bought the wrong thing - help needed

was looking for a header tank and bought this (second one down) but it does not have a pressure cap as far as i can tell so looks like I bought the wrong thing.

Is there a locost way to convert this to to do the job or do I have to bite the bullet and buy the right thing next time ?

If it makes a difference the engine is an 03 R1

Just get a piece of tube to fit in the top hose and have a cap fitting welded to it. I have seen these items for sale somewhere but I can't remember where!!
I made my own by sweating the fitting off the top of an old Mini rad and soldering it to a 28mm copper tee.

they're also found in the top hose of a dodge calibre.

i know you're unlikely to find one in a scrappy, but they might not be sooooo expensive from the dealer.

If you attach this tank to the small tube below the cap on the radiator it will solve your problem. Fill the rad to the top, put the cap on, fill the tank half full, making sure that the water in the tank is above the highest point on the head. put both caps on and let the engine run, When the rad gets hot the rad cap seal will lift, shut the engine off and the water from the tank will be sucked into the rad and engine, after that just keep the tank topped up above the head. That is what that type of tank is meant to do.

I should have added that my radiator does not have a cap so am relying on the cap on the header tank to release the pressure

I did exactly the same and bought the one with the wrong cap.I have added a home made swirl pot header in the top hose and plumbed the other one as normal.

Dont forget the pressure cap should be the highest point on the cooling system. Wont one of the modern plastic pressure caps fit?

The expansion tank you have bought is not for the pressurised side of your cooling system. You will need to get an in-line filler for the top hose and plumb in as per Canada EH!'s post.

I believe Demon Tweeks supply the inline pressure cap.

If you bought it less than 7 days ago, you can send it back under the "distance selling regulations 2000". Presuming you bought it over the phone, internet etc, and not in person at a shop.

Nope you have got the right thing.
You just need a Fazer thermo housing that has the pressure cap in it
