Danger! | Risk of injury to skin and eyes caused by scalding from contact with hot coolant spray. Risk of poisoning from swallowing coolant. | Do not open cooling system unless coolant temperature is below 90°C. Open cap slowly and release the pressure. Do not pour coolant into beverage containers. Wear protective gloves, protective clothing and safety glasses. | |
1 | Switch on ignition | ||
2 | Adjust heater to maximum heat output | ||
3 | Unscrew cap (1) on expansion reservoir (2) | Slowly unscrew cap and reduce the excess pressure. | |
4 | Check coolant level and antifreeze content of coolant. | If the antifreeze content of the coolant is too low, either antifreeze must be added or the coolant must be replaced. | |
Drain coolant, fill. | |||
5 | Screw test cap (3) onto expansion reservoir (2) | | |
6 | Connect pressure pump (4) at test cap (3) | | |
7 | Apply test pressure to cooling system | To prevent damage to the cooling system, do not exceed the stated test pressure | |
| Checking | ||
8 | Inspect condition and installation at hose clamps; retighten or replace if necessary | 6 mm socket hexagon on flexible shaft for hose clamps with worm drive | |
