Joe, I assume it is. My understanding is that the oil cooler thermostat is bolted to the water pump and that is the one I need to change. Do you know if the Jaguar part number quoted as JD61162 is for the updated assembly? Regards Richard

The 2004 X-Type 2.0D that I have owned for 10 years is running cool and I have been led to understand it is probably the Oil Cooler Thermostat that needs changing. On a long run, the engine thermostat seems to be opening and closing correctly - it is just that the engine is taking much longer to warm up and the temperature gauge is definitely not coming up to it's normal reading - about 1/4 instead of just under halfway. The problem is, I cannot seem to find the correct part number. Having trawled the net, it appears that Jaguar introduced a modified unit to heat up the engine quicker and that it may be a different one to that used on the similar 2.0D Mondeo. Does anyone have any definitive information on the part number(s) I should look for please?

Rowley, Put it down to age! Dave is the kind chap who sent the original post. I have looked on line again and seen a guy selling a dipstick for a 2002 - 2005 diesel Jag. He doesn't state 2.0 or 2.5 but my VIN number is within the ones he states and the part number is one of those stamped on my dipstick so everything fine and dandy. Thanks to you and Dave for your help.

Thanks Dave, It looks like my Transit dipstick is the same size - 564mm (22.2") to Full and 583mm (2.95") to Fill. Interestingly though, even though your car is the same year and model as mine, it has a red dipstick like my Transit one but my original one was yellow. I don't suppose there is a chance yours has been swapped out in the past as well?

Dave, That is very kind of you. I'll measure mine later and let you know the result. Richard.

I have now had my 2004 X Type 2,0D SE for 10 years and if I say it myself, it is still in pristine condition. Some years ago, a local garage lost my dipstick whilst changing the oil - although of course they denied it. Instead, they supplied me with a Transit version which my local Jaguar dealer, said was the same size. However, many oil changes later, my current independent has told me that he is absolutely sure he has put in the correct amount of new oil after thoroughly flushing out the old and the level has come well above the Max mark on the dipstick. Would any other 2.0D owners be so kind as to measure their dipsticks from the base of the handle to both the min and max marks so I can confirm if indeed both dipsticks are the same dimensions. Thank you in anticipation of your help.
