Insignia 2.0 CDTI Turbo intercooler hose replacement

Mart34

Hi guys,
Just looking for a little guidance/advice, I've got a split turbo intercooler hose on my insignia, replacement has been ordered. Looks really easy to fit although I could be wrong, is it just a case of removing the old hose and replacing with the new hose or does anything such as the radiator/cooling system need to be bled?

I've used endless amounts of insulation tape which works as a temp fix but doesn't last as it eventually blows thru the tape.


Thanks for any advice

It should just be as easy as swapping the hose. The intercooler takes pressurised air (which is fairly warm) from the turbo and cools it before passing it into the engine. There's no coolant involved. As you've found out, it does need to be robust and properly attached to cope with the boost pressure.

The intercooler hoses are a common fault on the insignia.

It moght be worth changing the boost control valve as well, these are also known to fail, causing overboost, which then pops the hose.

The BCV is about £50 from the dealers and a 2 minute job to change.

The intercooler hose can either be changed through the front nearside foglight or via removal of the bumper.

The bumper is really easy to whip off and the whole job (including removal and refitting of the bumper) can be done by a home mechanic in about an hour.

Just completed replacing the hose, was a little sceptical about doing it myself and a little worried I'd struggle. But after removing the fog light cover the hose going into the turbo cooler was staring at me ��

Found it really easy to remove the old and replace with the new, going to take the car for a run down the motorway later, prob later tonight when it's quiet

Thank you guys for your guidance.

Good news, surprisingly easy isn't it?

I couldn't get my Ham fists through the fog light cover, so opted for the remove bumper technique. :beer:
