Usually, a liquid leak from a hose occurs while driving and emergency measures have to be taken. So-called repair kits are offered at filling stations. We are talking about adhesive tape that can be used to seal off a leak in a hose after thoroughly cleaning it. If the crack in the hose is large enough. It is recommended to loosen the cap on the expansion tank by one turn to reduce the pressure in the system. Using the repair kit and constantly monitoring the coolant level in the system and its temperature, you can drive to the nearest workshop.
1. Drain the coolant from the system.
2. Loosen the clamp on the hose by unscrewing the clamping screw with a screwdriver. If the hose is secured with a clamp, release the ends of the clamp.
3. Remove the hose from the branch pipe. If it fits tightly, you can loosen the fit by inserting a screwdriver between the pipe and the hose.
4. Place the new hose on the branch pipe and secure it with a clamp. When securing the hose with a clamp, do not exceed the tightening torque of the screw. You can strip the threads or even cut the hose with a clamp.
Cooling system hoses can also be secured using so-called quick-release fasteners, without the use of clamps. There are two types of such hose fastenings and they are designated by the name of the manufacturing company: a hose with a Conrad fastening and a hose with an Ofelie fastening (see illustrations 9.0 and 9.0a).
9.0 Hose with Conrad mount.
1 - bracket
2 - sealing ring
3 - hose
A - slots for brackets
B - groove for sealing ring
9.0a Hose with Ofelie mount.
1 - bracket
2 - sealing ring
3 - hose
A - slots for brackets
B - groove for sealing ring
To disconnect the hose with the Conrad mount, remove the I clamp.
5. Check the condition of the sealing ring. When connecting the hose, the clamp I must be inserted into the splines A, and the sealing ring must also be installed in the groove B (if necessary, replace the ring with a new one).
6. Slide the hose onto the fitting. To ensure the hose is securely fastened, pull it towards you. To disconnect the hose with the Ofelie mount, remove the clamp 1 using pliers for thrust rings and at the same time remove the hose 3.
7. Remove sealing ring 2 from groove B. When connecting the hose, insert clamp 1 into splines A. If necessary, replace the sealing ring with a new one and put the hose on the connecting pipe so that it fits onto the guide protrusions.
8. Feed the hose onto the fitting until the clamp snaps into place. To ensure the hose is securely fastened, pull it towards you.
