Condensation can form in the charge air cooler during
operation. The condensation is drained from a nipple
on the bottom of the charge air cooler. Make sure the
nipple is not blocked.
IMPORTANT ! If considerable amounts of water
run out of the drain hole, the insert must be re-
moved and test pressurised. This must be done
by an authorised workshop.
