Yes, plastic coating on steel and not just the 455. Maybe for less chain wear or noise reduction. Every one I've ever seen when engine was tore down was cracked or broken.
This website does not offer pictures. The 3.8L has never had plastic gears.
No, because it does not have a timing belt, it has a chain that should last the life of the engine.
Probably one with a factory 2.5L I4 engine since hardly anyone ever bought one with that engine
It is located on the side of the engine block. The purpose of the knock sensor is to retard engine timing When there is an engine noise. It is a rare case that one ever goes bad.
Ford Falcon 6 is one of the most famous models ever produced by the company. The engine uses neither a timing belt nor a timing chain, instead it uses a timing gear which is considered to be long lasting.
Generally it is recommended replacing the timing belt and water pump on a 4 cylinder Subaru engine at 10 years or 100,000 miles, which ever comes first.
Correct timing is what ever the manufacture recommends.
There is no timing adjustment. Put the 8mm bolts through the holes in both the cam sprockets at the correct points(bottom) and the mark on the crank gear with the mark on the chain housing(UP), and that is all you can do as far as timing. Everything is 0 degrees TDC. If this engine ever gets too far out of time, it will be a disaster for the engine.
If you have to ask, you should take it to the shop. Done wrong, timing belts can cause a lot of trouble. I would recomend you get a Chilton's manual from the Library. However, it can be explained simply. The belt is one the side of the engine under a plastic cover. "Simply" remove the cover, release the tensioner and pull of the belt (or what ever is left of it). Install a new belt and retension. !!!WARNING!!! Engine timing must be exact. The Chilton Manual will explain the timing marks found on the sprockets. REMEMBER ON THE 1990 THEIR ARE THE TWO BALANCE SHAFTS WITH ANOTHER BELT BEFORE YOU EVEN GET TO THE TIMING BELT, AFTER THAT THE PROCEDURE IS BASICALLY THE SAME AS FOR A LATER 4 -BANGER HONDA(96-2000)
belt driven engine 10 years or 100k which ever comes 1st
No valves should tick on any automobile what-so-ever. When there is valve ticking noises coming from an engine that usually means the timing of the engine is off and you should get it timed again. The timing is when you set the spark plug to go spark at a certain point in the cylinder. Refer to a dealer for correct timing. A good rule of thumb is to check the life of your timing belt if your vehicle has one.
First of all a 2003 Tahoe has a timing chain. And the answer to your question is a serpentine belt is what is on the front of your engine, It runs the water pump, power steering, Alternator, A/C and what ever else is hooked to the front of the engine. A timing belt is what hooks the crank to the camshaft and has Gogs on it that runs in the gears. A serpentine belt has grooves in it so it will stay on the pulleys.
