Well yesterday I accidently poured some green coolant into my truck that has dexcool in it. I only poured a little over half a jug of premix into the reservoir. I have not started the truck since I did this. Will I be ok if I just drain the radiator and tank from the lower radiator hose and refill or do I need to do a complete flush? The truck has a slow coolant leak so I don't want to have to flush it now then again when I fix the leak if I dont have to.
