Engine radiator MISHIMOTO or OEM Volkswagen

EDIT: SOLVED - noticed no leakage around thermostat, coolant ball, all belts were dry, and upper radiator dry. In the end it was the radiator.

run a mk4 secondary rad.

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.

90 16v Passat rad fit just fine in my mk1 Jetta with a single fan mk1 (which mounted to the rad just fine) you can cut the wires and set them up for how ever you like.

Looks like overall fitment of the Mishimoto radiator was clean and straight.

The inline Moroso filler neck will be welded to my Mishimoto radiator

mishimoto makes a great aluminum replacement at a decent cost.

been using the conditioner for years without issue, although it didn't prevent my HG's from leaking eventually.

Stay away from Mishi. That is certified garbage juice.

i've never really heard good things about mishimoto's fitment and for 500 bucks you could find better mods to do.
