Intercooler & Radiator Manufacturers: Link

I found the optimal intercooler for my T3 there. It takes a little searching, but all the intercoolers are listed with diagrams.

It would be great if you could let us know what fit best in your T3 and how much it cost .

Hi,

I found an old post about that.

Finished products with TÜV certification are simply expensive. There's still one available from Busschmiede.de, but it also costs 1400.
You can also put something together yourself. You'll need a water cooler from a Fiat Cinquecento 1100, a liquid-liquid heat exchanger from Peugeot/Citroen, a circulation pump, an expansion tank, and hoses. And that's how you create a water-cooled liquid-liquid heat exchanger.

Best regards,

I'll definitely stick with air-cooled engines. I've already started experimenting with some metalwork on a 'battle bus' (likely a heavily modified vehicle).
By the way, my intercooler replacement cost a total of 180 euros. Anyone who pays more than 400 euros is only to blame.
