Peugeot 5008 1.6 HDi DV6 112 hp (2010): Replacing Coolant Hoses and Clamps

Hoses on the DV6 harden, crack and "sweat" at the clamp seats as they age. The job comes down to draining the coolant, replacing the damaged hoses with new clamps, refilling, and thoroughly bleeding the air out. Before disassembly, check the hose routing and the location of the retaining clips on your particular vehicle, and photograph the original layout.

Step by step

11 steps

Let the engine cool down completely. Open the hood, remove the engine cover and, if they are in the way of the hoses, the air duct and the air filter housing.
Park the vehicle on level ground, raise the front end if necessary and remove the engine undertray. Place the drain pan under the radiator.
Slowly unscrew the expansion tank cap (release the pressure first). Open the drain valve on the lower hose or radiator if there is one, or else remove the lower radiator hose and drain the coolant. Dispose of the drained fluid properly and do not leave it in an open container: it is toxic.
Photograph the position of all hoses, clamps and clips. Inspect each hose for cracks, bulges, soft or, conversely, rock-hard sections, and signs of leaks and white residue. Replace not only the leaking hoses but also any aged ones nearby.
Slide spring clamps along the hose with pliers. Release the quick-connect fittings (plastic clips) by pressing them with a screwdriver and pulling them out. Loosen worm-drive clamps with a screwdriver or socket. Do not force the hose off: if a hose is stuck, twist it on the fitting, then remove it.
Clean the fittings and seating surfaces of old rubber and residue. Do not use sharp tools, so you do not scratch the aluminum and plastic fittings: scratches cause leaks.
Install the new hoses, checking the direction of the bend and the position relative to neighboring parts. Lubricate the new O-rings on the quick-connect fittings with clean coolant. Use new clamps and clips and tighten them moderately; there is no specified torque for worm-drive clamps, and a snug fit without deforming the hose is enough.
Reinstall the air duct, air filter housing and engine undertray. Close the drain valve (if you opened it).
Pour coolant into the expansion tank up to the MAX mark. Leave the cap off.
Start the engine and hold the speed at about 2000-2500 rpm until the thermostat opens (the upper radiator hose becomes hot). Top up the coolant periodically. Set the heater to maximum to purge air from the heater circuit.
Shut off the engine, let it cool, check the level and close the tank. Take a test drive, and after the engine cools down, check the level again and inspect all connections for leaks.

Common mistakes and warnings

Never open the expansion tank cap on a hot engine: you can be burned by steam and hot coolant
Air pockets in the system cause overheating, so bleed the air out thoroughly and watch the coolant level and temperature gauge closely over the first few days
If you find signs of leaks on the hoses near the water pump or thermostat, check those components as well: they are replaced separately
