(3-00541) Genuine BMW M42/M44 Engine Block Coolant Fitting (11531714738)
Genuine BMW replacement coolant fitting located on the side of the engine block on all M42 and M44 4 cylinder engines.
Replacing this fitting is just as important as replacing the
water pump, thermostat or radiator. The failure of this often
overlooked coolant fitting has caused blown head gaskets and even
completely blown engines. We suggest replacing this fitting every 90,000
miles. Do not wait till the fitting fails to replace it, this is one
you want to stay in front of.
The Genuine BMW fitting is the best on the market. The less expensive aftermarket fittings do not match the quality fit and function of the OE part. As a result, BimmerBum only sells the Genuine BMW (OE) version of this part.
Sealing o-ring is included.

Note: For all M44 engines we strongly recommend the simultaneous replacement of a similar fitting on the back of the cylinder head, BMW part number 11 53 1 743 679.
