Cooling system components - re‐

move and install

Note

♦

The cooling system is under pressure when the engine is hot.

Thus, it is necessary to reduce the pressure before doing re‐

pairs.

♦

Hose junctions are fastened by spring clamps. When doing

repairs, use spring clamps only.

♦

To install spring clamps, we recommend using Standart-type

clamp pliers -VAS 5024A - or Hose clip pliers -VAG 1921- .

Check the cooling system tightness with the Engine cooling sys‐

tem tester -VAG 1274- and the Adapter for VAG 1274 -VAG

1274/8- and the Adapter for VAG 1274 -VAG 1274/9- .
