4.1 PRESSURE TESTING
}
When the coolant is hot, there is
overpressure in the cooling system.
Carefully remove the filler cap to
release the overpressure. Coolant is
a toxic fluid. Contact with the skin
should therefore be avoided. To
avoid damaging the cylinder block;
do not top up a warm engine with
cold coolant.
If this is done when the engine is
warm, any cracks can be spotted
more quickly.
The cooling system can be checked
for leaks with a pressure-test pump.
1.
Open the grille.
2.
Remove the filler cap.
3.
Fill the cooling system to the correct level.
4.
Raise the engine temperature. This need not
be the operating temperature.
5.
Fit a pressure-test pump. Pressure-test the
system at the specified pressure. See
"Technical data".
6.
Check for leakage.
