Had coolant plastic cross over pipe on top front of engine replaced because it was leaking. Dealer put on new Jaguar part. One month and 500 miles later, the new part is now leaking coolant. Dealer is going to replace it again with a 2nd new part. What could be going on here? Something like this should not happen. Anyone else have this problem? What could be the root cause? Thanks, Tom

 

So where is it leaking ? partway along the pipe or where it secures at each end ?

 

I don't know. Car is being serviced at Mercedes Dealer in Sarasota, FL. I go there because I bought it used at the Mercedes Dealer 2 months ago and have an AutoNation Warranty. I'm taking it in on Monday and will ask Service Mgr. where is it leaking. Thanks, Tom

 

Why not replace it with a rubber hose ?

 

The Dealer says the leak is in the Lower Coolant Pipe. They will replace it and add new coolant. The previous leak was the Upper Coolant Pipe. Problem solved.
