Thread: Ventilation piping gap Puma Defender

Or stuff it underneath the cowl, on top of the grille ?

Yes, I could just cut the material to size.
BTW I removed my grille as it seemed redundant and the cowl fitted better without it.

Incidentally, back to the OP and it appears that my bodgy job of sticking foam insulation around the gap appears to have worked, as the air through the ventilation is certainly cooler, and the air con isn't struggling as much. I had to do two long runs at the weekend so I was monitoring to see what happened as the engine bay heated up, but it seems OK.
I still think I haven't completely closed the gap, so I'm going to have another fiddle, if I can get my fingers around the back of the piping at the gap.
Next week, after I get paid, I'm going to order the second snow cowl. They're only about $40-50 so it seems like a good idea to assist with venting hot air on the driver's side. It can't make it worse, plus it will make the vehicle look balanced with one on each side, as Tombie said.

I've got a snorkel sock that fits over the snorkel on my intake, it makes a significant difference to the amount of dust that comes in. The snorkel also stops the hot air being sucked into the heater duct by giving some positive pressure at speed.

Borrow someone's kids or wife to do it...
You will need small soft hands....

Hmnnnnnn. Thanks for sharing

I may do something similar but this will surely destroy the aerodynamics and worse the fuel economy....

Cheers

Did you just write Aerodynamics in a Defender thread? 🤪

It is pretty funny watching from a cafe across the street the bloke trying to figure out what the two snorkels feed, looking under the guard and walking around the other side of the vehicle to check out if there's anything he can see under that guard. Has happened a couple of times now.....

I'm thinking Martin said that tongue in cheek.

I hope!
