So you’ve installed your new mk4 powerplant into your mk1, now you are left with plumbing it in. Some swaps (vr6 specifically, the TDIs dont fit well either.) require you to modify the radiator, and finding stock hoses that will work can be a scavenge-fest.
We have used a stock mk1 rabbit radiator flipped upside down, then you have to cap the overflow port, and it wants to leak eventually, not to mention that your temp switch is now across the engine bay and in the way of everything you just installed..
Soo… we went looking for OEM options, found a dasher radiator that works pretty well, unfortunately the aftermarket support for Dashers is very small. There seems to be little to no stock of the replacement dasher radiators anymore. Leading us to our natural course of action, make something that works the way we want.
In about 1-2 months, we will be stocked with a new radiator for your swaps. Fully tig welded endtanks, no plastic all aluminum construction coupled with the dual pass design will help keep your rabbit running cool. Stock mounting pins and core-support mounting tabs are in place. We also have removed the overflow port as most mk4 based swaps have a port on the motor or in the factory hoses.
These will also work for those who want to run carbs or ITBS and are using some sort of an overflow container.
