I have a coolant leak , it's coming from a plastic tee that has a small crack in it, its near the water pump... what's the name of the tee or if possible a part # because I can't find anything related to it... please help. Thank you

 

If it's the T shaped pipe that connects two hoses in the center of the car, my guess is that it's the upper radiator hose. I had the exact same issue (if I'm understanding what you've written) and I'm having to replace the upper radiator hose. It's consists of the T shaped hard plastic like pipe that drops down and connects to the thermostat, and two hoses extending from the top of the T on each side. I purchased a new one from this site for $91, $106 with shipping. That was the best price: 2003 JAGUAR X-TYPE Parts - Direct JPLV Porsche Parts.com

If I'm understanding you it would be the part to the right of the number 9 in the diagram from the link above. Hope this helps.

 

Can you replace the gasket on that only or is that whole part needing to be replaced. I currently have a small drip from that gasket block.

 

Part 9 is the correct part for the Upper Radiator hose assembly.

Take a look at these two post for more info.

I replaced just the gasket. Wasn't easy... but I did it.
My dealer had the part in stock. It's sort of like and O ring but has a retangular cross section. Cost about $1.50 US IIRC.

 

Alfaveloce did you run into any problems getting the old gasket off? Did you replace the thermostat as well? Just wondering because I was about to take on the project of replacing the upper radiator assembly with thermostat. Figured that if the gasket went then thermostat would be close to follow.

 

Alfa can you describe the steps you took? I have that same square rubber gasket that I h e antifreeze leak from and need to replace that part.

 

I had an advantage, in an unfortunate kind of way, because I also had a radiator leak and had to replace the radiator. So I pulled the radiator out first, and that makes a huge difference in the access.

Also making it hard to describe is that the car is in Alabama right now and I'm in Texas. It'll all come from memory. But I'll give it a try.
1. Drain the coolant. You can access it from the lower radiator hose fitting at the radiator. There is a small drain plug there.
2. Remove the upper radiator hose.
3. If I remember correctly there is another hose near the front right of the engine on that plastic tube. Probably have to pull that one also.
4. There are a couple of attachments on the plastic tube that hold it on the front of the engine. Probably hiding under the wiring harness. loosen those. You may not need to remove them.
5. You may need to remove the hose from either below the thermostat or from the oil cooler at the oil filter.
6. That leaves you with the two nuts that hold the flange that has the failed gasket in it. Those are at a tough angle with the radiator installed. But the good news is they should not be all that tight. It's a o ring like seal. So the flange is just bottomed out on the water pump (aluminum) side.

Clean it all up. May need some emery cloth on the aluminum face. Careful. Not too much. Assemble reverse of disassembly.

Hope that helps.

 

I didn't see there were two questions. Just saw the second one... I didn't do anything with the thermostat itself. I didn't have to pull that fitting apart. I was able to reuse everything except the rubber gasket, even the coolant since it was brand new.

I had just done an engine swap, and the new engine had a leak at the thermostat flange to water pump housing junction.

There is no problem getting the old gasket out if no one ever put any kind of wicked gasket glue in there. It comes right out.

 

Thanks for the info. Now I'm just going to have to come up with the time but a gasket is much cheaper than the whole assembly.
