Question : I AM driving a 2002 Nissan Cefiro 2L V6.
1. Do I need to change the timing chain? If
yes, what is the suitable mileage?
2. Whenever I drive through uneven roads or
potholes, I can hear a clocking sound presumably from the suspension. I have changed all four
absorbers and mountings but it is still the same.
Will the spring or drive shaft contribute to this
kind of disturbing sound if they are damaged?
3. There was a time when I drove my car up-
hill and when I stopped to a standstill due to a
traffic jam, the car moved backward even when
I was in D. Is that normal for this kind of car?
I've driven other automatic transmissions but
this was the first time I encountered this kind
4. I have been told by some mechanics that
less maintenance is involved with V6 engines
compared with in-line 6 cylinders. Is that true?
1. There is no fixed life for the timing chain and
usually when the car is in for regular service or
when there is a need to do any work on the heads,
the technicians will have a book at its condition and
make a recommendation if it appears worn.
2. Noise from the suspension area can come
from very small movements and you may want to
look at the suspension ball joints and also the upper mountings of the front struts. Also have a book
at the front wheel bearing free play. If there is too
much movement in the bearings, you will get a lot
of 'clunking' noise from the suspension.
3. Yes, the car can roll back because it depends
on the set idle speed. If the idle speed is quite low
and the slope is steep, there will be insufficient
torque in the torque convertor to hold the car.
Remember that at idling speeds, there is a lot of
slippage in an automatic transmission.
4. Not really. If one wants to speak of complications, the V6 has much more parts and should
be more expensive to maintain. However, either
engine would cost nearly the same if you maintain
