XKR replacement engine number?
#1
![Default](/forum/images/icons/icon1.gif)
Does anyone have any thoughts on the engine number found on the block near the steering rack of my 1998 XKR?
There are no marks near the thermostat housing.
Details are:- FKBHD*4444* *11222211*FEDDB
Obviously this doesn't tally with the original number in the registration document of EC9809090701
I was going to change the coolant which is currently pink and came across the link regarding changes to the spec of antifreeze around this period.
Many thanks,
David

FWIW, I believe this spec book describes the location of the engine number as well. I agree with you that it is the engine that counts, but even if you know the engine number, I am not sure Jaguar published a list of VIN by engine number to figure this out. Some folks have reached out to Jaguar Heritage and have had some success for these types of inquiries.
Other option would be to look up the CarFax or MOT history and reach out to the local dealer service department in the off chance this was a factory replacement (nikasil?).
Option of last resort is to figure out what is there and use the same.

Jaguar have consistently used the same method of V8 engine numbering based on the date and time off the production line. The original number in your registration document of 9809090701 decodes YYMMDDHHMM as 1998 / September / 9th / 07:01.
A variation was the rebuilt Nikasil engines which were rebuilt by external contractors and in addition to the original engine number also had a tag fitted with another Part Number and Serial Number.
The FKBHD*4444* *11222211*FEDDB could be casting numbers.

AFAIK the markings on the block are related to crank journal sizes, etc. I did read how to decode them but I can't remember where, I'm afraid.
The green tag mentioned by RJ is in the same place for the European market (at least, it is on mine), and can fall off (Jaguar glue).
The engine number will be there by the tstat tower, but can be really difficult to see. It's engraved there although I guess by the end of the week the engraver wasn't pressing so hard.
The dealerships should have access to the original build sheet which will carry the engine # but the information is getting sketchy these days.
I've read anecdotal reports that the newer coolant doesn't play well with the head gasket material used on the earlier cars?

Having moved to Portugal I have to have my car tested by the authorities here. This is seemingly quite a complex and detailed test including, for example, a check that I have right hand dip lights fitted. It has been stressed to me that the engineers who test the car must have a clear view of the engine number (not the VIN!) and the test will be forfeit if they don't see it. From the posts above in this thread it appears that they should see the number easily if they look at the underside of the engine. Am I right in this belief, and are there any alternative places that the number may be seen? It is not a replacement engine. Thanks!!

I still haven't found my number but as others have said it will be by the thermostat tower. On my 1998 XKR it does appear to be hidden below a couple of hoses going into the thermostat tower,
From a different thread this detail posted by GGG shows the location.

On your 2005, the 10 digit engine number is stamped on a raised pad on the front of the engine block near the thermostat housing. Not to be confused with the 8 digit piston grade reference which is also shown.
