CAUTION: The heater inlet and outlet fittings use O-ring seals which form a leak-proof
hydraulic seal if tightened properly. To prevent damage to the seals, do not over-tighten
fittings.

2.08 kg (15 ft-lb).
2. Install the fluid outlet fitting to the fluid outlet port. Tighten the fluid outlet fitting to
