unfortunately you need a cooler for a water-cooled car. i've chosen a cooler from a golf. it's placed in the front instead of the spare wheel. what you see are two alloy sheets to cover the cooler. they also guarantee the correct air flow through the cooler. you also need efficient oil cooling. i've build a ventilated oil cooler in the back under the right wing. the ventilator is under the wing in a tube. the cooler fits under the engine hood  i will put more pics in the future on this page
