Bought a '98 XJ8L back in January, at a good price, but considering who it was purchased from, I expected to have to do some work on it.



With some invaluable guidance from this forum, I dove in. Replaced the fuel pump, cleaned out the throttle body, changed plugs and air filter (about 30K miles overdue), replaced the coolant reservoir, airflow sensor and intake, PLUS has the transmission rebuilt. Now, another minor issue has cropped up: a leak in the cooling system.




You can see the crack where the hose connects. Question: can someone ID this part so I can try to locate one to replace it? Thanx!

 

Welcome to the forum Jim DeVault,

I've moved your question from General Tech Help to X308 forum. Members here with the same model will be able to help.

Please follow this link New Member Area - Intro a MUST - Jaguar Forums - Jaguar Enthusiasts Forum to the New Member Area - Intro a MUST forum and post some info about yourself and your vehicle for all members to see. In return you'll get a proper welcome and some useful advice about posting to the forum.

If I am understanding which part you are indicating is cracked, it looks to me like what they call the "water outlet pipe". Part number NCA2241BC

(part numbers AJ85885 AJ82216 NCA2241BB and NCA2241BC have all been ascribed to this part, but when I search any of them they bring up the same item).

 

That's the outlet pipe or crossover pipe AJ85885 available online from many suppliers. This is a good time to replace the thermostat housing with aluminum, also thermostat and hoses.

But more important, are the secondary chain tensioners upgraded to the metal body 3rd gen?

 

That seems to be it. Thanks!

 

That's a very good question, to which I have no idea of the answer. How would I tell? My guess is that, considering that the previous owner didn't even bother to gap the plugs when they were changed, I doubt it.

 

Pull the cam covers and take a look!


If it has the orange/brown plastic tensioners, leave it in bits until you have installed the metal ones.


If it has the metal tensioners, button her back up and enjoy the car.


It is too much of a ticking bomb not to check, there are too many threads on the forum about tensioners letting go and wrecking the engine!

 

Do not start again until you check the secondary tensioners. You have been warned.

 

Jim,

....... and you only came along with a simple question about a cracked piece of plastic!

All good advice about checking the tensioners. Several forum members with various V8 Jaguar models have had reason to regret not finding out type and condition until it was too late.

The good news is you seem able to do the work yourself. There are many, many threads on replacing the secondary tensioners. Expensive at the dealer, less so at an independent, under $200 if you do the work yourself. Just read every bit and have it memorized.

Same deal if you decide to change the plastic Thermostat tower while replacing the crossover pipe. For a few bucks more and another twenty minutes you could change the water pump as well. Do not lean on those plastic pipes running from the overflow bottle.

 

I have a pragmatic approach to auto repair, and simply stated, if I can reach it, I can probably fix it. I just took a look at an article (not on this forum) that went into great detail, and it looks like a pretty hairy job.

I'll look into it, and if the added cost is worth not having to undertake it myself, I'll go that route, but one way or another, it will be money well spent. Already hearing a little tick from the front.

Thanx all!

 

You can definitely do the secondary tensioners your self with the zip tie method. There is a good procedure in the DIY sticky.

 

As for the water outflow pipe, be careful where you buy it. I purchased mine from eBay (due to the sensor in the middle literally shooting off and spraying hot coolant in my face). I paid about $80 after shipping, they can be had for around $50. Try RockAuto or CarID.
