I would use either OEM Honda Anti-freeze or Preston makes a fluid for Hondas.( Walmart carries it) OEM fluid in about the same price as the off-brand.Outside of this, it’s not worth the risk.My 2006 ridgeline is new to me. i have a radiator leak and am about to replace it. The fluid leaking is green thats all I know about it.
Can I use a good non silicate coolant for aluminum engines without gumming things up ?
I would recommend giving it to a shop for troubleshooting. I did the best I could do in my driveway with off the shelf parts and all pointed to a bad compressor. Turned out it was just improper refrigerant amount. One of the best values of $150 I spent.I did the repair already .... Did inspect all my hoses and clamps all in good condition. Everything is operating beautifully. I may do the flush and fill later with honda coolant. Thanks again ! .... On another note I have been having ac problems .. Used a uv dye no leak to be seen not behind the glove box no where at all !!! I can only think its my compressor. I have hissing if I put refrigerant in the system but no visable dye. Possibly internal valve in the compressor ? .. Any ideas would be appreciated ! ?
