Anyone know?

 

I'm pretty sure there's a drain plug on the bottom tank of the radiator, that's where it is on my Soarer, however I'm sure that all Soarer V8/SC400s have the same radiator set up.

 

theres a little drain **** you open up and take the radiator cap off the top so you have some flow

thats the easy way, you wont drain all the coolant, if your car has been well maintained I really wouldnt worry about draining the coolant from the block as well

when you fill it up, I usually run the engine with the radiator cap off and try to bleed as much air out of the system as possible and for the next few times you drive the car, whn the cars cold open up the radiator cap and fill it up to the radiator neck

 

Anyone know the price of draining the coolant at the shop? I would bring my own anti-freeze to save some costs...

 

expensive.
