1998 Acura CL Q&A
1998 Acura CL Question: How can one determine if there is a water leak in the water pump.
Pressurizing the cooling system will indicate/locate a coolant leak. The way an automotive shop would locate the leak is by removing the radiator cap and attaching an adapter that screws on in place of the radiator cap. Something that looks like a bicycle pump with a pressure gauge attached to it is used to "pump up" pressure to simulate pressure generated when the cooling system is at operating temperature, the leak is then found sometimes it is obviously leaking from a coolant hose or cracked housing, failed gasket or water pump, sometimes the engines cooling system needs to be inspected from below or inspected using a mirror and flash light. If the coolant loss is still evasive dye can be added to the cooling system that may indicate the source of the leak. - patrick mannion
look at the timing cover. if the coolant is coming from under the cover it is most likely the water pump. You would need to take the lower cover off to be 100% sure. Most companies offer a lifetime warranty on the part. the problem is the labor is not :( - Merrimack Auto
