Yes, echo that, if you leave that as-is you will find your cooling is even worse than before. Now the radiator fins are at such an angle and you've not blocked off around the radiator to actually force air *through* it, the air will find it far easier to blow "up" the slope/ramp of the radiator face and over the top into the engine bay. This is a very common problem on kits, angled radiator or not. There's some in-depth F1 article about radiator angles that I read once, probably show up on an internet search if you're interested :D....

Hi all, since the last update it became obvious that even though we had added the header tank to the system it didn't actually seem to be doing anything. A quick look into the cooling system showed that the header feed pipe had rusted closed, and also that the thermostat had perished and needed replacing. A quick visit to the local shop and we were on our way back with a new thermostat, spark plugs and timing belt. It was surprisingly easy to drill out the header feed pipe and reassembling only took a couple of minutes. I have added a few pictures of the process of changing the timing belt, we used the old cut it in half down the middle and slide on the new one then cut the old one technique. 

Unfortunately when once everything was changed and installed we went to start the engine only to quickly realize that we were only running on three cylinders. It only took a minute of searching before one of the HT leads fell apart in my hands, parts are on order and will be here Tuesday. 

Brumster, yeah that's the plan. I am thinking of making it out of a single sheet of plastic and then cut out the shape of the radiator and have it really snug in the nose cone. I couldn't find the F1 article you mentioned but I did find a few interesting Youtube videos on the subject which have given me few ideas for how to implement it. 

We still have some concerns about the mounting for rear shock absorbers  and the seat belt mounting points, could any Exmo owners show us pictures what you have done? I'm not sure what we have is good enough for the IVA.

Thanks for reading

Nick

Hi,

Just seen your threads and notice the cooling issues you have had. As you are now fitting a header I have a non vented radiator off a VW Polo diesel (new) which is plenty adequate for stock pinto applications - no charge just give a donation to charity, this would allow the rad to be more vertically mounted. If you continue with your positioning you may have to carefully direct the air flow even to the extent of adding mid fins as there would be a tendency for the radiator to only be effectively cooled at the top due to air damming. I experienced this with construction equipment applications where heavy duty fans had to be fitted operating constantly to maintain efficiency. 

I had problems fitting radiators in mine car but mostly due to the requirements of fitting a large inter-cooler which I had to mount in the front, my offbeat solution was to fit a side pod with 2 formula Ford radiators (long but high capacity) also a Kawasaki unit directly down from the header tank and turbo. All this has resulted in an extremely cool running engine with only about 50kg added to overall mass, useful in an engine with high power potential and allowing all of it to be used.

I can get you some photos of S7 next time I’m over working on it if it will help, won’t be for a week or so though.

what rear shocks have you got?

I have 4 point harnesses and for mounting the rear mounts go through the top lip on the rear panel and through a piece of box section that is welded into the load spreading plates for the rear shocks.   The lower harness mounts go through the panel at the back of the seat into the standard harness eye load spreading plates, but I was required to also add some angle iron on the inside to brace that panel so it wouldn’t deform in an accident.

Thanks Mr Toad that's a kind offer, but for the moment were going to stick to our current setup, after all the hours and money we have now put into installing it we want to see if our handy work makes the difference to the cooling (though you may get a panicked message of us if it doesn't). 

The Duck, yeah that would be great thanks could definitely do with some advice on this one.

I will attach a few pics of our current rear suspension and our rear roll cage and you can tell us what you think. We are planning on adding 4 point seat belts to replace the ones in the photo. I'm assuming we will be better off ditching the current rear shocks and spring for a coil over option in the space the spring currently uses with a bit of strengthening? if so does anyone have advice on where to find something that should fit in current set up with little modification?  

Cheers again

Robin Hood did a coilover kit/upgrade for the Exmo that put it all where your current damper is, and the existing spring just went bye-bye (the space left empty). You could make up something similar although obviously you would need to make your own mounting plate for the top - I wouldn't re-use the RHE one you have for the damper. You want something with some strength in it, maybe pick up/extend the red bracket you have there that mounts the rear section to the tub. *If* you decide to go that route :) it won't make the thing magically handle any better though so I wouldn't get too tied up about it.
