Review on 🔝 Premium Quality TOPAZ Coolant Reservoir Expansion Tank with Sensor for BMW E60 E61 E63 E64 - Reliable Engine Cooling Solution by Kory Shelton

I installed this product earlier this week. It was incredibly easy, except I had to unhook the stuck bottom hose. My advice is to hold the bottom of the hose with your right hand and place it under the bottom of the tank with your left and try to pull the tank out of the hose. Don't forget to save the freeze plug from your previous tank (didn't know you needed to do this and I quickly ran out of antifreeze after a short ride) and make sure you lower the metal bracket on the top expansion hose all the way down as you like any liquid to lose.
