Looking for a picture of the bolt sequence for the cylinder head on a 1991 acura 1.8l dohc.

Go to autozone.com and become a member of their web-site. It is FREE. You can then access repair info for your vehicle. There are repair manuals that show pictures and everything. I will look for your torque specs and picture.

Clean the cylinder head bolts, apply sealer to the threads, and hand-tighten.

Tighten the cylinder head bolts:

1. M11 cylinder head bolts first pass in sequence to 30 Nm (22 ft. lbs.).
2. M11 cylinder head bolts second pass in sequence + 90 degrees.
3. M11 cylinder head bolts (1,2,3,4,5,6,7,8) + 90 degrees
4. M11 cylinder head bolts (9 and 10) + 50 degrees
5. M8 cylinder head bolts (11,12,13,14,15) to 30 Nm (22 ft. lbs.). Begin with the center bolt (11) and alternating side-to-side, work outward tightening all of the bolts.
   NOTE The cylinder head gasket displacement can be verified by markings visible on the underside of the right gasket locating tab. Some 4.8/5.3L head gaskets may have 53 stamped onto the locating tab. Some 6.0L head gaskets may have 60 stamped onto the locating tab.

I'm not sure what engine you have in your 95 grand am SO I will give you both the 4cyl and 6cyl Specs. Also you didn't ask for the torque sequence. I will include that as well for both. 2.3 DOHC Quad 4cyl: Torque sequence---> front ' 7 3 1 5 9 ' of engine ' 8 6 2 4 10 ' Step 1: torque bolts 1 thru 6 (26 Ft/Lbs & 90 degree turn) Step 2: torque bolts 7 & 8 (15 Ft/Lbs & 90 degree turn) Step 3: torque bolts 9 & 10 (22 Ft/Lbs & 90 degree turn) Recheck final torque in sequence *** CAUTION *** This engine uses "Torque To Yield" (TTY) head bolts that means they permanently stretch during the initial installation. New head bolts must be used when cylinder head is replaced or re-installed in order to obtain proper torque. 3.1 liter V6 Torque sequence--> ' 6 2 3 7 ' ' 5 1 4 8 ' Step 1: torque bolts in sequence to 33 Ft/Lbs Step 2: turn an additional 90 degrees Recheck final torque in sequence *** CAUTION *** This particular engine uses "Torque To Yield" head bolts(TTY) (that means the bolts permanently stretch during the initial installation.) You MUST use NEW head bolts when replacing or reinstalling the cylinder head in order to obtain the proper torque.

Thanks for using FixYa.

To install:

1. Install a new head gasket on the engine, making certain it is positioned correctly. The cylinder head dowel pins and the oil jet must be in place. Refer to the illustrations if necessary.
2. Install the head. Lower it straight down onto the block, aligning it correctly.
3. Apply clean engine oil to the bolt threads and the contact face of the bolt head. Install the head bolts finger-tight.
4. On all models except 1988-89 DOHC Prelude and 1992-95 Preludes with 2.3L and VTEC engines, tighten the head bolts following sequence A. On 1988-89 DOHC Preludes, use sequence B. Use sequence C on 1992-95 Preludes with 2.3L and VTEC engines.
   1. On 1984-89 Accords and 1984-91 Preludes, tighten the bolts in two passes. The first pass should bring the bolts to about 22 ft. lbs. (30 Nm). On the second pass, tighten the bolts to their final torque of 49 ft. lbs. (68 Nm).
   2. On 1990-93 Accords, tighten the bolts to 29 ft. lbs. (40 Nm) on the first pass, 51 ft. lbs. (70 Nm) on the second pass, then tighten the bolts to their final torque of 78 ft. lbs. (108 Nm).
   3. On 1994-95 Accords and 1992-95 Preludes, the bolts are also tightened in three passes. Tighten the bolts to 29 ft. lbs. (40 Nm) on the first pass, 51 ft. lbs. (70 Nm) on the second pass, then tighten the bolts to their final torque of 72 ft. lbs. (100 Nm).

18. Connect the throttle control cable and/or accelerator cable at the throttle body.
19. Connect the fuel lines.
20. Install the brake booster, PCV and charcoal canister vacuum hoses.
21. Install the air cleaner and intake duct.
22. Refill the engine coolant. It is recommended that the engine oil be changed whenever a cylinder head is removed.
23. Connect the negative battery cable.
24. Start the engine, allowing it to idle. Bleed the cooling system. Check the work area carefully for any signs of fluid leakage or any indication of the timing belt rubbing or slapping the covers.
