I was wondering if anyone here could give me some good advice on the
little “or not so little” problems with my car.
The seriousness of the problems (or the cost of repairing them) is
unknown to me because I can’t appear to find a source for the problems.
The story goes like this.
I’ve had the car for about three years. When I bought it it was
something that could be called a wreck. During these years I have spent
quite a bit of time in the garage repairing, cleaning, fixing and
generally fiddling around with the car. In the summertime (3-5 months
here) I used the car as a daily driver, during that time it never
developed any new problems. Until last autumn when I replaced the vacuum
diaphragm and got the engine nicely going. Well after changing the
vacuum diaphragm and getting the car running nicely I made quite many
speeding experiments (during one I lost my drivers license ). And
suddenly problems started to pop up. I stored the car for the winter and
decided to forget all about it for a while. But now the summer is
approaching and I’d like to fix the car to be able to use it again and
feel the enjoyment of having a Jag :).
Well one of the problems was that the transmission started acting funny.
When the car is cold and I put the car in gear, nothing happens. Nothing
changes if I move the lever in any position. When the car has been
idling about 10 minutes after the working temperature reaches normal,
the car starts moving as normal. When the car moves again, and i press
the pedal to increase speed, it sometimes resembles the feeling like the
clutch would be slipping (on manual boxes). Could there be a somekind of
problem with the transmission oil movement. Perhaps the pump has
something wrong with it or something? And sometimes when heavily
accelerating the transmission starts slipping again. This problem is not
as mysterious as the one to follow (because It can be fixed with a trip
to transmission workshop) but I’d like to fix it myself and if anyone
could give me any suggestions I’d greatly appreciate them.
The other problem is with the cooling system. Before the vacuum
diaphragm replacement the car was constantly a bit overheated. I was
used to the problem and my driving style was adjusted according to it,
but after the change everything went to normal. The engine was nicely
cool even in heavy conditions. But approximately at the same time the
transmission problem showed up the cooling system started to act really
strangely. The car now overheats whenever It runs. The overheating shows
drastically up when idling. When the car is moving then the temperature
stays the lower the higher the speed is. As much as I have observed the
system I noticed that the electric fan isnt moving like it moved before
the system encountered problems. Now it only sometimes starts moving
when the gauge shows high temperatures. Sometimes the gauge shows 95-100
degrees C and the small fan doesnt do anything. Sometimes the temp reads
~85-89 and the fan does what it is supposed to do and the temperature
drops or stays where it is supposed to be. Before this problem appeared
the fan always worked for a while when I turned the car off, but now it
does that very rarely. Even then when the car is severely overheated. I
made a cooling fluids change a while ago (before I changed the
diaphragm) and one of my theories is that It got a bubble somewhere
where there shouldnt be one. I have vented the system from the screw on
top of the radiator and I have let air out under the cooling sensor on
the drivers side of the engine. Still the problem stays. I cant seem to
figure out any logical explanation to the problem so I’m turning to you
as the people who are somewhat more experienced in the field of jaguar
mechanics as I am. Maybe you could help me.
Thanks in advance.
