According to Gates Rubber and Preferred Components, two timing belt manufacturers, Mazda has several engines that are "interference-type" engines. On some Proteges, the 1.6 and 1.8 are safe, but the 2.0 (1991cc DOHC) most definitely will cause major damage if the timing belt breaks. Mazda recommends T-belt replacement every 60,000 miles on most of their engines, interference or not. The two belt manufacturers I mentioned above have details on engine specifications from all auto makers available on their websites.
Both the four cylinder and six cylinder engines are non-interference so if the timing belt breaks there will be no damage to the valves. The 1993-2001 four cylinder engines all use the same block and heads as do the six cylinder engines.
No , it is not an interference engine
by what do you mean interference engine?
No , the 1.8 liter 4 cylinder in a 1999 Mazda Protege is not an interference engine
NONinterference. belt breaks, nothing hits NOT WHAT MAZDA said. !! 99 2.5L is most certainly INTERFERENCE and I confirmed with 2 NON dealer shops. wanna bet? i will even give you odds. 100 to 1. and those 2 shops dont know their butts from a hole in the ground
I researched this as I own a Mazda Protege with a 2.0 DOCH engine. I found a file that list all interference engines and timing belt requirements. The Mazda 2.0 L is listed as a interfrence engine with a timing belt change listed at 105,000. I just changed my timing belt at 121,000. File that list engine can be found if you google (power grip interference engine)
You are extremely fortunate. The 4 cylinder & V6 on the 2000 Mazda 626 are NOT interference engines. There should be no damage.You are extremely fortunate. The 4 cylinder & V6 on the 2000 Mazda 626 are NOT interference engines. There should be no damage.
Yes, the 2003 Mazda Protege is equipped with an interference engine. In an interference engine, the timing of the valves and pistons is such that if the timing belt or chain fails, the pistons can collide with the open valves, potentially causing significant engine damage. Therefore, it's essential to maintain the timing belt and replace it according to the manufacturer's recommended schedule to prevent failure.
The Mazda RX-8 is equipped with a Wankel rotary engine, which is a unique design that does not fall into the traditional categories of interference or non-interference engines commonly associated with piston engines. In a rotary engine, the design allows for the rotor to move without the risk of contact with other components in a way that would cause interference. Therefore, if a rotary engine fails, it generally does not lead to the catastrophic engine damage typical of interference piston engines.
On a 2003 Mazda Protege it must be changed at 105,000 miles. This is an interference engine and as such if the belt breaks serious engine damage will occur.
A Mazda B3000 truck does not have a non interference engine. These engines are designed to survive catastrophic timing failures due to lower tolerances.
where is the thermostat on a 1999 mazda protege?
