Looks too tall....

How much David?

Says 200mm tall but I can check for you tomorrow. How about £35 including postage?

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

I've measured the gap, and thats going to be too tall I'm afraid. Thanks anyway.
Found that Forge do a Renault 5GT tank which looks perfect.

No probs, if you dont wanna pay forge prices then a cheap alternative is obp do one the same as mine but horzontal, ie half as tall..



Or they do a square one 150mm tall with either style cap ..

Found some old videos of me competing in 2003, with the Zetec and very short final drive (later changed to a much more reasonable one)

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

Ordered one of these

from www.evaluation-designs.co.uk

Ordered a pair of new Tri-lobe joints from M-Sport, so I can send one off to Commercial Propshafts so they can finish off the shorter axle bar.

The snapper from Fast Ford has been in touch and we're planning on using Shelsley Walsh for the photo shoot at the end of September. Just need to clear it with MAC on Monday.

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

Header tank has arrived


And the 500mm long 32mm ally pipe to connect the rad to the inlet


Plumbing it all together tonight.

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

Header tank install started (Tuesday evening). I'll complete it over the next few days.

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

as always , ultra neat!

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

All plumbed in.

New Header tank now on the drivers side.
32mm alloy pipe now runs across the width of the radiator, saving a bit of weight in the process.

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

safer than a bit of flexible pipe drooping across there too .

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

I know, that looked a bit gash too.

Here she is with water/anti-freeze mix loaded, and the airhorns back on again.


I'll run the engine up to temp tonight and bleed the system.

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

Ran the engine, but I'm still stumped by this odd cooling problem.

Header tank is now plumbed in to the thermostat housing, and when the engine is running, I get a constant stream of water being returned back to the header tank, from the 8mm pipe I've run from the outlet on the gearbox end of the head. (item 8 on the diagram below)

The bypass pipe is still connected. This allows water to circulate in the head prior to the thermostat opening.

But from cold, the engine warms up quickly, then the temperature continues to creep above 95 degrees, at which point the ECU turns the fans on. But the radiator is stone cold. The outlet pipe on the end of the head is hot, and the header tank contains very hot water. But the engine doesnt seem to want to draw cold water in from the radiator.

When I revved the engine, the water temp dropped to 80 degrees, and started to creep back up to 95 again. I couldn't repeat this, and I suspect it was an air-block which was cured by revving the engine.

Any ideas? I've bled it, the header tank is full, when I rev the engine the temperature seems to drop and stays at a sensible temperature. But when it idles, the temperature seems to creep higher and higher.

It should isotherm around 90 degrees shouldn't it?

Do I need to block off the large diameter bypass hose off, on the front of the block? Do I just leave the system to pressurise itself, and it then sorts itself out?
Is there an eejets guide to cooling systems somewhere as I'm confused.

I suppose I should let it cool down, and try again a few times from cold, to see if the problem persists.

This is the Ford diagram for the Fiesta ST cooling.

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

I can't help you with your immediate problem there Graham, but perhaps a good excuse to go for an electric water pump system? I'm not sure if that changes the plumbing etc though? Give Steve broughton a call, I'm sure he'll probably be able to help you out.

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

I think thats the next step, but for now I'll focus on trying to repeat the problem from cold.
It could have been a one off. Doesn't appear to circulate water from the radiator unless its revving, so at tick over it starts to over heat. This is what it was doing at the rolling road, over heating at tickover, as Troy had to keep revving the engine to get the temps to drop. We put that down to the header tank setup, which I've now changed.

Its back on the trailer ready for the photoshoot trip to Shelsley on Thursday, so I'll have another try then.
At least it doesn't leak 8-)

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

not knowing on what is your problem, but I do like the EWP80's.
Used them on 3 engines and the only problem I have seen on them is when another Caterham owner put one on his Duratec and did not remove the belt driven pump, ended up with cavitation and a shagged head.

My 270bhp engine has run for 5 years with the EWP80 without fault in temperatures up to 50+ ambient and 60+ track temp without problem. When first installed it dropped the temperatures at tick over by about 10 degrees. It also gives you a few horses by freeing up the belts
