Adding Coolant After System Drain - MacDon M2170NT Operator's Manual

6. Locate radiator drain valve (B) on radiator inlet tube (A). It
is located inside the frame beside the engine.

under the drain valve, and then open radiator drain
valve (B).
8. When the system has been completely drained, close
radiator drain valve (B).
9. Add coolant after a system drain. For instructions, refer to
Adding Coolant after System Drain, page
10. Close the hood. For instructions, refer to

Adding Coolant after System Drain

Coolant is cycled through the engine to help reduce internal heat. The coolant tank should be at least one-half full; if it is
less, add coolant.
CAUTION
To avoid personal injury from hot coolant, do NOT attempt to open the pressurized coolant tank cap until the
engine cools.
1. Open the hood. For instructions, refer to
Hood, page 287.
2. Remove pressurized cap (A) from the coolant recovery tank.
IMPORTANT:
Use nitrite free coolant only. For coolant specifications,
refer to 6.1.2 Lubricants, Fluids, and System Capacities,
page 279.
3. Add coolant at a rate not exceeding 11 L/min (3 gpm) until
the recovery tank is one-half full.
NOTE:
When adding coolant, use MAX COLD line (B) on the side of
tank that faces the cab for an accurate measurement.
DANGER
Ensure that all bystanders have cleared the area.
4. With the pressurized cap off, start the engine and run it at high idle for approximately 20 minutes or until the engine
temperature reaches 85°C (185°F).
5. Add coolant until the recovery tank is one-half full. Check the coolant level again. For instructions, refer to
Checking Engine Coolant, page
6. Reinstall pressurized cap (A).
