Can't find the source of coolant smell.

I wonder why my car was smoking out coolant for a week and just stopped? I mean the only other time I had noticable coolant loss was durring the header install my bro accidently loosened the bolt where the lower coolant hose goes into the block, what a dumb ass lol.
 
Are you sure it was coolant? it could have been vaopr and moisture buildup in your block from sitting a week. cause the only way to burn coolant is from a warped head or blown head gasket.
i marked a line on my overflow bottle yesterday and am gonna watch it for a bit to make sure im not loosing any. i dont mind the smell as long as its for no good reason.

yeah, maybe. but it smoked long enough for me to have to take it to the dealer.
 
me too

i find that i can fill the coolant tank and a week later it will be half way to the add line.
no signs of leak, cant say i would recognize the smell, but its certainly going down. even wierder is that once it reaches a certain level, i dont lose any more. it will only go down that halfway to add and sits there, so i dont worry about it.
 
i dont have a msp, but my dx has the same problem...cooling is going down few drops at the time...well, this has been like this since 2004. i replaced the coolant reservoir last year, and all the hoses too...
finally, it happens that i do have a very (but very)small leak on the radiator..well,i am just going to replace now (found one on ebay)...
so,anyway, the car runs more than fine for the last 3 years with this little leak...drove from FL to CA and return,and the car has more than 115000 miles on it!!!!!!reading this thread, it seems to me that all protege use a little coolant,nothing wrong with that!!
 
Heck, mine has smelled like the radiator cap is off ever since I bought it new in Feb 03. I have a 114,000 miles now at 13-17PSI (on two different turbos) and it has never, ever leaked a drop.
For some reason you can smell the coolant in these cars.

Its another feature of the Mazdaspeed. You can try to replace the clamps on both ends of the coolant hoses. I think those spring clamps loosen up and expand due to heat and age. I also put a small clamp on the overflow hose off of the fill neck, as I noticed some antifreeze residue there once. I don't have any leaks, but I get a coolant smell constantly. Nothing like the smell you get with a blown headgasket or cracked head though.

I did this and it solved the prob when i was experiencing what you all are describing...there was a leak which would only drip a few drops at a time but you could see where the coolant was dripping. The factory clip just wasnt tight enough to deal with the expansion and contraction of the hose...put on a t-bolt clamp and its never been better.

Hi, sorry to revive this thread, but i'm also experiencing some coolant leak, few drops at a time, saw it when i was changing the oil. I only have 31000KM on the car. No visible coolant anywhere near the radiator or hoses. Not sure where it's coming from. My reservoir level keeps going down bit by bit. About to go in and do a pressure test. Not sure if it will solve the problem. Any more advice out there?
I have a Radiator Leak and it is slight enough that the coolant never hits the ground. The coolant that is leaking gets trapped in the plastic housing underneath the front of the car. Never noticed leak until I saw Resoivoir was getting Low and took a flashlight staight down under radiator with my hood open. There was a green puddle caught in the plastic crevice. So it never hit the ground since the leak is small.

Get a pressure test done to fine the source. It worked for me.
