Check Engine Coolant Level, Clean Radiator And Oil Cooler - Volvo DD29 Operator's Manual

SECTION 5

Check Engine Coolant Level, Clean Radiator and Oil Cooler

Injury can occur when removing the radiator cap.
Steam or fluid escaping from the radiator can burn. Inhibitor contains
alkali, avoid contact with skin and eyes. May cause serious injury or
death.
Always shut down the engine and allow it to cool down before removing
the radiator cap. Remove cap slowly to relieve pressure. Avoid contact
with steam or escaping fluid.
1. Check engine coolant level by observing the level in the coolant recovery bottle
(1, Figure 5-13). Coolant level should be at the "CPLD FILL MIN" mark. If
required, add a 50-50 mixture of coolant and water to bring coolant to the
proper level.
Coolant Level must be maintained. Air will enter engine coolant system if
no coolant is present in the bottle.
2. Check for signs of clogging of exposed cooling fins on the radiator
(1, Figure 5-14) and oil cooler (2).
3. If clogging is dried on dirt, use a suitable brush to remove from cooling fins. If
dry dust is present, use compressed air to clean.
When using compressed air, water jets or steam cleaning methods,
ensure that appropriate protective clothing is worn to protect eyes and
exposed parts of the body.
4. In case of severe clogging due to fluid leaks, apply diesel fuel or a commercial
cleaning detergent; let it soak in, and then wash off with a water jet.
