Broken timing belt what is the likelyhood of engine damage
On engines that are interference, if the timing belt skids for just a notch, the piston can crash to the open valve and this can lead to severe engine defect by means of bending the valves and breaking the pistons. so it is possible that dammage has happened
Valve stuck in a pistons and you'll need a new engine.
if the timing belt is broken it needs a replace ment
if you are going to undertake this job by yourself, be very aware that the SOHC & the DOHC engines are interference engines by design. This means that timing alignment is critical to the installation. if you experience no compression readings or even try to crank that engine over, it will do damage to the valve train or the piston surfaces themselves. also note that if the engine experienced the failure of the timing belt while running, it is important to check the valve train components .
Mitsubishi says every 60,000 miles it should be replaced.
thanks.
The coolant bottle is a coolant overflow tank. Refilling the overflow tank does not necessarily refill the entire cooling system. To refill the cooling system, the radiator cap must be removed and coolant added. This must be done with the engine cold. Do not remove the radiator cap when the engine is hot or you will be scalded. There is a very good chance that the water pump leaked most of the coolant out of the system. With 63,000 miles, it is a good idea to do the timing belt with the water pump. As far as cost, check reputable service centers in your area and compare costs.
I am a mechanic, this is an interference engine, this means the valves can get bent from contact with the engine pistons, chances are there is damage, but the only way to know is to go ahead and put the belt on and turn the engine by hand one revolution, if it spins very easily the you have bent valves, no compression, if you are not sure then still do one full revolution and then and only then try to start it, if it runs smooth you are home free, if it misses then a valve or valves is bent. It is very unlikely that any piston damage has occurred, so pulling the head and doing the valves will fix it.
No chance, just replace the belt.
