Make sure the engine is completely cool before starting this DIY. Working on a warm engine increases the risk of damaging components as well as raises the chances of burning yourself.

Disconnect the vehicle batteriy's negative terminal to avoid short-circuiting electrical components.

We will need to remove the cabin air filter, HVAC cowl and all covers in the way of accessing the main engine cover.

Unlatch the engine wiring harness by firmly pulling the three latches free of the HVAC cowling.

Remove the ECU cowl and brake reservoir covers by gently prying the two retention clips on the side free until the cover can be removed from the engine bay.

Remove the 8MM cowl screw located underneath both covers.

Remove the 4 8MM cabin air filter screws using a socket / wrench.

With all 4 screws removed, carefully lift the cabin air filter out of place.

Unlatch the windshield washer line from the cowl by pulling the metal retention clip off of it's resting place.

Release the rubber grommet (white circle) from both sides of the HVAC cowl by simply pulling it free.

Release the electrical connector fixed to the HVAC cowl by pressing in the retention clip and pulling it free. Depending on the year, make and model, your vehicle may have 2 of these connectors. 1 will be located as shown, the other closer to the brake fluid reservoir.

Unclip the 3 sets of clips holding the engine witing hose in place to the bottom side of the HVAC cowling.

Pull the HVAC wiring hose free from the underside of the cowl.

With all connecting points free and loosened, carefully remove the HVAC cowl ensuring you do not hit it into any of vehicle.

Remove the three 5MM allen screws that secure the engine cover.

With all 3 screws removed, the engine cover can now be carefully lifted out of place.

Unlatch the crankcase breather hose by depressing both of the side clips and pulling it from the valve cover.

If the push clips can not be depressed properly, break the hose off and rotate the connecting point. This will enable greater access to the hose clips.

Each of the hose connections has two retention clips (white arrows) that can be pressed in to release the hose.

Using a metal pry bar [or two if available], pry against the push clips on either side (white arrows) while leveraging upward to disconnect the hose. Take care not to damage the intake manifold side of the connecting point.

Using a metal pry bar in the same way, pry against the push clips on either side (white arrow). If a pry bar cant reach the tabs, use a flathead screwdriver and hammer to break the tabs off of the hose side. Again, take care not to damage the intake manifold side of the connecting point.

With all three connecting points loosened, wiggle the old hose from the engine bay. Ensure no pieces are left in the engine as this could cause a fire hazard.

With the new hose fitted into the engine bay, line up the hose and intake manifold connecting points. Use a metal pry tool to press down against the thicker [non-ribbed] plastic portion of the hose until the hose can audibly be heard snapping into place. Gently pull on the hose to ensure it's fitted and doesn't pop off.

Using the same metal pry tool, leverage the thicker [non-ribbed] plastic portion of the hose in the direction of the white arrow, until the hose can audibly be heard snapping into place. Gently pull on the hose to ensure it's fitted and doesn't pop off.

With both bottom connecting points snapped into place, press the top portion of the hose firmly into the valve cover until it snaps into place. Gently pull against the hose to ensure it's fitted properly.

After new crankcase breather hose is firmly installed in place, test start the vehicle and allow to idle for roughly 5 minutes observing no rough idles or check engine lights appear.

Now that the vehicle is running properly, the cabin air filter, engine cover and all other components removed or disconnected can be re-installed.

Good job replacing your crankcase breather hose without having to remove the intake manifold! This DIY method takes a bit more precision and patience, but overall saves you money from needing to replace the intake manifold gaskets and remove more complex parts. Ensure you keep an eye on your engine for any possible signs of vacuum leaks from the hose not ebing fully secured.
