Does anybody know how to get rid of the brownish stuff that sticks to the coolant overflow tank (and most of the cooling system)? I read somewhere that using a mix of hot water and vinegar do the trick but I dont exactly remember the proportions of this mix. Is there another way of removing it?

A water blaster STEAM CLEANER IS BETTER

I would just remove the tank (remove battery and airbox) and clean it with whatever's necessary. Fill the overflow tank with dish soap with hot water, and then shake it.

Ive found that 93% sulfuric acid works wonders....

I removed the plastic tank and put in some small pebbles. Added some soap and water and shook it around. It cleaned all that brown gunk outta there.

I have that same brown gunk. Isn't that sludge and implies some sort of oil/coolant contamination?

You must be kidding right? :squint: That stuff probably burns through cement! :nono:
I just put in some sand (extra from my swimming pool filter) and soap, shaked it up a bit and sparkling clean.

Nope... that is just the dirt that comes in your regular tap water, that's why you should use destilled water with your coolant. My problem was that the lady from whom I bought the car used regular tap water with the coolant hence the whole cooling system is full of "mud".

you can also use like a baby bottle brush...that usually works pretty well...but hot water and soap works great.

I love living in British Columbia's Lower Mainland -- all our tapwater is from rain resevoirs. No spots when you're washing, and tapwater is safe to use anywhere in the car. Autoparts stores don't even bother carrying distilled water. :D

Yea.. distilled is the only way to go in your coolant system! It has no crap in it.. so it is going to shed heat better and all kinds of fricken sheet man.

No autostores around here carry water lol.. Gotta hit up the grocery store.

Hey guys... thanks for all the input... I will most probably get to this over the weekend if times allows and with all the suggestions and tips there is no excuse not have that dang tank like new. :D
