I purchased EXPANSION TANK Part No : 174RE0100 for Ren clio 02 plate from the Poole Branch The quality of the tank was terrible, I had to get a craft knife out, cut away at the excess production plastic inside and out, had to use a screwdriver to poke clear the coolant holes of plastic. Where the tank was molded together as two parts the mold didn't line up so the cap wouldn't fit, I had to cut away at the plastic to make it line up, when it came to fitting the tank one of the bolt holes wasn't the same size as the original part, I had to drill away at the plastic to make to bolt hole bigger and eventually it fitted.
