Diagram ref no 19

The control and regulating unit directs or regulates coolant flow to the oil cooler, helping the engine oil reach and maintain the correct operating temperature. By controlling oil cooler performance, it supports stable lubrication, engine efficiency, and long-term protection of internal engine components.

Functions
•  Regulates coolant flow through the engine oil cooler circuit
•  Helps control engine oil temperature
•  Supports stable engine lubrication performance
•  Helps prevent excessive oil temperature during operation
•  Assists efficient engine warm-up and cooling control
•  Supports overall cooling system and thermal management function
•  OE Match replacement for a worn, leaking, or faulty original unit

Why Replace This Part?
The oil cooler control and regulating unit is exposed to constant heat cycles, coolant pressure, vibration, and age-related wear. Over time, internal regulating components or seals can fail, leading to coolant leaks, poor oil temperature control, overheating concerns, or cooling system faults. Replacing a faulty unit helps restore correct oil cooler regulation and protects the engine from temperature-related wear.

When to replace
•  Coolant is leaking from the oil cooler regulating unit area
•  Oil temperature is running higher than normal
•  The engine shows overheating or cooling system warning messages
•  The unit is cracked, damaged, blocked, or leaking
•  Coolant residue or staining is visible around the component
•  The oil cooler, thermostat, or related coolant pipework is being serviced
•  Diagnostic checks indicate a cooling or temperature regulation fault
•  As preventative replacement during major cooling system repair

Where it fits on the car
This unit fits in the engine cooling and oil cooler circuit. It is positioned around the oil cooler / coolant regulation area, where it controls coolant flow to support engine oil temperature management. Exact location may vary depending on model and engine layout.
