Good morning everyone and hope y’all are ready for Christmas! I have a constant drip behind the passenger wheel dripping off of the inner fender well. It started in late fall while still running the ac and I thought it was just dripping from the condensation tube but nope! Checked the heater hoses and no leakage there but my main clue was when the wind shield started fogging up. Floorboard and carpet is dry so I don’t think it is leaking in there. The drip is constant at about one per minute when there is no pressure on the system and a couple every 8-10 seconds when pressure is on the system or has been warmed up. Everything I have looked at on the engine and passenger side area is dry so I think is is somewhere near the firewall. Can anyone tell me where to check for this type of leak or what to take off to see? Thanks in advance for the help!

 

Mine drips at same location, but its coming from the Ranger Valve mod, that I added. IF switch is in any position besides the feet position, it makes the valve drop coolant... Other than that, I check this plugs that are removed for a full service coolant flush

 

Is it just water, or is it coolant? If it's coolant I'd expect that you're looking at a heater core, if it's water I'd suspect that your drain tube for the A/C is plugged up. It, too, will hold water in there and cause fog up.

 

Yes it is defiantly antifreeze and your answer is what I was figuring but hoping there was a drain valve somewhere up on there that might be leaking.

 

The only drain valve I'm aware of is on the bottom of the radiator on the drivers side. However, I'm still learning a lot about 7.3s so there might be another one

 

Thanks for the help!

 

Don't forget to follow up with findings and results and we like pictures of the offending areas.
