HAHAHA i have no idea which is why its taken me months to sort the cooling issue/setup So blank off the heater out pipe, pipe the feed from the header tank to the heater inlet and let it pull water through the header tank and from the top of the radiator? Big late back to the party - Yes - oh you did it already - Looks like you have a healthy volume of water in the system as well. Apart from a medium/high power two speed fan I think you have it about as good as you can - If you went for more power - Is there room for a R8 style installation? You could possibly put a custom rad there but space between the engine and rear panel is very tight. If i have more issues after this the tried and tested front radiator method will be taken. The block was already filled with water from a previous test but i think it took over 7 ltrs of water. Ill do a proper drain down and measure the systems capacity at some point.

how any miles have you done in it now? wouldn't there be signs of it blowing, black soot and such? have you inspected the turbo itself to see if it spins freely or if there are signs of it making contact anywhere on the housings?

hmmmm food for thought. The circulation thing makes sense, when i tested it i did have the feed and return looped so maybe i will do that instead of capping them off.
The way ive planned to plumb the header tank was based on some vw setups, i assume it still pulls on header tank as it feeds into the bottom rad hose before the pump.

ive got a really big want for one of these, good find. Clio 172/182 engine should drop straight in for some extra poke and the 197 lump with some modifications #justsaying props on the a menu too lol There’s a 1.8 16v Laguna on eBay now, only £375, been looked after. Grab a bargain! just found it, next town over too so super close. cheers for the heads up

Oh wow, it's so hot today so I havent completed as much as I wanted. so this was the final testing lash up. Pulled it all out to make a start on measuring for hoses and brackets. When I took the rad from the scrap yard i took the support brackets too. So they were re bent to suit how I needed them to secure the radiator properly. I've moved the top over another 2 inches than I had it so I could mount it nicely and reduce the air space/gap above it. It also lowers the height slightly so the header tank is effectively higher than it a touch. That's as far as I've gotten today.

Great info there cheers, i will definitely keep one in place, i think the new setup feeding water to the bottom rad hose with an air return from the top of the rad is better than my last attempt of fitting one inline on the heater pipes of the pump. Once this is all done i will be pulling a favour and running it on a dyno at my mates house. Then all being well i might be able to go for a little more power (but more a sporty noise than anything). Would love a snorting side draft and tasty exhaust on there eventually

ha if it was so simple.
The shopping list is growing again to get it all finished off or at least usable. I need a new header tank, i really don't like the ones i have but have found some aluminium barrel ones that are horizontally mounted that look like they could work nicely. Need to order some wiring for the fan (any ideas on what size i should buy?) and some for the alternator. I'm guessing my 30amp 6v relay will now need to be put aside for a 12v version with integrated fuse? Some ali and silicone pipe but i can get that from forge motorsport. I need something to make panels off to block off all the air around the radiator. The old stuff that ive used has been chopped so much its not usable. Something light and easy to work with, the current stuff was an old safety sign or something, like a lightweight but thick plastic? All new bulbs for the car, flasher relay, a few voltage droppers for the fuel gauge and temp gauge and ive been told i can use a rheostat for the wipers. Oh and a battery, the local scrap yard sells them back off tested good so ill just pick one that fits the battery box. I'm off work again for a week as of the 24th so id like to have it completed then to use it a little.

Glad you’ve got it sorted Adey. As it happens it was Calsonic I used to work for. Hopefully sorted 😁 as it seems good ill spend some time sealing off and plumbing it abit better then test again once the electrics are in place. Today was kinda hot too so I really do hope it's now sorted. Cheers for all the help with it all to you and everyone else that have chipped in 👍🏻

The alternator will also increase the voltage which will result in a good increase in the power from the fan. There are also some very powerful 2 speed OEM fans out there - so the 12V swap will give plenty of potential for further improvements in airflow should and issues arise with higher road speeds. most of the tests i was between 45 and a top of 60, the car gets a bit wild at 60 on the B roads, more akin to sailing than driving. I was thinking about dual speed in the future but ill need to look into it abit more for the correct fans and stuff.

Excellent work with this one, you'll crack it in the end - hopefully with this! Full 12v conversion on the cards? Yeah thats the plan, I love the fact its 6v but after seeing how much airflow i get and how quick it drops temp with a 12v fan it has to be done. Just waiting on a 12v alternator to turn up and i can work on the wiring side of things.

All plumbed in in a fashion as I'm not going to mad with making it neat and tidy yet until its all proved itself. Ran it all up and it seems good at idle, i wired the new fan to a 12v battery and fair play it moves some serious air in comparison to the "6v" fan. I will try and get the radiator totally paneled off again this eve/weekend and maybe do a quick test with the rad fan running off an independent 12v car battery (as suggested above) and see how it behaves. If it works well it can all stay in place and be tidied up if not i can look to moving everything up front.

Scrap yard raid this morning for a selection of hoses, a header tank that might work and a fan and I came away with a radiator too. It was a calsonic item who I've heard off from my early gran turismo days so should be a good brand? slightly smaller than the new rad I have but also a different style core. It has a take off for self bleeding too which will help with trapped air issues. I've also measured its water volume at just under 1600ml or 1.6 litres (200cc more than the original dauphine rad an 600 more than the new rad). Next job is to get it fitted up and fingers crossed an alternator will appear soon to run it all. The fan though smaller is a curved oem style fan so I'm hopeful itll do a better job than what I have. So to surmise I have a smaller rad and fan 🤷🏻♂️🤦🏻♂️ but hopefully a better rad and fan with more water volume.

all out the window with covid. 6am till 9pm and 7 days a week so I'm told. only an issue if people complain but then the complaints process is long winded. fill out time and date logs even though videos were sent showing it happening. theres a long list of complaints from lots of people now but the local council don't seem to care tbh. they will be gone soon I hope.

I'm pretty sure they have yes. Feud with some local builders popping up 9 houses behind mine. I'm the moaning neighbour who thinks its unreasonable for them to be blaring music and singing at the top of their lungs at 6.30am. Weve had a fair few run ins now and alot of people are starting to complain but I'm quite vocal and will just walk on site and tell them, I'm also right next to them and my garage and driveway is at the site entrance. Other than them i cant think who would want to or who would know that messing the order on the dizzy cap would effect running.

No the old rad sprang a leak so that's when i replaced it. It also doesn't have the hose connections in a place that would work well with the engine setup. Tops and bottom hoses were on different sides and differing top and bottom.
Agree though 400cc less radiator capacity and less airflow through the radiator with no fixed fan.
The radiator i have is from Eurocarparts made by EIS? I've looked at the rad fans in pics and the radiators they are attached to look a lot better construction, more brazed looking than tube and fin. When i get down the scrap yard, if the rads look like a better construction or just better quality i will swipe the whole assembly and fit that in there too after measuring water volume.
Today's small amount of work included refitting the exhaust, setting the valve clearances which needed loads of adjustment strangely and cranking it over. When i refitted the head i though the pushrods were abit slack but didn't think much of it. When i came to start it it was back firing and throwing flames out of the carb. Strange, so i reset the clearances, i think i have a thinner gasket on now as they took a fair amount of taking up. Car still wouldn't start and was behaving the same. For some reason some one had mixed up the HT leads, I have an idea of who it would of been but i may have to get a camera out on the garage soon. I never removed the leads from the dizzy and left them all in place, the leads also have spark plug numbers on them.... Anyway once id put them on correctly it caught and fired up nicely, turned it off promptly as there are no hoses or rad fitted but good to know its ready to run.
