top dead center for cyl. #1 is when the notch on the crank lines up exactly with "0" on the timing cover. if you have the upper timing cover off, the marks on the cam gears should be up and in line with the marks on the metal plate behind the gears. if all those things are lined up, the engine has cylinder #1 at TDC of the compression stroke. to set the distributor at this point, find where the #1 plug wire is. trace its location down to the distributor body and mark on the distributor EXACTLY where the electrode is. (you need to be able to see where its supposed to be because you cant install the distributor with the cap on) now remove the dist. cap. before installing the distributor, turn the crankshaft counterclockwise just a little to line up the notch on the crank to the 10 deg. mark. now install the distributor so when its fully seated, the rotor points directly at the mark you made on the distributor. (you may have to remove and remesh the gears a few times to make this work, you also have flexibility with the built in adjustment on the dist. itself) this will be very close to correct ignition timing. after the engine is running it should be checked with a light.
Yes , the 4.0 liter V6 engine in a 2003 Toyota 4 Runner has a timing CHAIN
The timing belts on older Toyota 4Runner models are rated to last approximately 60000 miles. Going to long without changing them can result in a damaged engine.
Your 2004 Toyota 4Runner has a timing belt if it is a V8. This belt must be replaced every 90,000 miles. Warning: This is an interference engine. Severe engine damage will be done if the belt breaks. If you have a V6 then it has a chain which should last the life of the engine.
Yes , it has a timing belt according to the Gates website ( they make timing belts etc . )
A chain. The only engine Toyota makes anymore with a timing belt is the V8 engines in the Trucks, Tunda and Sequoia and 4Runner
Yes , the 4.0 liter V6 engine in a 2003 Toyota 4 Runner has a timing CHAIN
It should last the life of the engine and is normally replaced during an engine overhaul.
The 2001 3.4 L V6 Toyota 4Runner has a cam belt. The belt must be replaced every 90,000 miles. Warning: This is an interference engine. If the belt breaks you will have serious engine damage.

It does not have a timing belt. It has a chain..all 2003 Toyota Corolla Trims S, CE and LE have the same engine, the 1.8Liter 1 ZZ FE, The only engine Toyota makes anymore with a timing belt is the V8 that comes in the Tundra, Sequoia and 4Runner
According to the Gates website the 4.7 liter V8 in a 2003 Toyota 4 Runner has a timing BELT , it is an interference engine , change the belt at 90,000 miles , and it also has a water pump that is driven by the timing belt
