Checking The Coolant System For Tightness - Skoda FABIA 2000 Workshop Manual

FABIA 2000 1.0/37; 1.4/44; 1.4/50 Engine, Mechanical Components
Checking the coolant system for tight-
ness
Special tools, test and measuring equipment and
auxiliary items required
♦
Coolant system tester (e. g. -V.A.G 1274-)
♦ Adapter (e.g. -V.A.G 1274/8-)
♦ Adapter (e.g. -V.A.G 1274/9-)
Test condition
•
Engine must be warm
Test sequence
Caution!
Hot steam may escape when the expansion reser-
voir is opened. Cover the cap with a cloth and
open carefully.
–
Open the cap of the coolant expansion reservoir.
–
Position coolant system tester (e. g. -V.A.G 1274-)
with adapter (e. g. - V.A.G 1274/8-) on the coolant ex-
pansion bottle.
–
With the hand pump of the tester generate an over-
pressure of approx. 0.1 MPa.
–
If the pressure drops determine location of the leaks
and repair them.
Testing the pressure relief valve in the cap
–
Screw cap onto tester with adapter (e.g. -V.A.G 1274/
9-).
–
With the hand pump of the tester generate an over-
pressure of approx. 0.15 MPa.
–
The pressure relief valve must open for an overpres-
sure of 0.12 to 0.15 MPa.
