Is the EJ22 an interference engine?
The compression ratio of early EJ22 is 9.5:1. Unlike the 2.5, the 2.2 engine is not an interference engine. If the belt breaks or jumps timing, the engine probably will not sustain any internal damage.
Can a loose timing belt cause the car to overheat?
Yup, if it’s loose and it’s run by the timing belt. You didn’t list an engine size so that’s a generalization but it applies to any engine with a water pump that is one of the idler pulleys. helpful? Although the timing belt does operate the water pump, if the belt slips in any way the engine will cease running which makes it a moot point.
Is the valve timing correct on an EJ22?
Even though the crank shaft makes two revolutions for every turn of the cam shafts if these marks are lined up as shown the valve timing will be correct.
How do you change timing belt on Subaru EJ22?
What they did was rotate the crank 90 degrees clockwise – which moves the cam gears 45 degrees clockwise. In this position all of the gears can be moved quite easily but will stay put while you fit the new timing belt.
Can a timing belt cause a water pump leak?
It can’t cause overheating unless it’s just a water pump leak that doesn’t effect the timing belt so to answer your question, no, a timing belt cannot cause overheating. helpful? Happened to my 3.0L Grand Voyager with a freshly rebuilt engine. The tensioner pulley is spring-loaded to set the tension, then a nut is tightened to hold it there.

Where is the crank gear on an EJ22?
This picture shows the crank gear, on the left, at top dead centre (TDC) on cylinder #1 – the small arrow on the face of the gear is pointing to the small mark in the case.
Where are the timing marks on a timing belt?
Here the valve timing marks are in the correct position for installing a new belt – note that the crank is rotated 90 degrees and the cam gear is rotated 45 degrees from the TDC position.
