Hey everybody,
So after an arduous few weeks of burning the candle at both ends, working 10-12 hour days, prepping my house to go on the market, waiting for parts and fighting daylight, I've finally completed the install portion of my repairs. Today I began the process of flushing the cooling system and have some questions about how to proceed. I have replaced the entire cooling system with exception of the radiator. Because it appears to be brand new or very close to it. Today I pulled the block drain and knock sensor and hooked up the prestone flush and fill kit. I ran clear hoses from the radiator drain and block drains into an extra large catch jug to avoid the mess and so I could see when the water ran clear. I turned on the hose and flushed until I saw the water run clear. I did not run the engine during this process. I then took the garden hose and ran it directly into the radiator fill neck and let it run for a few minutes, for good measure. Since the only things that really need flushing at this point are the radiator and manifold. Everything else is new. I was considering pulling the thermostat and flushing directly through the manifold too. The previous owner was running green coolant in the truck and per the advice I got here, I'm switching to dexcool. I also picked up some prestone flush and cleaner. I was planning on doing that next and then flushing one last time with water. Also, I have already removed and thoroughly rinsed the coolant reservoir. Will this be sufficient to ensure all the old green coolant is out of the system? Is the prestone flush chemical safe to use on our trucks? Or should I skip that step? Is there anything I'm missing or anything I should do differently? I really just want to get this right the first time and get my baby back on the road! Any help suggestions and information are greatly appreciated. Thank you in advance.
