If flow is blocked in these ports, you will cause a pressure differential on your water pump impeller creating cavitation, resulting in aeration of your coolant and an overheating condition.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cspan\u003eThis product is intended to solve this issue, while also adding a convenient place to mount your stock gauge coolant temp sensor, as well as an aftermarket CTS if desired.
