## Description

CT4074

Review: Essential for BMW waterpump replacement, and effective - I'm used to DIY on my cars so have loads of tools - but not this one. Picked it up in a rush after the waterpump on my '99 323i (E36) failed, and actually surprised at how good it is for the price, I was expecting something 'flimsy but with holes in the right places' and it's quite solid. It'd bend if you used it incorrectly, but done properly - perfect. The holes on the pulley holder are large enough to fit over the 10mm bolt heads - no silliness - just hold that bar straight or if you can, support it against something solid. My car's waterpump and fan are original items with 120,000 miles on, and the pump bearing collapsed spectacularly leaving a lot of free play on the pulley, but this held the assembly firm enough to undo the fan nut. Once used it's slim and easy enough to store away. For the price it's well worth it even as a one-shot tool. If you're considering DIY replacement of your BMW's waterpump, get this, and also consider replacing the viscous coupling if your car's fan is older. If your dealer/mechanic is going to charge a couple of hours labour to do this job, you can easily do it yourself (it's one of the easiest I've encountered) and for the same price, replace all the belts, the fan coupling and even tensioners. Without this tool you'll be swearing and trying to take radiators out and all sorts. With it, you could change a waterpump in 1/2 hour excluding the coolant drain/fill times; it also makes removing the fan and radiator shroud easy for better access to the alternator, A/C compressor and belts. One of the first things to buy after getting a six-cylinder BMW!
Review: Good quality item - Used to remove viscous fan from BMW. Perfect for the job and saved me a lot of money going to a garage. Heavy duty. Would recommend
