Yes and in some cases you need to do the thermostat as well as a replacement stat can require removal of the belt and for the cost of the part it would be silly to ignore. Which engine do you have in your Skyline?
hi turbonutter 69,yeah took the advice and done all above mentioned,i am lucky as one of my sons is a mechanic,the car still had original cam belt which was starting to crack,even though the car has done about 40.000 miles the belt was as old as the car which is on an s plate .
