Also very good, especially for expansion tanks, are extra strength denture cleaning tablets. I bought a tub (with a lid) bigger than the expansion tank, put half a dozen super-strength Steradent in, topped it all up with hot water and put the lid on. Gave it a shake to mix it then left it a while. gave it another shake to help the dirt start loosening then left it overnight. Another shake first thing in the morning then in the afternoon (when my hot water comes on) another shake before rinsing it out and drying it. Either way, the dishwasher is a very good tool for cleaning expansion tanks, washer bottle reservoirs, wheels, anything in fact that will fit and not be damaged by high pressure water being sprayed into it!

When I cleaned my washer tank and the header tank a few years ago I used 'Oxy Plus'. It's one of those foaming oxygen laundry and general purpose cleaners like Vanish or any of the Supermarket own brand products.
It worked well, but I still had to give them a second go and use a bottle brush in some hard to reach a places! |

On mine (B280E) the dizzy is at the front so the water sprays down onto the left hand exhaust downpipe as it runs over the top of the bellhousing resulting in a cloud of steam when that valve failed. You might find the blockage is actually in the jets as well, if so, these are a worthwhile improvement : https://www.ebay.co.uk/itm/Windshiel...0/352558440677 Easy to fit, pull the rubber hose off the old jets then using an 11mm box spanner or deep socket, align two sides of the socket with where the tangs will be and push up towards the bonnet which will disengage the tangs on the old ones and the old jet just pops out. Feed the hose through the hole, attach to the new jet and simply push the new jet into place. Test, enjoy and spend hours watching the screen get cleaned quicker and easier! Somewhere i have some photos and even a video of how effective they are, can't find them at the mmoent but definitely a good improvement!

Right up until she finds out, at which point much explaining will be required, together with a trip to the hospital to have the items surgically removed!

Should I do it again I might take the dish washer tip and gain a load of brownie points by loading it and stacking the 'plates' the next morning. Trouble is that gesture of goodwill will undoubtedly raise suspicions that I might be up to no good! |

A bit like i have cleaned catalytic converters with dishwasher tablets, similar procedure, half a dozen dishwasher tabs instead, cat in a container big enough then flushed it through with the garden hose both ways afterwards before drying with compressed air and painting it. That was after the Lambda sensor on the front bank had failed during the previous MoT test and i'd watched the CO level rise from 0.06% to over 9.5% when the tester pulled the hose out of the tailpipes. Got a clean sheet (every pun intended!) on the emissions afterwards but the tester was wandering round asking why he could smell lemons!

The T shaped valve with the red top which feeds the window washer.There is a rubber diaphram inside which perishes.This then stops water to the washers. Take the valve off and you will see a small hole in the red top-something someone else can explain to me,it's an air hole by which the Volvo sorcery works. Take a fine blade between the red top and the black body and gently lift and the red top will pop off. I use a very thin rubber disposable glove to cut a small piece to make a new diaphram.Make it too big then stretch over the hole and a good steady push with the thumb and the red top will click back on. Have tried to upload a photo of the spare I carry---probably won't show.But it does'nt need to be a neat job.Bet you find it works |

Hopefully view of the valve from below. The blue is the rubber glove diaphram--you of course are allowed to trim it so that it looks nice. Last edited by mike1950; Jun 26th, 2019 at 02:36. Reason: addition |
