When it comes to BMW's we all know the weak point is commonly in the cooling system, many models proving hard to bleed the air pockets out after the refresh. The coolant refill tool solves this problem, ensuring that you get an air pocket free fill. The entire task is as simple as draining the system like normal, reinstalling the drain plugs and hooking the tool up to your refill location. The reason this tool works so well is due to the venturi valve, it converts air pressure from the compressor to vacuum inside the cooling system, then with a twist of a valve sucks coolant right into the system using the vacuum pressure.

Replacing the fan clutch on most BMW models requires holding the water pump pulley while removing the fan clutch lock nut. With less than 1 1/2" clearance on some models this project can easily turn into a mechanical nightmare. Using our special slim line fan clutch wrench in conjunction with the appropriate pulley spanner, the removal and installation required only a few moments.

This expansion tank cap, from the E30 325is, is designed to give way at 20 PSI instead of 30 PSI, like the stock cap. In the event the system over-pressurizes, this cap should let go first, potentially saving your radiator, hoses, or other vital cooling system components. While there's no guarantee it will save your radiator, this small part could mean the difference between calling a tow service and making it home, and a little extra insurance never hurt. This cap is a high-quality aftermarket part from an OE supplier.

The coolant expansion tank cap keeps necessary pressure on your coolant to increase efficiency. If you have an overheating issue in your vehicle, a simple, quick, and inexpensive part to replace is this cap.
