Escort and Fiesta silvertops share the same type, correct for rotating the same way as the engine. Mondeo silvertops pump rotates the wrong way but can be swapped for a Escort/Fiesta type. Blacktops (fiesta, with plastic cover, and duratech branded st170 engines) have only one pump type, which needs an idler, or the impeller (and pulley) changing.
Interesting. Have you done this? If this is the case I'm'm surprised the likes of IK engineering have 'tooled up' to make there own reverse direction impeller.

Thanks, but as this is my engine I happen to know what it is and as I say, it's a Black Top machined to fit a Silver Top water pump and cambelt kit to avoid using an extra pulley.
And with regards to pulley - yes. But it doesn't spin it the right way round still for the reasons you yourself described above, so we machined the block for the Silver Top set up instead. If I was running a lower spec/less expensive engine I would just use it like that anyway as I've heard of people doing this with no issues.
