Tim Stanners takes us through a professional installation of an Airtec snorkel on this 150 Prado.

 

I reckon I’m pretty handy when it comes to DIY type things. An electrician by trade, I’ll give most things a go. But when it came to drilling a 4 inch hole in the side of the car? Well … I’ll let you decide!

 

First, you’ll need a few tools:

– A drill and assorted hole saws and drill bits.

– Wheel Brace

– Spanners

– Screw Drivers

– Car Polish

– Snorkel cut-out templates

– Tape

– Scissors

– Loctite

– Acrylic or Enamel Paint and a small brush

– Caulking gun and a tube of bond and seal compound.

 

All of the tools and parts laid out, ready to start the job.

 

Step 1: Check all your Snorkel Components and cut out the supplied template as per instructions.

Step 2: Check the template against the back of the snorkel to make sure its the right template for the snorkel (and ensure the template holes match the snorkel holes).

Step 3: Polish the outside panel / guard where the snorkel will be fitted (this ensures a clean surface where no grit exists between the snorkel and the panel).

Step 4: Remove the wheel and any inner guards ensuring the vehicle is stabilised with Chassis stands.

Step 5: Remove the lid of the air filter box, the air filter and the air box itself.

Step 6: Block the air intake with a clean rag to ensure no dirt or metal filings end up in your engine.

Step 7: Tape the template to the side panel of the car and re-check the snorkel by placing it over the top of the template.

 

There are few times when the old adage of ‘measure twice, cut once’ is more important than a snorkel install!

 

Step 8: Loctite the supplied snorkel studs into the snorkel.

 

Step 9: Once you’re confident you have the template in place, centre punch all marked holes (including the top pillar mount).

Step 10: Check under the panel / guard for any possible wiring behind where you’re about to drill.

Step 11: Now…..take a deep breath and using a very small drill bit, pilot drill all marked stud holes.

 

It’s important to drill pilot holes after centre punching, to ensure the holes are as accurate as possible.

 

Step 12: Drill remaining stud holes to correct size as per template and de-burr.

Step 13: Take another breath and using the correct size hole saw, cut out main hole and de-burr.

 

 

Step14: Paint the inside of each hole with enamel paint (ensuring all clean exposed metal is covered) and let dry.

Step 15: Insert the inner snorkel ducting through the main hole.

 

When the holes are drilled, deburring (with a correct tool) and retouching with paint is an important step for a trouble-free life.

 

Step 16: Fit the supplied gasket over the inside of the snorkel housing.

Step 17: Fit the snorkel housing using the sealant around all joints and the top pillar mount, ensuring any hose clamps are tightened with a screwdriver.

Step 18: Clean off all the swarf and metal filings using a vacuum and remember to remove the rag from the air intake.

Step 19: Refit the air box and seal using sealant around the ducting entry.

 

 

Step 20: Refit the air filter and lid.

Step 21: Refit the inner guards and the wheel.

Step 22: All done! Leave the vehicle stationary for an hour or two to allow the sealant to dry.

 

With the snorkel being supplied by TJM, we had the opportunity to install it ourselves. Talking the install through with our mates at Penrith Offroad Warehouse and weighing up the small professional fitting costs vs the possible cost of making a mistake ourselves, we made the call to have the install professionally done and were glad we did. Hopefully, we’ve called out some little tricks of the trade which will allow you to do the same! Good luck!
