If you're dealing with coolant issues on your BMW, this EVIL ENERGY reservoir tank is a solid replacement option that won't break the bank. I installed this on my 2004 BMW X5 that had a cracked reservoir, and the fit was perfect - just like the original factory part. The tank comes with a cap included, which is nice because sometimes you need to replace both. The 30 PSI pressure rating matches the OEM specifications, so you don't have to worry about compatibility issues. Installation was pretty straightforward - just drain your coolant, swap the tanks, refill, and bleed the system. The quality of the plastic seems good and durable, able to handle the engine heat and vibration without issues. It's been in my X5 for about four months now through some pretty extreme temperature changes, and no leaks or problems whatsoever. The tank has clear min/max markings that make checking your coolant level easy. EVIL ENERGY includes a 1-year warranty, which gives me confidence in the product's longevity. This fits a ton of BMW models from 1999-2010 including various 3-series, X3, and X5 models. If you're experiencing coolant loss or see cracks in your current reservoir, this is definitely worth considering before the problem leaves you stranded. Much more affordable than going to the dealership, and the quality seems comparable to OEM. Just make sure to use the proper BMW coolant when refilling your system!
