I have a Honda 2003 Integra dc5 and I'm looking to replace the coolant, (it's low and I don't know which specific coolant is currently in it)
I'm based in Australia, and I have easy access to car part stores like Supercheapauto, Repco, and other equivalent stores.
The problem is that the online shops are going to cost alot for the Honda type 2 coolant in both shipping and the coolant itself or other equivalents that are seemingly American.
So after looking around for a while, I figured out that the K20A3 uses a Phosphate based coolant and silicates will damage the engine (correct if I'm wrong), but the other problem is that "correct ones" according to coolant manufacturers don't have Phosphates or have silicates, I.e. Nulon and penrite Green, which is hybrid-OAT but don't state if it has Phosphates or silicates, the blues are OAT but no silicate or phosphate, the Penrite Pink is a P-OAT coolant, which the k20a3 uses much more, and my current coolant is a green, which could be a H-OAT, a H-OAT that's Phosphates, nitrite and amine free (silicates not mentioned), or a "type B Hybrid Additive technology (H.A.T)" coolant which says very little.
I feel like I'm losing my mind for being so specific, but I wanna make sure my car is going to last, so I wanna take care of it but AI, oem purists and conflicting anecdotal reports are getting me confused.
Can anyone gimme an idea of coolant I should be looking out for? Phosphates? Hybrid Oat or Oat is fine?
