What happens if Cambelt snaps?

If the cam belt snaps while you’re driving, it could be very dangerous. The engine could seize up, causing steering and brakes to fail. The pistons can hit the valves in the cylinders, damaging the engine. A non-interference or free-wheeling engine won’t suffer as much damage, but still might sustain some.

Is the Fiat Punto a non-interference engine?

I’m fairly certain the older Punto 1.2 engines are non-interference, that is the valves will not hit the pistons if the timing belt breaks or slips.

Why would my timing belt snap?

Cars which are usually driven in countries which have a warm, dry climate will often have to have their timing belts replaced more often than those driven in more temperate climates. The dry air causes the rubber to become brittle more quickly and this can cause the belt to crack or snap.

Can timing belts snap?

Over time, timing belts begin to wear out and can fray or tear. This is why they need to be replaced at certain intervals, typically around every 60,000 miles or so. Not only will a snapped belt leave you stranded, but it can bend valves, cause piston damage, and ruin cylinder heads.

Can snapped timing belt destroy my engine?

Will a Broken Timing Belt Destroy My Engine? It depends. Some cars, like Subaru, have non-interference engines, which means that if the timing belt breaks while you are driving, there is no damage to the internal parts of the engine. Other cars do not have this sort of engine and damage results.

Are diesel engines non-interference?

Automobile engines can be classified as either interference engine or non-interference engine types depending on what occurs if piston/valve synchronization is lost. Most import (with higher compression engines) and most car and light truck diesel engines are interference.

What is a non-interference engine?

Put simply, in a non-interference engine, when the piston is at top dead center (TDC), it will never go higher than a fully open valve; that is, the piston can never “interfere” with the valves. Conversely, in an interference engine, the piston could occupy the same space as an open valve.

Can I drive with a bad timing belt?

Your Car’s Engine Won’t Turn Over When your timing belt is broken, you won’t be able to drive your car at all. Oftentimes, the timing belt will break while the car is in motion. This can cause serious damage to cylinder head hardware like rocker arms, push rods, or valves.

How do you know if the Cambelt needs changing?

Visual Check Another way to check whether your cambelt needs replacing, is to take a look at the belt itself. If it is becoming worn, the belt will appear to look glazed or glossy on the underside. This means the rubber is getting hard and will not provide the flexibility the belt needs.

Is there any warning before timing belt breaks?

The timing belt can fail without any prior symptoms, so if you’re within the mileage window, you should go ahead and have it replaced regardless. That being said, sometimes your car will give you a bit of warning that the belt is wearing out.

Is it worth replacing a broken timing belt?

A timing belt is one of those things that’s critical to replace according to the auto manufacturer’s schedule. Most often this will be between every 75,000 and 100,000 miles. Eventually, the belt will break and you may have thousands of dollars in engine damage. It’s simply not worth the risk.
