Best Engine radiator for Volkswagen Golf

I had a similar issue with my Mk4 VR6 Golf, coolant level would drop a tiny bit over time with no obvious sign of leakage..turned out to be a very small leak at the bottom corner seam of the radiator.

run a mk4 secondary rad.

Im going to be replacing my radiator soon with all coolant connection and hoses, does anyone know the difference between the radiator std and heavy duty one? STD: Nissens #652011 Heavy duty: Nissens #65011

I will will just add that I have a 2L 16V running no oil cooler and an early Mk1 radiator with built-in overflow tank, two pin thermostat, short 5th gear, and the car does fine in a traffic jam and with spirited driving.

No worries with the nissen branded radiator. I have installed tons of them into mk3 vr6 cars over the years with no issues. They fit perfect and the quality is very good. I have a mk3 fitment nissens branded radiator in my a2vr6 also that I installed a few years ago. It cools the car perfectly fine on both the street and the drag strip.

i have a mishimoto radiator and it works just fine :thumbup:

I traded my mk8 GTI (early Canadian model) for a mk7.5R recently because my mk8 GTI was so problematic: the rad fell out at speed and left me stranded (this should no longer be an issue on these cars)

2012 Golf R (FSI) and just recently had a Mishimoto radiator installed. Car behaves normally on the road but the first track event after having it installed it got very warm (about halfway between normal and red zone on factory gauge) and actually spit out some coolant under the hood I found once back in the paddock. Shop has checked everything out, re-bled the system and found no air but does start to get hot under sustained boost. Funny thing is I track the car heavily and never had this issue on the OEM radiator, also the water pump was recently changed with timing service and has less than 1000 miles on it.
