Intercooler, pressure testing

Intercooler removed

Special tools: 3849613, 885533, 885538

1. Install plugs 885533 and 885538 on the intercooler’s sea water unions on the covers (1).

Connect pressure test equipment 885531 to plug 885533.

Pump the pressure up to 150 kPa. Leave the equipment under pressure to ensure that the intercooler and its O-rings seal correctly.

IMPORTANT! If the pressure falls, the intercooler connection must be checked with leak testing compound (such as soapy water) to determine where the leakage comes from.

2. If the pressure falls, although you have determined that the connections are tight, the intercooler must be changed.
