I have a 2004 civic LX with a weird coolant leak issue and I did a search, but found no answers to this particular issue, so I decided a new post is in order.


First a bit of history. I was driving and the heater blew cold air and the temp rose dramatically. I immediately parked and let it cool down. I limped it home as I was close and checked my coolant level, which was non existent. I replaced the coolant and issue resolved for about a month.


Last night I was driving and noticed that my heater would only blow hot at higher speeds. SO I added new coolant and did all the preliminary checks for a blown head gasket. There's no milky oil, no white smelly smoke, and coolant flows fine, although I noticed that this time when I refilled the coolant/water mix (50/50), it was a bit foamy. so I drive to work about a mile and park. After a bit, I notice coolant leaking form the rear passenger side of the engine. At first I suspected a heater core, but my passenger side foot well is dry as a bone. I'm not suspecting the water pump, because logic tells me that water pumps are located by all the belts, under the AC pump and alternator. the foamy coolant has me worried a bit because a head gasket replacement at this point would be too expensive for me.


Any help with this would be greatly appreciated.

I did a search and came up empty.
I have a 2004 lx that's leaking coolant at the back of the motor on the passenger side. At first I thought it would be a heater core, but my passenger foot well is dry as a bone. I don't think it's my water pump because if logic serves, the water pump is ion the opposite side along with the AC pump and alternator. I also don't think it's a head gasket because it's a physical leak, as in I drove it to work today and can see it dripping. I also have no milky oil, or smelly exhaust. I do, however saw that my coolant/water mixture was a bit foamy when I filled it this morning. Dunno if that means anything though


Does anyone know what is carrying coolant to that area of the motor? I have only one day off tomorrow and would rather not spend it at a shop getting it fixed, plus my funds are extremely low and If I can just replace a hose or clamp, that would be awesome.
Thanks in advance for any help you may provide.

are you SURE its coolant?...that is my first question,

second, you shouldt be using a coolant/water mixture, honda blue coolant is premixed, what kind are you using?

Heater core send and return hoses are located on the passenger side firewall

Most likely is leaking from the heater control valve:

SOMEone is gonna have to actually look for themselves and find where the leak originates.

"Borrow" a cooling system pressure tester from DangerZone and use it?
Jack and stands, creeper, flashlight, mirror, whatever it takes to see it and confirm.
