The principles of the coolant tube usage

Most often, the TOPRAN brand Coolant Tube that provides the coolant supply, fails, since it experiences the maximum loads, which is why the rubber dries up, and cracks and breaks appear on it. The malfunction is manifested by a coolant leak.

In this case, the defective coolant tube is replaced with a new one. For this, the antifreeze is drained, the clamps are removed. When removing an old part, it is important not to damage the brittle necks of the radiator. Next, a new coolant tube is attached, clamps are put on and tightened on it. At the end of the procedure, coolant is poured to the required level.

Make sure that the installed part is positioned correctly, not twisted, and the leakage of antifreeze is eliminated.
