I have a 1990 xj40 4.0 sovereign with 104k miles to which I need to
carry out a few maintainance issues over the weekend. Before I do
this I just want to be clear in my head of a few questions and as
always your help is appreciated.
I checked my Distributor cap this morning and each of the
contacts is white and pitted. The brass contacts on the rotar had
lost it’s brightness but cleaned up with a green kitchen scourer
leaving me I guess just needing a new cap. I may as well change the
leads at the same time. Are the leads and cap unique to Jaguar and
must be got from a dealers or can they be purchased from Halfords
or the like. The spark plug cap end of the leads looks special to
the engine to seal the plug opening.
I have finally found my slight coolant leak, I kept hearing
Bryan say that it can only lose water from a leak or the
headgasket. Thankfully fearing that I have found that after turning
off the engine a slight trickle comes from the lower bolt securing
the waterpump to the engine. Does this mean a gasket and waterpump
removal or can the bolts work loose and just need to be tightened.
I keep intending to replace my transmission fluid, but kept
putting it off whilst I pondered whether to replace/clean/leave
alone my gearbox filter. I did post a discussion on this topic a
while back regarding this and got many mixed replies. some say
renew only with OEM (�30), others say it is course and can be
cleaned, others say leave alone for the mess it is not worth the
little benefit. I also seem to recall one lister saying that Jaguar
themselves do not renew them now so I telephoned the local dealer
that I use and spoke to the service manager who told me that on the
newer ZF 4 HP 24 E9 electronic transmission they still recommend
renewing the filter and do so themselves. He said it was an easy
job, 5 bolts to remove the sump and then a 20something torx bolt to
remove the filter. What is this Torx thingy I have to buy, and what
size do I need? I don’t need a new sump gasket I have been told as
they are rubber and are reusable? don’t want to be half way through
and find I can’t finish.
Thanks as ever–
