Antifreeze leak

I've been noticing an antifreeze leak lately from my car that seems to happen sporadically. It started with fairly big puddle, but has only been a few drips of late.

First chance I got I checked under the car, felt around the hoses and the radiator to see any sign of it, but didn't find a thing.

I also noticed from time to time when I turn on the heater that I can smell it through the vents then it goes away. So I'm thinking heating coil, but I'm not sure where that is. Or maybe its leaking somewhere hot and evaporating so I don't see it.

Any thoughts or suggestions are appreciated.

Same thing happened to me... I thought It was the radiator... got it changed, still had the problem.. turns out it was the water pump

oh well... solved my problem... check the water pump and your radiator.. just in case.

We had a leak from the radiator, added some sealant...whoops, the radiator was clogged.

We got a new one, but the car still smells of burning coolant- a delicious carmel smell that I kinda like.

I've replaced the water pump in my other 2 Nissan/Infinitis though. I was surprised when that wasn't the problem in this one.

I had leak on my 2000 SE for a while too. It was the upper radiator hose, which happened to be way too close to the radiator cap. It had a microscopic hole at the end of the very loose opening of the hose. I just cut off an inch, and then repositioned it further away so that when I opened the radiator cap, it wouldn't scrape the hose and force the opening to go loose.

No problems ever since.

Thanks for all the replies. I'm gonna have a closer look at my water pump to make sure since all the hoses all check out fine.

My 2000 SE had the same problem. turned out to be an upper hose in front of the engine. I just replaced the clamps on there with new ones and tightened the sh1t out of it. Havn't had the problem since. It would usually happen in the winter when it got real cold too.

It wasn't a nissan, but my buddy's Jeep Cherokee was leaking antifreeze, replaced the water pump, no more leak.
