Clothes peg on the black hose (to stop escape of coolant from radiator).

Basically I want to give the inside of the reservoir bottle a wash out. Is it easy to remove from the car- clean then replace? (and refill with correct mix of water/coolant of course).

Any potential pitfalls- i.e. need to burp the car etc? Should be straight forward?

I removed mine a few years ago and I remember it as easy. Get a work light and poke your head in there.

any special tools needed? Should be straight forward.

Ive previously changed the engine air filter and cabin air filter myself so should be similar in technical terms?

The "special tools" I once used to rinse the inside of the reservoir on an old Volvo, were a handful of cleaned gravel. The tank was covered with residual slime, but with gravel, water, dishwashing soap and quite a bit of shaking it got impressively clean.

I mean tools to take the bottle off! :icon_rolleyes: :icon_biggrin:

Small adjustable spanner ok? Is it relatively easy to reach inside, undo then redo? Im guessing there is only one way into the reservoir. There isnt a bottom hole in the bottle is there? Plus there are no thermostats etc attached?

It looks like its a simple couple of screw adjusts then it lifts out/back in?

socket set with extension, gloves, light. I think it took me about 3 minutes to get it out. Easy. Dive in.

mine has 2 small 10 mm head bolts at the top. the bottom has a rubber washer/grommet type part on the tank which fits into a bracket on the radiator surround if i remember correctly. there are no bolts on the bottom is the point. you just carefully lift up and wiggle after removing the bolts and it should come right out.

edit:
if it's that dirty you should get all the coolant in the system replaced too.

I had a lot of trouble getting the inside of my overflow bottle cleaned. There was a residue buildup that didn't just 'rinse away' even with vigorous shaking. I had to use a long bottle brush. Actually, I used a 'clothes dryer lint screen holder cleaner' which is essentially the same thing. (I didn't want to use any harsh chemicals as any leftover might find its way into the engine.)

Thanks guys- possibly the easiest (yet strangely the most satisfying thing I have done yet).


A simple cocktail shake of hot water did the trick and in all it was done within 10mins max.

Next is the screenwash bottle- that does have black (mould?) flakes in it.
