Freelander 2 eating its intercooler turbo hose

HeywoodFloyd · Nov 20, 2023

I'm about to change the lower intercooler hose, the long one. This will be the 2nd time I've replaced it since owning this car.

Basically, over time one of the belt driven wheels that's right near the hose, slowly eats away at it, until I get a hole.

When fitting the hose, there's a reasonable gap between the hose and the wheel, and I can't myself push the hose against the wheel once fitted, so I can't work out what's going on here... What event in the car occurs to bring these 2 items together and cause this?

any ideas? I'd rather not keep replacing his hose, it's a pain to do let alone the cost.

Dunno the setup on the F2, is that to or from the intercooler?

Is the intercooler blocked/restricted or summat, to much boost from the turbo?

Hi there, when the turbo is active the boost hoses expand due to the internal boost pressure. This will close the gap making them rub. Stuff like this doesn’t usually happen unless someone has disturbed a clip/mount/bracket that holds it in place. Have a good look around the area there will be something off. If you can’t spot anything use a big cable tie or something to hold the boost hose back away from the pulley. Ideally you want a 10-15mm gap minimum. Often aftermarket hoses aren’t quite the right size or shape. Original parts are often better fit.

Yeah there's a white plastic clip that was already there that I've been using but maybe it's just not doing it's job. I'll add in some cable ties too!

You could also cut a section of the old hose that’s coming off and wrap it around the new one at the problem area and secure it with ties or something. The extra protection could save you some cash. Maybe check again a few days after fitting for contact marks. Will confirm whether you’ve nailed it this time or if it needs tweeting.

Is the lower support band for the hose in place? Have you checked that the lower engine torque reaction bush is in good condition?
The only time I've seen the boost hose touch the AC compressor pulley is when the hose support band isn't fixed to the front subframe, or the lower reaction bush has failed due to oil deteriorating the rubber.
Here's mine. No issues with contact on mine.
