Hey there, if you're dealing with cooling system issues, this VEMO temperature switch might be exactly what you need! This is a 3-pole switch that activates your radiator fan at specific temperatures to keep your engine from overheating. It kicks in at 105°C and 95°C on the high side, then switches off at 100°C and 90°C - pretty smart system that prevents constant cycling. The M22x1 thread size makes installation straightforward, and you'll need a 29mm spanner to get it properly tightened. Comes with a seal included so you don't have to worry about coolant leaks after installation. Perfect replacement for when your old switch stops working properly and your engine starts running hotter than it should. Much better than dealing with overheating issues that can lead to serious engine damage down the road. The build quality feels solid and reliable, just like you'd expect from VEMO parts. Installation is pretty straightforward if you're comfortable working around your cooling system - just make sure the engine is cool before you start! Works exactly as specified and helps maintain that perfect operating temperature range your engine loves. No more guessing whether your fan will kick on when it needs to. Definitely one of those parts that seems small but plays a huge role in keeping your vehicle running smoothly. Whether you're a DIY mechanic or a professional, this switch delivers reliable performance that'll keep your cooling system working like it should.
