Anyone got any tips for cleaning the inside of the expansion tank? Mine is so stained I can't tell what level my coolant is at! Was gonna buy a new one but Alfa have made the part obsolete!

Maybe parts cleaner and then good rinse?

iv heard a mixture of bleach and washing machine powder does the trick, but cant remember exactly how its done. I'll see if I can find the thread I read it on, probably another forum so I may turn up with nothing lol

maybe do a google search and see what comes up?

strangely enough Naan is right.

I took one out of an 8v 155 i stripped that was as good as black inside.

Bleach, 100%. block up the holes obviously

Leave for a few days

Rinse thoroughly.

was SPOTLESS.

Soak it in a bucket of petrol for a day and watch the grime and crud fall out of it.

I've got a spare expansion tank and it's been submerged in my parts washer for about a fortnight, look pretty clean now.

Or if you want a really clean polished look,then buy a polished stainless steel tank or get 1 made.

Thats what I did.

I would like to know if any of the receipts above have worked well!

I've washed mine one with a mix of water, bleach and soap... with some grinds inside and shaked it.
It has cleaned but it is not completely cleaned yet! I would like to have it like a new reservoir.... unsure.gif


One thing you can always do is to buy a new expansion tank that equips Fiat Brava, Bravo & Marea (I think this one Fiat still supplies)
It is the same expansion tank that equips Alfas 145 phase 2, and it fits all 145 models. Just plug and play.

The only thing is that you will have to pay attention and change the cap of this new reservoir, once on the Bravas and Mareas
the cap is calibrated to 1.4 bar, and in our Alfas (at least the alloy top version....) the cap is calibrated to just 1 bar.

BTW, does somebody of you know where to buy new genuine 1bar Alfas expansion tank cap????

Seal off both the outlet pipes with some old tubing and jubilee clips, drop in 2 or 3 dishwasher tablets and fill with boiling water. Then leave to soak over night! thumbsup.gif

Keep left unless overtaking - Use mirrors and signals when changing lanes - Keep within the white lines - Don't tailgate

Its not exactly f**king rocket science is it?

My expansion tank was thick with brown gunk and I couldn't see the coolant level anymore, so after reading this thread I thought this would make a good, quick holiday job.

I tried the dishwasher tablets - it made it better, but not great. I then filled it with a bleach solution overnight (didn't have enough bleach for 100%) - again better, but not as good as I wanted.

I then trawled the net for other ideas and putting detergent along with rice or gravel in the tank and giving it a good shake seems popular. Not wanting to turn the Alfa into a Nissan, I went for the gravel option.

Out to the garden path for a handful of pea gravel and into the tank with a bit of water. After shaking it for 10 mins, it was looking really good - not concourse, but clean.

Then came the hard part - because of the baffles in the tank, it took nearly an hour of shaking, turning, twisting and swearing to get all the gravel out again! It was like one of those infuriating puzzles where you have to get the ball through the maze - except you couldn't see the maze!

The tank is back on the car now and looking good, but looking at the colour of the water, a radiator flush is the next job.

Cheers,

Mark.
