How do I flush my radiator?
Well, I've got my radiator out of my truck to take to my friends shop and have it serviced and repaired. Also got me a new thermostat. What is the proper way to flush the engine? My truck is a 78 with a 460. Thank you in advance.

One way you can do this is by sticking a garden hose into the upper radiator hose inlet (make sure you remove the thermostat first) and turn your hose on and run it untill the water is clear... I wouldn't use any chemicals in your coolant system because they can cause leaks.. I would just run some water through the engine block untill it runs clear that should work just fine

Thanks mark a.. I just crawled out from under my truck to check on the freeze plug accessibility after reading your post and I found a leaking rear freeze plug. Nice. These things look kinda tough to get to. I don't feel good about just replacing the one. I'd like to replace all of them. Can this be done in the truck or do I need to pull the engine? I've seen brass plugs as well, should I go with those?
