On models with a 4-cylinder engine, the pump is located in the direction of travel in front to the left of the engine and is driven by a V-belt
Warning: Do not ride without this belt.
On models with a 5-cylinder engine, the pump is also located in front on the left, but it is driven by a toothed belt.
The pump of the 6-cylinder engine is driven by the outer side surface of the toothed belt.
During the entire service life, the water pump does not require maintenance. If it becomes leaky or makes a whistling sound, it should simply be replaced as it is beyond repair.
For a 6-cylinder engine, the thermostat housing (arrow) located forward to the right of the cylinder block.
The figure shows the position of the thermostat on models with a 6-cylinder engine. Air valve (arrow) should point up.
Models with a 6-cylinder engine have a water pump (arrow) located in front of the cylinder block. It is driven by the outer side surface of the toothed belt.
Removing the water pump
You will need either a new gasket (4- and 6-cylinder engines) or a new o-ring (5 cylinder engine). Owner of a 4-cylinder vehicle who buys a new water pump receives a complete pump and housing (rear housing with pump). 5-cylinder pumps can be identified by the stamped number 5 in the area of the flange gasket - must be equipped with an O-ring with an oversize diameter of 5 mm.
When working with a 4-cylinder engine, first remove the V-belt.
Remove toothed belt guard (chapter «Engines»).
Loosen a total of seven screws between the front bearing housing and the water pump housing. The pump wheel is located in the bearing housing.
Replace gasket between bearing housing and water pump housing.
When the whole water pump housing is removed (spare part application), when installing, the seal between the housing and the cylinder block must also be replaced.
Tighten bearing housing to 10 Nm, tighten V-belt pulley clamping bolts to 25 Nm.
Removing the water pump when working with a 5-cylinder engine is not an easy job:
First you need to remove the power steering pump along with the V-belt.
Remove toothed belt guard (chapter «Engines»).
Loosen the toothed belt and remove it from the water pump gear.
Unscrew the clamping bolts of the water pump, remove the pump.
Install a new pump with a new O-ring.
Tighten water pump clamping bolts to 20 Nm.
Put on a toothed belt, be sure to check the valve timing (chapter «Engines and their inner life»).
Pull on toothed belt.
The rest of the assembly goes without problems.
When working with a 6-cylinder engine, the removal of the water pump on its own again rests on the removal of the toothed belt.
Remove V-ribbed belt (chapter «Generator»).
Remove toothed belt (chapter «Engines»).
Loosen the nine bolts on the front of the water pump housing, remove the housing.
Left: water pump (1) The 4-cylinder engine is located on the left front on the engine. Position (2) shows the thermostat housing cover, the arrows point to some of the water pump bearing cover mounting bolts.
Right: water pump (arrow) The 5-cylinder engine is located on the engine in front and is driven by a toothed belt.
When installing, replace the gasket, tighten the bolts in two passes, the last with a torque of 10 Nm.
Put on a toothed belt, be sure to check the valve timing (chapter «Engines»).
