in answer to your question the timing belt should be changed every 55/60 thousand miles
According to my dealer, it should be changed at 150,000 km.
Timing chains never need to be changed, only belts.
If the engine has a timing belt, it should be changed around the 150K mark. If there is a timing chain, it does not have to be changed unless it is damaged.
Every 100,000 miles.
I believe that is at 105,000 miles
it should be changed every 100,000 miles
every 60 000 miles
Should last the life of the engine and is normally changed during an overhaul.
Every 80K miles, 100K max.
If You use regular oil very 3,000 miles with synthetic every 6,000 miles
It should be changed every 60,000 miles on all years 1988-94 with a timing belt. It is not an interference engine.
