Coolant Leak

lo folks i noticed the other day that the coolant warning light popped up on the ole dash, i never thought much of it tbh and checked that the level was low

Topped it up with coolant which cost £14 :poke: and thought nothing more of it, two days later the warning light popped back up, so once the car cooled down a little i re checked the level.

well it was well below minimum :( however i could not see any leaks anywhere so i thought i'd give the ole girl a scream around the bypass :driving:

popped the bonnet and looked down and seen a puddle of water/coolant sitting on the floor pan :cry:

using a torch it appears that its dripping off the bottom of the trans cooler, which confused me because i thought it was oil cooled (n00b) lol

anyhow after a bit of research it appears that the trans cooler also gets fed from the radiator? and that it heats the transmission oil when cold,

Anyone had this before and can give me any advice, much appreciated :thumbsup:
 
Are you sure int not the expansion tank. I have sim miler issues at the moment and mine looks to be the tank. It's a known problem with the e46. I can see a very small amount of water on the top of mine. Just need to take the plastic slam panel off to have a good look. It's a £70 part.

Witch ever hope you sort it soon :thumbsup:
 
Machine Monkey you are totally right and thanks for your input m8 as it sits above the transcooler, anyhow with a bit of research, managed to pull it out and here is the evidence
