ProMAXX has released its Cylinder Head Repair Kit with new Blind ProSert.

This repair kit allows technicians to fix an incorrect repair where an attempt to drill out a broken exhaust manifold bolt has penetrated the cylinder head. 

“After fully extracting the damaged bolt, a technician uses a machine-shop-grade tooling tap to prepare the hole,” according to ProMAXX officials. “Then the Blind ProSert, with a light coat of liquid thread lock, is inserted into the hole, completing a repair that will remain leak free.”

The kit comes complete with a precision drill bit, tap, locking fluid, ProSerts and insert tool, all made in the United States of America.
