Expansion tank cleaning
« on: 02 August 2013, 20:03:16 »
Hi all...
Had the coolant level warning up a few times on the 2.6. Giving the float a good waggle with the pinkie usually cures for a while, sometimes months. But as it has happened a few times recently, I am going to take it off and clean it. Its a bit sludgy inside.
What is the best product to clean it with, that will not muck up anything sensitive inside. Would Jet Washing be a bit fierce ?

TIA :y

I originally soaked mine in caustic (borrowed from work), it helped in the short term, but a nice shiny new header tank is around £40 and looks the mutts nuts too!  ;)  ;)  ;)

I appreciate you say 'only £40 for a new one', but....I have not got £40 to spend on an expansion tank. There are many other things here that take priority at the moment, and swmbo will draw the line at that. Have to use the 'gift of the gab' to keep my two Omega's now. :(

So....until better times....it will have to be cleaned :y

There is no question that a new tank is the best option, but if the Missus is out for the evening, a good dose of Cillit Bang and a few trips through the DishyWashy does a good job.

Another thing you can try (I have had this problem on mine) is to turn the level sensor on the bottom of the bottle a little towards the front of the car. I found that if I had mine in the "normal" position, or facing towards the rear of the car, I would get random warnings, even with a full bottle. Turned it slightly towards the front (about 30 degrees) and it works fine now.

To remove the scale that forms, I have used about 20 pea sized stones, and a hint of bleach, block all the holes, and shake vigourously for about 30mins.  It still looks yellow at the end of it, but with none of the black scale marks at bottom.

The bottle is in 4 compartments, so getting the stones back out take a lot of patience.

However, nothing cures the float issue permenently.
