivial reasons.

 

I'm at a loss to its meaning. Color me intrigued.

Edit, thank you WB for the answer. I am no longer intrigued and regret my choice of words.

 

Well, the part breaking was kind of a pain in the a$$...

 

Oh, I know what it means. Part of the fun of being on an international forum is using locally uncommon phrases. The buggery part is using one part to fit the other to it though in a mechanical and not sexual manner and having the 'outie' fit the 'innie', not vice versus.

Glad I could make you smile.

 

I thought you had found a good way to clear your head.

 

All jokes a side I'm worried , I took the rest of the nipple out of the hose and it's very brittle, turning into mush as I poked at it with a screwdriver. I than examined the bleed cap and tried scratching it with a screwdriver, same results turns easily into mush, what the...isnt plastic made for cooling system suppose to be coolant resistant?. Makes me wonder what else can fail in the cooling system soon, and if there is anything major that can break.

 

It's just the fiberglass reinforced plastic (FRP) breaking down. That nipple is for the burp line so any air or steam flows through it and the steam causes the plastic to break down. Plastic T-stats do it as well as the molded plastic hose joints. On the Lincoln LS, it's recommended to replace the entire cooling system after several years of running or one overheat situation.

 

Good morning,
I spent a few years working as a tech engineer in the plastics industry, a few with nylon.
Cooling system parts are made from Type 66 Nylon, typically with 30 - 40% short glass fibres, unless translucent. It has a "stabiliser" added to the mix to minimise the effects of exposure to hot water, hydrolysis, which breaks down the structure.
BUT, even with that, the stuff has a sudden drop off in properties at around 10yrs;showing up as parts going brittle and weak.
Antifreeze makes it worse, and then they found that the long life stuff is even more destructive..
So, no matter what make/vehicle, if it is regularly used and has nylon rad tanks etc. this can be expected..
The auto industry just loves the stuff though, $$$ and easy to make weird shapes..
Wasn't copper wonderful??
I can buy an aftermarket aluminium tank for my RX8, same problems..
Just one of multiple reasons why modern cars are unlikely to be popular as resto projects.
Now I will find that brass fitting to have handy for our 07..
Regards

 

Yep Alex, they do deteriorate with time and heat. Just a part of our lives now but you got 9 years out of the part (just another way to look at it.) And there is nothing unique to Jaguar in this instance (except the replacement part price)

 

I have something to share about the QUALITY comment that was made.
This tank is 10years old. It was probably made in 2007.

I think its FANTASTIC quality.
You would not believe that in my Chevy truck I have had to replace the plastic intake gasket 2 times in the same length of time. Yes the entire top of the engine has to be dismantled.

The difference is that when something like this happens to a working man's car, he just fixes it and doesnt say why is this happening to me. So you dont hear of all the plastic that fails everywhere.

 

I finally had to replace my power steering belt on my '68 Fairlane last year. It still had FoMoCo embossed on the outside so I suspect it's original and only 50 years old.
Car has 34k miles.
