Afternoon folks, as i go through the preventative maintence jobs on my car its thrown up a problem. Both are x100 versions , one a 4.0 1999 the other a 4.2 2003. Both supercharged. Can you tell me where i can readily find part numbers for these engines. I look on jaguar classic parts but it is a bit vague regarding the xkr. Anyone know off hand if the water pumps, thermostats and belts are the same on both cars?. Thanks for any assistance in advance.

 

Same water pump same thermostat
I'm using US MOTOR WORKS US4124 pump 2 years no problems I paid 30$ iirc works fine
I would buy OEM thermostat or mahle , I tried motorad beck arnley they stuck close suddenly within 2 year

 

Great thanks. Would you know if the belts are also the same?

 

4.2 engine require different belt bando or Conti works great
