Abstract
A repair kit and associated method for repairing an automotive coolant pipe for fluid-conducting within an engine block of an engine includes at least a repair stent, sealant and instructions for performing the method. The repair stent may be a whole tube, or a hollow semi-cylinder defining a gap. The method includes draining coolant from the engine, removing the water pump from the engine without removing the timing chain cover of the engine, inserting the repair stent including a sealant through the coolant passage, wherein the coolant passage extends through the timing chain cover into the engine, re-assembling the water pump to the engine and adding coolant to the engine.
