A very common point of coolant seepage on your Duramax is at the factory coolant block off plate located towards the rear of the engine on the passenger side. Over time, the gasket becomes brittle and will allow coolant to sneak by. This direct replacement block off plate features an integrated o-ring that is a simple to install upgrade to ensure a leak free engine.IMPORTANT NOTES:
- Sold individually
- Reuses factory mounting bolts
- GRP's product line was originally intended for installation shops and to be purchased in bulk quantity, which in turn means that there are no installation instructions that come with any of their products. We feel that this compromise is easily countered with the exceptional craftsmanship that goes into these kits, as well as the price point. If you are unsure of how to install any of their components, but still want to tackle the job yourself, there are plenty of generic installation videos available online that will allow you to still take advantage of the benefits of purchasing GRP.
