Ok I have a 94 4.0 w/ AW4 tranny and 231 tc. It has 128000 miles on her. I need to have the cooling system flushed as it has been close to 3 years for it. I put only 16000 miles on her in that time. I have a new thermostat and gasket and a new lower radiator hose for it. I'm having the flush done being it's only 40.00 bucks and the mess is not in my garage. What I'm wondering is do I change the thermostat and lower hose before or after the flush and fill? As the coolant is dirty and I guess I'm concerned of the thermostat plugging up during the flush. Should I add a chemical flush to it before I go get the standard flush? Do I add a water pump lubricant after all this? Thanks for the help and opinions.
