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.
You want the very best you gotta go Honda blue.
Nothin better than that OEM Honda
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’ve never ever seen OEM Honda coolant even remotely dirty, sludged or have insufficient protection even after 100k miles.
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.
