Pulling this lever will disengage the hood lock, marking the first step towards accessing the engine bay.
But where exactly is this elusive lever located? Rest assured, we’ll guide you through. Here’s how you can find it and how to use it effectively.
Locate the Interior Hood Release Lever
The interior hood release lever is located inside the vehicle on the driver’s side. Common places for the hood release lever include under the dashboard to the left of the steering wheel, along the door frame, or on the lower left side of the dashboard.
Once you’ve located the lever, pull it. This should lift the hood 1 to 2 inches, partially disengaging the hood latch. Bear in mind, the technique lies in the pull.
Pull the Hood Release Lever
Properly pulling the interior hood release lever is key to safely disengaging the hood latch without causing damage. So how exactly should you pull it? You’ll need a firm and steady motion when pulling the hood release lever.
But don’t mistake firm for rough. Even though a firm motion is necessary, it’s equally important to pull the lever gently to maintain the integrity of the mechanism. Combining a smooth, steady, and gentle pulling action is the most effective way to engage the hood release.
Opening the Car Engine Cover
Once the hood release lever is pulled, you’re set to open the car engine cover. But this isn’t simply a matter of lifting it up. You’ll need to lift the hood slightly, release the secondary latch or safety catch, and then secure the hood with a support rod or struts.
Remember, use caution and avoid using excessive force when trying to lift or unlock the hood as this can damage the locking mechanism or hood components. Let’s explore the details of executing this task safely and efficiently.
Lift the Hood Slightly
Following the release of the primary latch from the vehicle’s interior, the hood should be lifted slightly to access the secondary latch. The secondary latch mechanism is generally located under the center of the hood.
To fully release the hood, the secondary latch mechanism will require pressing or pulling, which may vary based on the vehicle model. So, don’t force it. Just lift it slightly and feel for the secondary latch.
Release the Secondary Latch or Safety Catch
The secondary latch or safety catch is usually positioned directly under the center of the hood, but it can sometimes be located off to one side. When preparing to release it, it’s essential to support the hood with one hand, as it may start to open once the latch is disengaged.
To release the secondary latch, depending on the vehicle, you may need to press the latch up against the bottom of the hood, push it to the side, or pull a lever away from the hood. With the safety catch or secondary latch disengaged, the hood becomes mobile and can be secured in the open position for inspection or maintenance.
Secure the Hood with Support Rod or Struts
Having opened the hood, securing it becomes the next important step. The hood support rod holds the hood in place without manual support. If the hood does not stay open on its own, locate the prop rod along the front of the engine bay and insert the tip into the designated hole on the underside of the hood.
Car hoods are secured using a support rod or struts that fit into designated holes or clips on the vehicle’s body or hood. When reattaching a hood support rod, ensure it is inserted into a grommet or clip on the vehicle’s fender.
Certain car models, including some donor car options, come equipped with automatic hood supports and a wiring harness, eliminating the need for a manual support rod. Such a feature simplifies and streamlines access to the engine compartment.
Inspecting the Engine Components
With the hood open and secured, it’s time to inspect the engine components. An engine inspection should include evaluation of the following:
- Air intake system
- Emission controls
- Fuel system
- Ignition system
- Engine block and its internal components such as the cylinder head, crankshaft, camshaft, timing belt, engine valves, and spark plugs.
Inspecting modern engines, including the swinging engine, comprehensively involves assessing:
- Mechanical, electrical, and electronic systems for proper fit and wear, following the service manual specific guidelines
- Securing mounting positions
