ProMAXX Tool expanded their line of exhaust manifold repair tools with the introduction of the Elizabeth II ProKit, capable of removing hardened titanium bolts commonly found in the Ford 3.5L EcoBoost.
Unlike other Ford engines, the 3.5L EcoBoost is equipped with titanium alloy exhaust manifold mounting studs. In stock form, the titanium mounting studs tested to a Rockwell "C" table hardness of 29-32. However, under extreme heat from the turbo chargers and samples pulled from a recent ProMAXX assisted repair, they have found the stud's hardness under these conditions actually increased to over 50, according to the company.
The kit combines ProMAXX Tool’s precision engineered guide plates (commonly called drill templates or jigs) with high-grade platinum tooling that is capable of drilling through the hardened metal in broken bolts. This Elizabeth II ProKit is designed to allow technicians facing broken manifold bolts on Ford EcoBoost engines to make the repair necessary.
