Coolant leak

Tracking down a few coolant leaks in a 2000 sport. A new radiator took care of one; however, Iím also seeing coolant drops collect on the back of the front differential (see pic). Is this consistent with a heater core leak?

Re: Coolant leak

No picture, but nonetheless, no, that would not be consistent with a heater core leak. A heater core leak would probably show up in the passenger footwell. A coolant smell inside the cabin and a damp carpet are your usual clues with a heater core.

I would start by inspecting the weep hole at the bottom of your water pump. Use a mirror and a light. Look for a coolant trace/path down the water pump casting. It might also follow along the bottom edge of the lower radiator hose.

Re: Coolant leak

No, fortunately. Heater core is usually passenger side floorboards. Check the weep hole on the bottom of your water pump for evidence of leaking (very common and means you need a new water pump ASAP). Also, check around radiator cap and check the overflow hose that goes from filler neck to the coolant tank on inner passenger fender.

Re: Coolant leak

Have the cooling system pressure tested.
