Oil thermostat

This oil thermostat is a greatly improved replacement for the original thermostat. It simply replaces the original and the stock oil lines and banjo bolts are re-used. The thermostat has a built in safety bypass that guarantees some oil flow and this also eliminates the need for bleeding the thermostat. (you always do that we hope) Another feature is that the physical size and shape of this part makes it much easier to remove and install than the original part.

As the engine oil temperature rises, the flow to the oil cooler increases and the bypass flow is gradually reduced. This begins to occur at 90° C (~190° F) and at 96° (~200° F) the valve opens fully and all oil flows through the cooler. The thermostat ensures that the engine safely reaches normal operating temperature faster, reducing wear.

Precision machined of high quality aluminum billet and all bores are finely honed. Made in Germany
