What does the Labwork Heater Control Valve replace?
▾
The Labwork Heater Control Valve replaces the original BMW heater valve that regulates hot coolant flow into the cabin heating core. When the factory valve fails, heat output drops or leaks appear. This aftermarket part fits the same mounting points and pressure rating, providing a direct drop-in replacement.
Does the valve require any special tools to install?
▾
Installation uses standard hand tools such as a socket set and screwdrivers. No special calibration equipment is needed because the valve is pre-filled and calibrated to OEM specifications. You will need to drain the cooling system and remove the old valve before fitting the new one.
How long can I expect the valve to last?
▾
With proper installation and regular coolant maintenance, the stainless-steel Labwork valve typically lasts the lifetime of the vehicle, often exceeding 100,000 miles. Its high-temperature seal and corrosion-resistant construction help prevent premature leaks that are common in cheaper plastic replacements for many owners.
Is this valve compatible with all BMW E36 models?
▾
The valve is designed for the E36 platform covering 318i, 323i, 325i, 328i and M3 models produced between 1992 and 1999. It matches the OEM part number 64118375792, so any vehicle that originally used that number will accept the Labwork replacement.
Can I use this valve with a different coolant type?
▾
The valve itself is coolant-agnostic, but BMW recommends using a phosphate-free ethylene-glycol coolant that meets the manufacturer’s specifications. As long as the coolant meets BMW’s standards, the Labwork heater valve will function correctly without corrosion or sealing issues for the vehicle.
