How Many Under-tightened Diesel Intake Clamps

On the intake of the Diesel, there are 5 hose clamps holding together the various pieces between the air filter and the entrance to the turbo. These are the type that use a flat head screw to tighten them around the tube. When I checked mine tonight while changing my air filters, I discovered that 3 of the 5 were under-tightened--two of them so loose I could turn the screws by hand without a screwdriver. As un-metered air entering the intake has been proposed as a contributing factor to the sensor failures that some of us have experienced, this is something we should all probably check, along with visually inspecting for areas that could be drawing air. I would like as many Diesel owners as possible to check their hose clamps and report in the poll above how many were under-tightened. If you had any under-tightened clamps, post the age and mileage of your vehicle below. (2 years, 46,000 miles for me.

Thats why my girlfriend drives my jeep zj. every single thing that can take a fluid is color coated so that it follows the legend on the radiator frame. red cap on the stick is ATF, green cap is rad overflow, yellow is motor oil and so forth. they literally wife proofed the jeep.... yah never mind

I just take a black sharpie and mark everything. Battery, radiator, radiator overflow, windshield washer fluid , oil, brake fluid etc. my dad taught me all about cars, but I don't expect my kids to know unless I teach them. Most people just want to put gas/diesel In their Cruze and just go........

2015 with 500 miles, all 5 loose, 2 of them closer to intake side on left ( not engine) took three full rotations with flat head screwdriver to tighten. Great thread and thanks for the help. Color me shocked that GM would not issue a TSB to have these checked every time upon service and/or sale of vehicle.

Is there a thread for 1.4L engine hose clamp tightness? I haven't checked but I will next time I get under the hood.

This is for us diesel guys, but no reason you can't start a thread. It's an issue with us because of a sensor. I'd grab a flat head screwdriver and check yours anyway, nothing to lose. Just don't over tighten the hose clamps.
