Where can you find torque specs for the head bolt a quad 4 2.3l dohc?

You won't find a single, universally applicable torque spec for the head bolts on a 2.3L Quad 4 DOHC engine. The torque specification depends heavily on the *specific year and model* of the vehicle the engine is in. Different years may have used slightly different head bolt designs or materials, requiring different tightening procedures.

To find the correct torque specs, you need to consult a repair manual specifically for your vehicle's year, make, and model. These manuals often include detailed torque specifications and tightening procedures, sometimes even specifying a multi-stage tightening sequence.

Here's where you can find a suitable repair manual:

* Online Retailers: Sites like Amazon, eBay, and others sell both physical and digital repair manuals (often called "factory service manuals" or "FSMs"). Search using the exact year, make, and model of your car.

* Auto Parts Stores: Some auto parts stores (like AutoZone, Advance Auto Parts, etc.) might have access to online repair information, though it may require a subscription or in-store purchase.

* Online Forums: Forums dedicated to your specific vehicle model might have members who can provide the information or point you to a reliable resource. However, always double-check information found on forums against a reputable source.

Caution: Using the wrong torque specs can lead to serious engine damage, including warped heads, cracked blocks, or blown head gaskets. Always use the correct specifications from a reliable source. If you're unsure about any aspect of this procedure, it's best to have a qualified mechanic perform the work.
