How often do you change the timing belts for an ford escort 99?
I was looking at the 1999 Ford Escort scheduled maintenance guide and the
Gates website ( they make timing belts etc . ) and both show to inspect the
timing belt at 120,000 miles , replace if necessary ( that applies to both the 2.0
liter SOHC and DOHC engines )
The timing belt should be changed every 60,000 miles. Most belts will still look like new at 60,000 miles. They seem to want to break at 100,000 miles. Nothing bad will happen if it breaks other than a tow to a mechanic. This is true if you have a non-interference engine BUT if you have an interference engine and the timing belt breaks the engine can destroy itself in a moment.
A timing chain does not need to be replaced. Sometimes they can go bad and will make noise, or can get a bad link, requiring replacement. Timing BELTS require periodic replacement because they are rubber and wear out over time. Chains are good until they experience mechanical breakdown due to excessive wear.
