## Abstract

An oil/coolant module for a combustion engine, includes an oil filter, an oil/water heat exchanger, a water pump, and a coolant treatment system comprising a water filter and containing treatment additives for a coolant circuit.

## Claims

### Claim 1

An oil/coolant module for a combustion engine, comprising:
a housing adapted to be connected to an engine block;
an oil/water heat exchanger arranged in the housing;
an oil filter arranged on the housing;
a water pump housing; and
a coolant treatment system comprising a water filter,
wherein oil passes from said heat exchanger to the oil filter,
wherein one portion of coolant passes to the coolant treatment system and another portion flows out of an outlet to cool the combustion engine,
wherein the oil/coolant module is a self-contained unit connectable to the combustion engine, and
wherein said one portion of the coolant passes to the coolant treatment system after passing said heat exchanger.

### Claim 2

An oil/coolant module for a combustion engine, comprising:
a housing having a connection surface adapted to be connected to an engine block;
an oil/water heat exchanger arranged in the housing;
an oil filter arranged on the housing;
a water pump housing having an outlet in fluid communication with a space containing said heat exchanger; and
a coolant treatment system comprising a water filter,
wherein oil passes from said heat exchanger to the oil filter,
wherein the oil/coolant module is a self-contained unit connectable to the combustion engine via the connection surface, and
wherein one portion of coolant passes to the coolant treatment system and another portion flows out of an outlet to cool the combustion engine and wherein said one portion of the coolant passes to the coolant treatment system after passing said heat exchanger.
