Engine radiator VALEO or OEM Volkswagen

In the year I’ve had it, it’s cost me a new radiator that had split.

Didn\u2019t take many pics but I installed a new thermostat, radiator, upper and lower hoses today.

I used a like new radiator I had from my 16v post going aluminum rad and fans on that car. so new fan, cleaned up the wiring and put a better looking relay in and tested it.

My NA 1.4 OE failed (long time ago) because of aluminium tubing corrosion (brine). So replacement Valeo got paint treatment . So far 100k km without problems.

I remember when my First Radiator blew up at 20108 miles, just out of warranty, and the Dealer ship was going to sell me another Plastic/Aluminum one for the mark down price of 120 bucks. I found a radiator shop that got me a Brass and Copper one for 108. It lasted for the next 19 years with out failure.

I replaced my radiator several times, always due to corrosion at the bottom edge where brine accumulates. Last time I replaced it for Valeo and for sure it had same design as your "new", which is a stamped aluminium sheets stuck on cylindrical piping. So far so good.

Right now I've got a 2015 Polo GTI 7 speed. It's got about 100,000ks, I'm the second owner. In the year or so since I've had it, apart from normal things like brake pads, I've replaced: Radiator

The radiator on my 2016 is leaking, although leak isn't really the right word. Maybe porous. The hole is so small, it takes months to show a change in the coolant reservoir. On some days, given proper conditions, a small wisp of steam is visible coming from the radiator area. I added a UV dye to the cooling system, and it is visible then.

I was using Valeo radiator for 1-2 years, then it blew hole right under the hose connector.

This new radiator expect to fail within 1 year warranty or 1 day after warranty runs out. Original OEM was Valeo Made in Brazil, went 22 years. It cracked from pulling on upper hose to see timing mark on flywheel.
