Strut to Steering Knuckle Bolt 148


Thought it was 126...I don't have any literature to back me up, but iirc it's 126 ft/lbs. If not, then i've been wrong for quite some time...Hahaha...

Anyways, Great reference tool, wolfman!

[freakerz]

From Hayne's:

Strut-to-suspension knuckle bolts/nuts
1995 and earlier .... 148lbs
1996 ................... 126lbs

Enjoy! I'll check others later ;) since I'll make this a guide on csq.com :)

sorry i'm confused, I am not sure what exactly the list is saying. If someone could explain that would be really helpful.
thank you.

thank you.Torque is the force used to rotate things. Our cars have lots of bolts and nuts. If we don't tighten them enough then they might loosen. If we tighten them too much then we can damage things. Wolfman provided lists of how tight bolts and nuts and stuff need to be tightened. The units for torque are foot-pounds (as in distance and weight) for SAE and newton meters for metric. There are other units for torque too such as inch-pounds (12 inch-pounds = 1 foot-pound), newton-centimeters, millinewton-meters, etc. and these are less common. We use a "torque wrench" when applying force to rotate bolts and such. Torque wrenches come in a few varieties and they range in price from between $10 and to amounts exceeding $200. I'd guess that a decent torque wrench costs between $30 and $80. Anybody that does the most basic car maintenance to include swapping their wheels/tires around should have a torque wrench in their tool collection.

right on, thanks.
i was thinking like the power in your engine, but thanks for clearing it up. makes sense

[eRic 02sc2]

(Torque x Engine speed) / 5,252 = Horsepower
Torque is a force that tends to rotate or turn things. We generally express force from an engine or motor in pound-feet and torque needed to tighten a fastener in
foot-pounds.

What is the torque specification for the intake manifold retaining bolts on a 2000 Saturn SL2 with the new plastic intake? The post above indicates 22 ft lbs but that is the same spec as the cast iron intake. I would think it might be lower for the plastic intake. Thanks.

[ssicarman]

The intake manifold-to-head are 13 N·m (9.5 lb ft).

The EGR pipe-to-cylinder head is 25 N·m (19 lb ft).

[David 93 SL2m]

The torque spec for the thermostat housing bolts is 22 ft. lbs.

As always, be sure to use a 6-point socket as the 12-point sockets are likely to "round" the hexagonal heads of the bolts.

so does a torque wrench have an adjustable torque setting like an electric screwdriver to prevent a bolt to be over tightened?

Depends on the type of torque wrench. Clicker types do. Beam types don't.

There are two common types of torque wrenches for home shop use; the "beam" type and the "clicker" type. The beam type torque wrench is shown in Figure 1c and is the least expensive torque wrench. The beam wrench works by the beam bending in response to the torque applied as shown in Figure 2c. This type is very simple, reliable, and accurate, and there is little that can go wrong with it when used properly. When tightening a bolt, make sure to only apply force in the center of the handle. This allows the beam to bend in the manner it was designed to indicate the correct torque. Do not over torque the wrench or the beam may bend permanently. Do not drop the wrench because rough handling can bend the pointer arm or pointer. If the pointer is bent, it can be bent back to the center without affecting accuracy. If the beam is bent it cannot be bent back.

Figure 3c shows the clicker torque wrench, which is sometimes called a digital wrench. A clicker torque wrench works by preloading a "snap" mechanism with a spring to release at a specified torque. When the mechanism releases the ratchet head it makes a "click" noise as shown in Figure 4c. The torque is set by rotating the handle until the desired torque is shown in the window. Older clicker wrenches have a micrometer style scale along the handle instead of a window. The clicker wrench is much easier to use because it is easy to set the desired torque and just pull until you feel the click. The ratchet head also makes it easy to use in confined spaces. It is good practice to set a clicker wrench to its lowest setting before putting it away to prevent the spring from taking a set. Avoid rough handling and dropping because it can damage the mechanism. Do not use the torque wrench to loosen tight fasteners since this may damage the calibration.

hey you rock thanks!

Lower control arm to frame as per Autozone for 1991 thru 1998.
"Tighten the cradle bolt to 92 ft. lbs. (125 Nm), then tighten the cradle nut to 74 ft. lbs. (100 Nm)."
