Service manual does not mention this but I need to remove mine to check it and clean it out.

I assume it's just a matter of taking the headlight out and it's underneath.

Mine seems to be in two pieces - the neck and the tank proper.

Any more to it than that?

Thanks

you can get to the tank from the wheel arch, no need to remove the headlight

(i know cos i had to change mine after i smashed it up in a prang)

 

remove wheel, inner arch lining then just unbolt and unclip, simple

Sorry to sound thick but whats the purpose of this tank?? as i know that the rad overflow pipe leads to it , but why? and whats its purpose?

Thanks guys for the help on the radiator header tank.

For Karl's question -

When the radiator coolant water gets hot there is a certain amount of air/steam in the system that expands. Without a filler tank steam would be lost out of the radiator cap at max. pressure (the pressure is applied by the rad. cap to raise the boiling point and improve engine efficiency) and the radiator level would fall a bit each time. With the filler tank there is a one-way valve that allows steam out when hot but does not allow air to suck back in to replace it when the engine cools - instead, coolant is sucked from the filler tank back into the engine system - so each time the radiator stays full but the filler tank drops a tad. The filler tank has a large supply of coolant and topping up should less often. Normally just top up the filler tank not the radiator itself. (However, it pays to check the radiator just to be sure the top-up is working and there are no leaks in the radiator cap or the coolant line to the filler tank.)

My best advice - never EVER use straight water otherwise you are going to kill your engine - always use a good quality anti-corrosive coolant (with or without an antifreeze, depending on your climate). The newest and best anticorrosives are now in the market and use organic chemicals to fight corrosion rather than the older anticorrosive salts. The older salts are anticorrosive but still promote electrolysis between the engine metals. High concentration antifreeze - ethylene glycol (>~1000gm/litre) I think also minimizes corrosion.

Hope this helps.
