Whats the best coolant to use thats easily found in local auto parts stores? With or without adding sca
My advice use the prestone with core guard concentrated and then add distilled water to it also I suggest add a coolant filter on your heater feed line reason being can buy coolant filters with the SCA already in them for cheap and a coolant filter gets rid of any trash in the system this helps to avoid cavitation as any trash / dirt / rust and such will work as an abrassive on the cylinder walls add cavitation issues our motors have well this covers you from all directions do not use the extended life coolants in our engines its asking for problems as they are more acidic or base depending on the brand we need a neutral coolant PH and prestone with core guard is one of best ones out there I have found for the money.
nope its standard green coolant without any precharge prestone with core guard is regular coolant with more anti corrosive additives and also a better PH stabilizing additive compared to other green coolants be carefull most of the odd colored coolants aka non green coolants are hybrid organic acid technology and not organic acid technology ours need the regular organic acid technology coolants otherwise it causes issues with our gaskets aka head gaskets and intake gaskets and such the prestone with core guard is best all around coolant I have found for our motors then add the motorcraft VC8 coolant additive or add a addon coolant filter with precharge.Is that the purple coolant? I see O Reilly's list it, but they don't keep it in all the stores. It is SCA pre-charged.
I have been using the Zerex GO5 ever since I went to the champion radiator. That has been 15 years now, I posted in another thread that the radiator just sprung a leak, so I am buying another one. I am being careful and trying to save what GO5 I have and then add new, it's almost $20 per gallon.
I know what the original poster is getting at, you need something that works and is easy to get. The GO5 fills that bill. If it's good enough for Mercedes Benz diesels and also newer Ford diesels, it's good enough for me and my old truck. It's supposed to inhibit liner corrosion and pitting.
