I changed the distributor drive
Hi, the procedure is pasted below. Ignore the timing marks and just verify you are at TDC of the compression stroke on the #1 piston. You can tell compression versus exhaust stroke by plugging the spark plug hole with your thumb while turning the crankshaft (there will be no pressure on the exhaust stroke). Please let me know if you have more questions, and thanks for using FixYa.
Timing Disturbed
-
Remove the No. 1 cylinder spark plug. Turn the engine using a
socket wrench on the large bolt on the front of the crankshaft pulley.
Place a finger near the No. 1 spark plug hole and turn the crankshaft
until the piston reaches Top Dead Center (TDC). As the engine approaches
TDC, you will feel air being expelled by the No. 1 cylinder. If the
position is not being met, turn the engine another full turn (360
degree). Once the engine position is correct, install the spark plug.
-
Align the cast arrow in the distributor housing, the driven gear
roll pin and the pre-drilled indent hole in the distributor driven gear.
If the driven gear is installed correctly, the dimple will be
approximately 180° opposite the rotor segment when it is installed in
the distributor.
NOTE
Installing the distributor 180° out of alignment, or locating the
rotor in the wrong holes, may cause a no start condition or can cause
premature engine damage and wear.
-
Make sure the rotor is pointing to the cap hold-down mount nearest the flat side of the housing.
-
Using a long screwdriver, align the oil pump drive shaft in the engine in the mating drive tab in the distributor.
-
Install the distributor in the engine. Make sure the spark plug towers are perpendicular to the centerline of the engine.
-
When the distributor is fully seated, the rotor segment should be
aligned with the pointer cast in the distributor base. The pointer will
have a -6'' cast into it indicating a 6 cylinder engine. If the rotor
segment is not within a few degrees of the pointer, the distributor gear
may be off a tooth or more. If this is the case repeat the process
until the rotor aligns with the pointer.
-
Install the cap and fasten the mounting screws.
-
Tighten the distributor mounting bolt to 18 ft. lbs. (25 Nm).
-
Engage the electrical connections and the spark plug wires.
Replace heater bypass valve on 2003 Chevy astro
What do you want to know? It is not too difficult to replace this valve. It is located high enough that you will not need to drain the coolant. However, do not remove the valve when the vehicle is hot or when the cooling system is pressurized. Let it cool for a couple of hours.
What side is bank 1 on a 2003 chevy astro v6
Don't know if things have changed, but in general in my time any Vee-engine, #1 cylinder was always right bank (ie to your left when you are standing in front of car facing engine bay) and front most cylinder.)
I am in a RHD car market, but I doubt it makes any difference to the general rule on this.
