Have a 2017 F type base. Coolant was getting low so took to dealer who replaced a cracked pipe I think. Spent over 3k but was happy to get it fixed. But Couple of days ago after a good run, parked it and found fumes from engine bay. Noticed coolant on the frame and on the floor. No check lights and the engine runs when I got back from work. Did not dare to drive it. Considering towing to dealer. Initial talk with dealership the service person said it’s common with pressurized system for other places to show up if bad after fixing one. It sounded like a problem loop but I kind of understand it. Would think with such high labor charges to open everything up to get there it makes sense to change anything that remotely looks worn out. Wanted more info to get a better fix this time. Please help. Thank you

 

Looks to me like the classic split seam in the older style top cross-over coolant pipe.
Have a gentle poke and prod of that seam to check.

 

See this thread on the Aluminum pipe replacement for the plastic ones. I had the aluminum pipes installed by an independent shop. Works well so far and good piece of mind.

3000 $ for what work on the cat? have you any information for each step what was change?

 

Isn’t it standard procedure to do a coolant system pressure test after any replacement of parts or do you have to ask for that?

 

it was a Y pipe before. I just looked back. Finally towed it to dealership. They are gonna do pressure test and let me know.

 

I know. It was a Y pipe change and 3300. Will have to see what it is this time. Whatever it is I wish a longer solution than 3 months.

 

thank you. Will look into these. The labor to change these pipes is just crazy.

 

Not sure what all the parts/pipes were that the dealer changed for you, but here are the ones that my dealer changed (under warranty, fortunately) about a year ago. The OE pipes are 'flanged" so it is easy to visually check (for the most part) if they were changed. The replacement JLR pipes are solid, but still plastic. The SuperCharger has to come out for ALL the affected pipes to be replaced, and THAT is a major labor/time-eater. They also put in a new water pump and the AJ814053 crossover pipe. All the rest of the part numbers are here, so you can cross-check what was done on your car.

 

The dealer quoted my around $2500 to change out the pipes. I brought it to a great indepemdant shop who did it for around $1000 remove/replace + $300 for gaskets and coolant.
