intake elbow keeps busting on engine at least once a year sometimes more. This needs to be recalled and made into a metal part or something that can withstand the constant heat and cooling depending on the temperatures outside.

water was leaking out of a "weeping" hole on the water pump. This part was not very expensive. The part was equally not that difficult to replace, 9 bolts- and time. local santee shop quotes $365 for parts and labor. my friend, the right tools, and anafternoon. good times......good luck

Just discovered water pump leaking and very loose, causing a loud squealing and grinding sound. Attempting to fix myself, but with having to buy jack stands and flush the coolant as well is extremely inconvenient, as I am in a major time crunch to fix it in less than 12 hours and I didn't detect signs of the problem before the loud squealing/grinding that started today. If the belt slips, the engine could seize and I can't take the risk. Is there a recall for this??

Radiator fan runs almost constantly. There are no coolant leaks and water pump is fairly new (10K miles). I'm going to have the coolant flushed. Its my taxi cab and would like to get it to 400K miles.

Noticed this problem by warning message of engine overheat. Mechanics told me it's water pump leakage after examination. After changing the pump, everything works fine until now (20000 miles so far).

Told when taking in for another problem on this web page (transmission pressure control solenoid failure) that had cracked water pump. Found in process of diagnosing transmission. Denied repair, decided to find someone else to do it for less. Two months out of warranty. Never fails!
