97 7.3 E350 Coolant leak passenger side

I have a 7.3 Powerstroke and I just noticed after I parked in my driveway last night that there was coolant leaking from the front passenger side of the van. Took a quick look (it was raining) and couldn't tell where it was coming from but it looked like it was only a few inches up. Does this sound like a new water pump is needed? Or are the symptoms something else?

It could the water pump but that should be more dead center than to either side... check your lower radiator hose, follow it up from the radiator to the engine my clamp has come lose once and it also cracked once which caused a similar leak. Wish I could be of more help...

The 7.3's oil cooler is on the driver's side, as are the coolant tank and bypass hoses. I think the lower radiator hose connects to the radiator on the passenger side. A thermostat housing seal leak and upper rad hose will dribble down under the front engine casting, about front center. so will a water pump seal leak. The fan will push the drips all over the place. Best to hose it off with clear water, fire it up and crawl underneath and look for colored water dripping.

I agree clean it up first then you should be able to rent a pressure tester for your coolant system. With your van off and cold hook up the pressure system checker and it should reveal any leaks you have with ease.
