Volvo Red Block Freeze Plug Retainers - Blank, Stainless Steel
Set of 8 Blank, Stainless Steel freeze plug retainers for red block Volvo's.
High performing red blocks often push out freeze plugs for various reasons, and freeze plug retainers are a solid solution to this problem.
I highly recommend using the cup-style freeze plug over the disc type with this style of retainer, installing the freeze plug flush to the block so the retainer is in contact with the "rim" of the freeze plug.
These are manufactured from laser cut 1/8" 304 Stainless Steel, deburred, surface finished and packaged in sets of 8.
I've not included fasteners or installation tools(drill, taps, ect) as most engine builders already have the required tools and have strong preferences in fastener style/size. However, I recommend M4 x 8mm fasteners.
Block drilling, tapping and clearancing is required for installation!
