Tensioner Dates ?
#1
#2
The engine plant converted to metal tensioners on August 13, 2001. That converts to an engine serial number 010813xxxx (YYMMDDHHMM). There were certainly engines in the assembly process with plastic tensioners for some unknown time beyond that date. Engine serial numbers are very difficult to read in the car but are available with a polite call to the dealer with the VIN.

We have the full VIN and full Engine Number on the UK V5C (and EU) Registration Document.

Mine is sorta under the water pump but apparently there was another location based on some unidentified date of manufacturer . . . perhaps the change from AJ26 to AJ27.

My engine number is on the LH side of the block. It's not hard to see with the left front wheel off under the exhaust manifold. It starts with LL then YYMMDDHHMM. I thought the 010813 date was when they changed from Nikasil to steel liners. I had the red plastic tensioners on my 2001, but engine build was before 2001 and it's definitely Nikasil.

I copied this from a post at sometime in the past, with apologies, author forgotten:
"The first steel lined engine was numbered 0008181043 which equates to a manufacture date of the 18th of August, 2000 at 10:43am. But, don't assume that a car manufactured after that date has a steel lined engine as, Jaguar still had stock of Nikasil engines and were fitting them at the same time as steel lined ones until their stock ran out. That is why you cannot rely on VIN alone."
