The thermostat is OEM quality and was very easy to install. Take some time to look the the DIY videos before you start the job. I chose to get a kit from FCP Euro. I did this ecuase the price was amazing and it made sense to replace parts that were old and would be,removed during this project. All the parts I received were OEM quality and fit exact. The gasket comes with the unit.

Perfect fit for my e46 2003 325i. OEM quality. My thermostat error code disappeared when I swapped this in!

The price was right and being OEM the fit was perfect. Extra piece of mind with the new Meyle water pump. Shipping was prompt as always with FCP.

Change around 50

At 1st I was upset. I open the box and found it plastic like the one I was removing from 2001 325xi with 136,000 miles. I bought car with 90k a few years ago. Then when I removed the water pump I found the propellers where metal like the Hepu 11517527910H. Hmm am I doing this all for not. Or should I just have replaced the leaky expansion tank and had been done. Then I wiggled the old water pump and noticed the bearings starting to let the shaft wiggle. So it looks like the pump was going. So it looks like these after market water pumps don't last to long. So my point is when I replace the water pump again at 200k I will definitely change out the thermostat assembly at the same time; even if it was aluminum I would still replace it then. So why blow an extra $40 more on an aluminum housing. Get this plastic one and buy a better pump with the savings and replace both again in 60k miles. This thermostat looks solid and bolts right in. Looks identical to one I took out and electrical wiring prongs fit nice and tight. Note u will need two of the thermostat bolts to loosed the water pump assembly. So take off the water pump before putting ther back on car. The water pump comes out by removing four nuts then by screwing in two bolts and it comes out. Like screwing in a bolt on the disc rotor to make it come off. All the bolts and nuts get 89 "in"-pounds and the one big bolt gets 17 "foot" lbs.

Direct replacement to original. Includes the gasket so don't order extra.
