Antifreeze Pentosin or OEM Toyota

Pentosin Pentofrost

I use the blue antifreeze (G11) that was specified for my 1987 16V. I am currently running 10W40 synthetic oil.

I use Pentofrost (Pentosin is the OEM supplier to Porsche). Our local NAPA carries it even.

Pentosin is one of my trusted brands. I would not hesitate to use it.

My last vehicle was an RX350 which I had for 14 years with 115,000 miles before trading it in and had zero leaks. I flushed/replaced the coolant at 100,000.

I've used pentosin E for full flushes of two Golfs (2015 and 2017). No issues. Prior to that, I used it for topping off. It's the right stuf being G13 regardless of slight color variation pink/purple.

Proton original radiator is of very poor quality. Rust prone. Change it as soon and use premixed Toyota Coolant bought from Toyota Service Center to avoid fakes. Toyota SLLC and an aftermarket radiator will last the remaining lifetime of your Saga.

Pink colored Toyota Coolant. My friend is a former mechanic and he recommended this over Honda's.

Mods: None, staying showroom stock. TCL Buyers Guide Negatives / future ownership issues: A) Valley Plate coolant leak: Look for pink crystals (dried coolant) underside of engine near where transmission meets up w engine. Also check upper radiator hose where it connects to radiator. Workaround: 50k/5 year coolant maintenance.

I used 3 of those Pentosin blue with a bottle of Water Wetter and the rest is water.. my temp is 30 degree higher than it was before and I don't know what the heck it was in there before which is this yellow/green milky stuff, it sure kept the engine mostly below 180. But now I hit 220-230 easily
