I'm building a 2.0 zetec turbo using a black top zetec out of a mondeo(block where the oil filter bolts to the block not the pump).
I have got to use a 2.0l water pump as the 1.8 pump does not fit the block the engine is going in an mk6 escort so the alternator can not go at the back as the enging mount will be in the way.
can any one help me or let me now how to run the belt so that the water pump will pump the right way with the alternator at the front of the engine as the 2.0 pumps the opposite way to the 1.8.
please please please help some one i'm really stuck.
Thanks in advance for any replys.
Thanks,
Phil

 

the water pump will run off ur cam belt mate not ur fan belt

 

You're full of great advice tonight

 

You will have to modify the 1.8 pump to fit the 2.0 zetec and mount the alternator at the front. I am sure the cvh alternator bracket will fit.

 

On a zetec engine the water pump runs off the fan belt

 

can't use the cvh alternator bracket i need to use the zetec one as it also holds the power steering pump too.
Modding the 1.8 pump aint gonna happen need to mod the 2.0 one some how and get it to spin the other way.

 

what you need is this mate




Thats a clockwise rotation waterpump and modded escort pully but before all that you had better make sure that your alternator and PAS bracket fit the engine correctly witht he blacktop water pump housing.

If not then you can have the block drilled out to make the silvertop waterpump fit in the correct place. Can't find the thread at the mo try looking on google for it i dont think it was on passion ford

 

AFAIK the machining of the block to suit a silver top/CVH pump is for a ZVH conversion (or silvertop head) as the blacktop cambelt goes straight over the block waterway. This was always a problem/issue with the WRC engines.

Although a reversed impeller will work (PF said they were getting one from USA for Project Peanuts) I wouldn't think it was too efficient as the pump housing is cast to suit the designed rotation.

PF did say (for Project Peanuts) that Retro-Ford had a solution, presumably for RWD primarily.

The other option which will work, is to just remove the impeller fins and use an electric pump.

 

Hate to tell you this but the reverse waterpump is actually a Ford recognised part the waterpump is not made by Ford but the engine it comes from IS sold by Ford racing parts dealers in the USA. The pump above came from the same people that supply Ford.

It don't matter what way the pump spins all it has to do is suck water through from the rad and into the engine, the pump housing is not as complex as your thinking.

 

Come on, you don't really hate to tell me what I already know about it being a Ford Racing part.........

Its one thing Dave actually got right in his write up.

I'm wasn't saying that it wouldn't work, only that its not as efficient as the standard rotation. The pump is a centrifugal design with a volute chamber (like a turbo) with the offtake in the direction of rotation. A simple centrifugal pump simply has an anular space and an offtake perpendicular to the driveshaft so the coolant turns up to 90 degrees to exit. With this impeller and reversed rotation it has to effectively turn 180 to exit the pump casing on its way to the block.

As I say, it doesn't mean it doesn't work, its just not as efficient on a pump that can be marginal anyway on some installations. Ever seen one that's suffered from cavitation? Its not nice.

And i wonder who told Dave about the pump oh yeh it was me lol.

I do see your point now you have explained yourself correctly.

 

I'm sorry but I don't see anything incorrect in my first post. It was a simple statement of opinion based on my knowledge. I hadn't realised that it needed an explanation

I kept it simple as in other Forums its been commented that a full technical explanation is indigestible. That's also the excuse given to me for omissions and some errors in the 'comics'.

ok I'm so lost in this thread. Not really understanding where to get the pump that is pictured at.
I'm in the U.S. and the pump I have is reverse rotation (counter clock wise), I need a clockwise rotation water pump. Can someone explain what car the clockwise rotation pump comes from?

If anyone needs a counter clockwise one, I'll trade straight across... or work something out.

 

I got ya PM and replyed mate

 

sorry this is my first post here. i am also wondering what inis asked. if i can get some help it would be much appreciated. thanks all.

 

if using the blacktop engine you can get the whole on the side made bigger to take the 1.8 silvertop pump.

 

True NATH-RSZT, but don't you then have a problem in that the cam belt routing is in conflict with the water pump?

I believe the belt routing was changed as 'a minor' improvement in reliability and longevity as the belt engagement with the Cam pulleys (particularly on the exhaust) is increased. That then cascaded into the pump relocation, which was 'over designed' with a 'handed' body.

So would you have to convert to Silvertop head as well? And then, as you couldn't use the Blacktop engine mount/centre cambelt cover......well I suppose that's not an issue if your already doing a swap requiring fabrication of custom mounts.

I just wonder if its not just easier to start with Silvertop in the first place ?

what i did was use the standard 2.0l water pump with a mk6 escort alternator bracket but i cut the top half off the bit that the power steering pump bolts to and then used the 2.0l power steering pump and bracket this allows you to run the pump the right way with the only mod being the cutting of the alternator bracket took about 10mins with a hack saw. if i can figure out how to post pics i'll put some up. hope this helps.
