Heater wasnt working so I decided to replace the T-stat and flush the coolant while I was at it. I am also going to make sure the T joint at the top has the proper restrictor, but thats another story.
I pulled the coolant surge tank and it was filthy, so im cleaning it. But when i pulled the hose off the thermostat you could see the rust build up everywhere and the coolant looked real bad, like brown water. I know the coolant tabs turn it brown, but this had no viscosity at all and i saw some black specs in the coolant so I imagine it hasnt been well maintained.
I loosened the radiator drain plug and it started to drip, very weak drip at that. I then pulled the screw and washer out and it didnt increase the flow. Does it sound like the drain is clogged? I looked at the FSM and they show 3 parts of the plug, Is the part labeled "body" supposed to come out aswell?
I really just want to know if its clogged, and if so how would you go about cleaning it?
Ran some radiator cleaner through it and flushed the radiator by adding water through the fill neck and forcing it out the upper hose hole. The drain is now working much better. When I fill with straight water and run the engine up to operating temp and drain it the water comes out clear now as opposed to brownish tint like before.
Guess its time to fill it with coolant/water/bars leak and seal it up
