Fig. 5.59. Water pump of the Duratec Ti-VCT engine with a volume of 1.6 l: A – tension roller of the timing belt; B - water pump; B – bolts for fastening the water pump to the engine cylinder block.
Remove the pump for repair or replacement if noise occurs during its operation, the level of which exceeds the normal level and which occurs when a large radial play of the pump shaft is formed, as well as when coolant leaks from the pump shaft seal.
Disassembling the pump is quite labor-intensive, so if it malfunctions, we recommend replacing the pump as a whole.
For replacing the water pump of the Duratec Ti-VCT 1.6L engine perform the following operations.
You will need: an 8mm socket, a flat-blade screwdriver, and all the tools needed to remove the accessory drive belt (see Checking and replacing the accessory drive belt) and the timing belt (see Checking and replacing the timing belt of the 1.6L Duratec Ti-VCT engine).
1. Drain the engine cooling system (see Replacing the coolant).
2. Remove the accessory drive belt (see Checking and replacing the accessory drive belt).
3. Remove the timing belt (see Checking and replacing the timing belt of the 1.6L Duratec Ti-VCT engine).
WARNING: After removing the timing belt, do not turn the crankshaft or camshafts, as the pistons may damage the valves.
NOTE: It is only necessary to remove the timing belt on vehicles manufactured since April 2005, as these vehicles have a belt tensioner roller mounted on the water pump housing. On vehicles manufactured before April 2005, the tensioner roller is mounted on the engine block and it is not necessary to remove the belt when replacing the water pump.
4. Unscrew the six bolts B (Fig. 5.59) securing the water pump B to the engine cylinder block, use a screwdriver to pry up the water pump housing and remove the pump together with the tension roller A of the timing belt.
NOTE: The timing belt tension roller is secured to the water pump housing with bolt B.
5. Remove the gasket installed between the water pump housing and the engine cylinder block.
CAUTION: Always replace the water pump housing gasket with a new one whenever it is removed, regardless of its condition.
6. If the new water pump does not have a timing belt tension roller, remove bolt B securing the roller to the pump body and install the roller on the new pump. Tighten the roller mounting bolt to 28 N·m (2.8 kgf·m).
7. Install the water pump in the reverse order of removal. Tighten the pump mounting bolts evenly crosswise to a torque of 10 N·m (1 kgf cm).
HELPFUL TIP: Apply a thin layer of sealant to the water pump housing gasket on both sides.
8. Install the timing belt and adjust its tension (see Checking and replacing the timing belt of the 1.6L Duratec Ti-VCT engine).
9. Install the remaining parts in the reverse order of removal.
WARNING: Replace the accessory drive belt with a new one, as it cannot be reused once removed.
10. Fill the coolant and remove air locks from the cooling system (see Replacing the coolant).
For replacement of water pump of Duratec-HE engine with capacity of 2.0/2.3 l perform the following operations.
You will need: an 8mm socket, a flat-blade screwdriver, and all the tools needed to remove the accessory drive belt (see Checking and replacing the accessory drive belt) and the timing chain drive (see Replacing the timing chain of the 2.0 and 2.3 L Duratec-HE engines).
1. Drain the fluid from the engine cooling system (see Replacing the coolant).
2. Remove the accessory drive belt (see Checking and replacing the accessory drive belt).
3. Remove the three water pump pulley mounting bolts…
4….and remove the pulley.
5. Remove the water pump mounting bolts…
6….and remove the pump.
7. Remove the gasket installed between the water pump housing and the engine cylinder block.
CAUTION: Always replace the water pump housing gasket with a new one whenever it is removed, regardless of its condition.
8. Install the water pump in the reverse order of removal. Tighten the pump mounting bolts evenly in a crisscross pattern to a torque of 10 N·m (1.0 kgf·m).
HELPFUL TIP: Apply a thin layer of sealant to the water pump housing gasket on both sides.
9. Install the remaining parts in the reverse order of removal.
WARNING: Replace the accessory and air conditioning compressor drive belts with new ones, as they cannot be reused once removed.
10. Fill the coolant and remove air locks from the cooling system (see Replacing the coolant).
