a few questions about my car...

[ollyclio]

Hi, i have a 2002 renault clio 1.2 16v, could some one tell me what type of tappets i have and where they are?
and if anyone knows the cheapest place to buy them??

also, the power steering, i understand its a electric power steering and not a hydraulic system. Where is this located and what do you do if its being lazy (like a lazy pump)??

thanks
