I only use honda coolant. My 2003 crv has almost 300k on the original water pump.
Use the OEM honda stuff. It's really nice.
I'm running Honda type 2 coolant in my 94 sonoma. Flushing helped but it seems getting a good P-HOAT coolant stopped or at least paused the rusting while offering better protection.
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.
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.
You want the very best you gotta go Honda blue.
Nothin better than that OEM Honda
Toyota coolant, the red / pink stuff is some of the best coolant available.
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.
