What is your question?
Hi all, I’ve got a coolant leak coming from the front of my engine, so I’m assuming based on the resources I’ve found that the water pump should be replaced. I have no oil and coolant mixing so I’m assuming I can rule out head gasket or engine block leaks, and I have a few questions related to this problem. Is there a good way to check that the leak is from the water pump for sure? I haven’t got the most experience working around the engine, and am a bit hesitant to change the timing belt, but I’ve heard that it’s a good idea to change it in tandem with the pump. How should I check if it needs to be changed? And if not, should I pursue changing the water pump without taking the belt off? I’ve been using rockauto for most of the replacement parts I’ve used on this car, is that advisable for these fixes?

Hello, I’m Pete from the Car Genius team at RepairPal. I’m sorry you’re dealing with this concern on your 2006 Subaru Impreza. A coolant leak is something that should definitely be checked into to prevent engine overheating concerns. Cylinder head gasket failure can be common, it's good to hear you are not seeing any fluids mixing but doesn't necessarily indicate that a head gasket isn't leaking as in some cases they can leak externally. The best way to identify the cause of the coolant leak is to have the engine cooling system pressure tested with a coolant pressure tester (most all shops have one of these). This will quickly help identify the cause. Water pump failure can be common and since the water pump is run by the timing belt on this model it is a good idea to have the belt inspected or replaced if the water pump is replaced. I recommend checking for any cracks in the belt or missing teeth or uneven wear which can indicate the timing belt needs to be replaced. On this model Subaru recommend replacing the timing belt every 90,000 miles. In my opinion if the water pump is the culprit I would replace the timing belt at the same time. RockAuto does offer multiple choices for many parts, when shopping online I always recommend to look for good quality OEM or direct fit aftermarket OEM grade replacements and not the cheaper options as in some cases the cheaper parts may not last as long or may not fit as they should.
