Maintenance work
The easiest way to identify leaks in the cooling system is when the engine is warm and, therefore, the cooling system is dominated by operating pressure. Then wear work gloves to check the water hoses to avoid burns.
Are the hoses on the radiator and on the engine sealed, as well as the thinner hoses to the heating system and to the throttle body?
Cracks in the hoses? Knead them to see if the hoses have become stiff and brittle - in this case, replace.
By kneading the hoses, you will also find leaks caused by rodent bites
Are the ends of the hoses loosely attached to their fittings?
Do the hose clamps fit perfectly?
Are the hose clamp tension bolts tight where they are?
Rusted hose clamps may unexpectedly fail to withstand the load while driving and at full operating pressure in the cooling system. Therefore, urgently replace them!
In the workshop, the tightness of the cooling system is checked with a special manual air pump with a pressure gauge.
This device is installed in the opening of the expansion tank and pumps up a pressure of 1 bar.
If the arrow on the scale does not deviate within one or two minutes, then the system is tight.
Left: The coolant hose clamps can be easily released with the water pump wrench.
On right:Radiator removal. Unscrew the right and left retaining earrings of the radiator from the front metal part. Remove the radiator together with the fan upwards from the engine compartment.
