What is the posistion for the timing chain for a 1998 acura tl
Curtis: The Acura TL had two different engines in it. Neither used timing chains.
Settings for the timing belts are as follows: this is on the 2.5 liter.
Before you pull it apart, break the front crank pulley bolt loose.
Line up the white mark on the pulley with the pointer on lower cover.
Berfore you pull the crank pulley, break the cam bolt loose.
Recheck the crank pulley marks with pointer. Remove the obvious to gain access to the timing covers.
NOTE, if you look at the cam gear will have the word "up" should be on the up side. There should be notches cut on opposite sides of the gear which should line up perfectly with the timing cover... You should have a timing belt tensioner still in place before, when you do your initial check.
After you remove the crank pulley and the timing cover, the woodruff key should be at 12:00 PM
You will also see if you look closer, at the gear. a punch mark, above the woodruff kny. There is an arroe cast into the block. This assures you that you have maintained alignment.
On the 3.2 V-6 same scenario. Remove all the **** surrounding your access to the timing covers and belt. After getting the front crank bolt loose, realign the timing marks to bring it to TDC (Woodruff key @ 12:00 PM) In changing the timing belt on this engine, remove the belt tensioner and you should be able to install the belt without removing the gears.
The right (passengers side) cam gear has a notch cut in the outside edge of the gear. There should be an alignment mark just behind it if you have it set fairly close.The drivers side should be the same.On both engines, make sure when you install the belt, the drivers side is ligned up perfectly and the belt is tight between the left side of the sprocket and the crank gear. Run the belt over to the other cam, making sure the cam is still ligned up. the belt without the tensioner will be real sloppy. Get a small clamp you can place to hold the belt in place on the right cam until you have the tensioner in place.
In checking on both of these engines, they are not intereference fit motors, in short, they are not prone to bending valves. Good luck.
