Stripped BMW Radiator Expansion Tank Bleeder Screw

What to do when your expansion tank bleeder screw strips out? If you're like most of our frustrated customers, you've probably noticed a leak developing in your radiator at the expansion tank where the bleeder screw is located. See the picture below for an extreme example of what can happen when this problem gets worse.

This is because the stock bleeder screw is plastic and it is very easy for this screw to strip out. Either the screw itself will get crossed threaded or the internal threads of the expansion tank become damaged. Either way, coolant can start to leak which can leave you stranded on the side of the road with an overheated beamer! 

Fortunately there is a simple fix for this issue! FGT Motorsport has developed and manufactured a solid billet brass bleeder screw that is a permanent solution for the stripped out bleeder screws in your BMW! With this screw, you will never need to buy another bleeder again for your expansion tank! Many of our customers also have to replace the expansion tank when the internal threads strip out and we HIGHLY recommend picking up our brass bleeder with the new tank or your existing tank to prevent stripping from ever happening again.
