Antifreeze OEM Toyota or OEM Honda

Just use toyota long life coolant je bro. Applicable to all car but buy the original one at toyota SC. Many prefered this coolant since it is good to engine cooling system

I have looked at the additive packages on all Honda compatible coolants. Many other manufacturers (Toyota, Ford, Hyundai, Mazda, Subaru) have switched to similar coolants that are slightly worse than Honda coolant. Honda has the strictest requirements for their engines that they refused to give their engines to GM for Saturn cars after GM said they will require GM coolant. Here are my rankings:

1) Honda Type 2 (OEM) Coolant Best OEM coolant Has about the same Diethylene Glycol and anti corrosion and detergent additives

I currently just drove 20hrs down south to Florida and the engine level has stayed slightly below half level as it should be the entire trip. Still in Florida driving around the intense heat and sun and everything is still going well.

I’ve never ever seen OEM Honda coolant even remotely dirty, sludged or have insufficient protection even after 100k miles.

for choosing coolant, if just topping off, i use whatever's already inside. so if it's factory coolant, use Toyota OEM coolant.

For Coolant OEM Honda the blue stuff is perfect it's almost like it's made for the car.

The correct coolant is Honda longlife which is blue. Someone has already put \"all vehicle\" green stuff in it, which will keep it cool just fine but not provide as much corrosion protection over the long term. The factory Honda coolant is designed to run for 120,000 miles; this stuff is good for maybe 30-50k before it should be changed.

Mine went 11 years with not as much as a check and it came out perfectly the same as the new stuff going in.

The green does "work" but it wont help the health of the engine long term as there are chemicals in the Toyota red which help protect the engine, fittings, rad etc. Buy the right stuff from Toyota and it'll last ages, the wrong stuff will screw things up long term.

You can add distilled water as a temporary option if you can't find Toyota pink coolant.
