What is the torque on dual overhead cam bolt?

The torque specification for the rocker shafts on the 2001 Hyundai Accent with the 1.5L single overhead cam engine is 18-20 lb-ft. The proper torque sequence is as follows:

1. Tighten the bolts to 8 lb-ft in a crosswise pattern.
2. Increase the torque to 15 lb-ft, again in a crosswise pattern.
3. Finally, tighten the bolts to the full torque of 18-20 lb-ft, again in a crosswise pattern.

Make sure to use a torque wrench and follow the sequence carefully to ensure proper tightening and prevent damage.

The good news is you can use the same data the dealers use the bad news is, it is not free. Hyundai Service Website (hyundaitechinfo.com)

renew bolts
stage1- 30NM
stage2-90deg
stage3-individually slacken off 360deg
stage4-30NM
stage5-90deg

crank pulley bolt-142NM
cam sprocket bolt-88NM

i like to help people like you that give engine codes it makes it so much easier

The torque for cam is 12nm (105 inch lbs.) You can also find it online if you ask, it will direct you to the answer.

First torque them in sequence to 13-16 ft.lbs.then in sequence to 85-95 degrees next do the same thing again torque to 85-95 degrees.

Here's what the shop manual states:

30 Nm (300 kg.cm, 22 lb.ft)+90°+Release all bolts + 30 Nm(300kg.cm, 22 lb.ft)+90° In this instance you don't have a 'Torque to Spec"... you have a "torque to YIELD' In this specification, initially torque the head bolts to 22 lb ft... then turn each and additional 90°, then loosen each and REDO to the same specification = 22 lb.ft)+90° (you're actually crushing the head gasket TWICE and stretching the head bolts TWICE.

A dual-overhead-cam 4-cylinder engine powered base Probes in 1993, developing 115 horsepower. The GT coupe held a 164-horsepower V6, also of dual-overhead-cam configuration. Both engines are Mazda designs. No more turbocharged engines were available. A 5-speed manual transmission was standard; 4-speed overdrive automatic optional. Except for a slight horsepower/torque boost in 1995 for the 4-cylinder engine, and a mild V6 torque increase the year before, powertrains saw no change in this period.



Hope this helps (remember to rate this answer).

The Head bolts are located below the cams, so you have to take the cams out to get to the bolts.
The torque specs for the head bolts in sequence is 20, 40, then end at 63ft lbs. Be sure to apply anti sieze or dip the head bolts in oil, before you torque them down or you might pull out the threads. (Not a good thing TRUST ME!)
Hope this helps.

Single overhead Cam - 16 ft lbs. Dual Overhead Cam - 200 in lbs taken from Haynes Repair Manual. Good Luck.
