Its purpose is to allow a tiny amount of coolant to escape if the internal shaft seals are starting to fail. If you notice a steady drip, crusty green\/red coolant stains, or puddles of antifreeze directly beneath the pump, the internal seal is compromised, and the pump must be replaced.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"5\"\u003e2. Engine Overheating or Fluctuating Temperatures\u003c\/b\u003e\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\"\u003eIf the pump's internal impeller is slipping on the shaft, has eroded due to cavitation, or if the drive belt is slipping, the coolant flow rate drops drastically. You will notice the temperature gauge on your dash creeping into the hot zone, especially when pulling heavy loads or climbing steep grades.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"7\"\u003e3. Grinding, Growling, or Squealing Noises\u003c\/b\u003e\u003c\/p\u003e\n\u003cp data-path-to-node=\"8\"\u003eIf the internal bearings supporting the pump shaft dry out, wear down, or fail, they will emit a distinct mechanical noise. This can range from a high-pitched squeal under belt tension to a low, rough grinding or growling sound coming from the front of the E7 engine at idle.\u003c\/p\u003e\n\u003cp data-path-to-node=\"9\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"9\"\u003e4. Visible Play or Wobble in the Pump Pulley\u003c\/b\u003e\u003c\/p\u003e\n\u003cp data-path-to-node=\"10\"\u003eWith the engine safely turned off, grab the water pump pulley (or the fan clutch assembly if attached nearby) and try to wiggle it. If there is any noticeable physical play, looseness, or wobble, the heavy-duty bearings are completely shot. This is a critical warning; a wobbling shaft can suddenly snap or shred the drive belts, causing instant loss of cooling.\u003c\/p\u003e\n\u003cp data-path-to-node=\"11\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"11\"\u003e5. Low Coolant Levels and Sweet Antifreeze Odor\u003c\/b\u003e\u003c\/p\u003e\n\u003cp data-path-to-node=\"12\"\u003eA slow, continuous leak from the water pump's mounting gasket or rear seal will gradually lower your coolant level. You may smell a distinct, sweet maple-syrup-like aroma of hot antifreeze while driving or immediately after parking your truck, even if you can't spot the exact puddle right away.\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003e\u003c\/strong\u003e \u003cstrong\u003eManufacturer information\u003c\/strong\u003e\u003cbr\u003eMack trucks are built to last, but when the time for repair and maintenance comes it’s strongly recommended to use genuine \u003cstrong\u003eMack®\u003c\/strong\u003e components.
