Losing Coolant Slowly

[MyCord]

I usually check the coolant level once every month or so and these last two months I've had to add probably 1/2 liter of coolant. I replaced the t-stat and the 2 main radiator hoses at the end of the summer. I'll have to double check but there are no visible leaks. I would prefer there to be an external leak haha because I'm sure any internal problem would be a lot bigger of a problem..

What could be causing this? I doubt that much coolant loss over one month is normal..

Thanks

sounds like another leak from a smaller hose or it could be the radiator, look arond for any wet spots on the radiator and check the heater core hoses and the hoses on the intake mani.

Put some cardboard under the car at night and see if there are any wet spots. If not, you could be burning it... that usually indicates a head gasket problem.

if ur losing coolant ur either burning it or leaking it if its not leaking then its burning and that means something else is wrong.

do you smell burning coolant after driving?

look for coolant residue. it looks crusty green or white, but it's not actually wet, but looks like it was wet at one time or another.

since coolant is corrosive, it can eat a small pit where the coolant hose and aluminum housing meet. this usually happens at the thermostat housing. it seeps out very slowly and evaporates making it look like you have no leak.

if you discover this to be your problem, you have two options. one, you can replace the pitted cast aluminum part, which is a fix. two, remove the hose and apply Honda bond to the pitted area, which is a repair. later.

Thanks. I'll look into it further tomorrow and let you guys know.

re:leak

It sounds kinda like my problem I had. Which if it is, then it is your radiator. Basically mine was leaking slowly and you really couldnt see the leak that well. Check the bottom of your radiator. Mine was building a puddle from the leak but holding it in the lower plastic guard piece. That sounds like where your leak is. Is it the original radiator?

I remember coolant vapor smells sweet right? I need to know exactly how it smells to see if I have the same problem on my bootlegcb7

yeah it's got a sweet scent to it. that's how i was able to tell i had a problem when i was in a Taco Bell drive through.
