If you want to do the coolant change and make sure your cooling is tip top. Pull the radiator ( not a real fun job) then get it rodded out while there have them install two drain cocks near the inlets. From what I see you have a modern core if not and something is wrong your up for $$$. Time to install two new water pumps, drakes or skips you choose, or you can go through yours. Install with stainless bolts. Also I have fitted those cone shaped filters that will trap a fair bit of crap in the top of the radiator hoses. When it comes to flushing you can simply take out your thermostats bolt up again stick a hose in the top open the drain cocks and flush through. When cool drain again blow out as much with a compressor , reinstall thermostats , drain cocks, clean out the cone filters fill up with distilled water and I prefer a non glycol type coolant. Bobs your aunty!
