I want to change my coolant but I'm seein a bunch of different ways, like the drain plugs on the block, the plug on the bottom of the rad, or just pulling the lower rad hose.
What's the best way to change the coolant? I'm not going to buy any of that flush stuff. Just wanna change it Thanks!

The way I've done it in the past is to take the radiator cap off, detach the lower radiator hose, and open the radiator plug on the bottom. Then I bought a new thermostat and refilled the system with 50/50. Once I had it filled up, I would leave the radiator cap off and startup the engine. This will let you know the Tstat has opened and let the fluid run through the entire system. Then you can slap the cap back on there and fill the radiator and overflow tank properly.

Check your user manual, or a Chilton's book for the amount and type you need. There was a switch at some point to a different type somewhere in the 90's.

This process is not a radiator (and system) flush, but it will replace like 85% of the fluid. Maybe the Chilton's would have the process for a full system flush.

The proper way to bleed the system on the V6's

Open the breather vent in front of the intake (you'll see the pipe coming off water pump and going up and back towards the back of the car)

Fill from radiator till it stops dropping

Cap it off

Continue filling from the breather vent till its full

Cap it off, refill overflow tank if not already done

Run the car till it's at normal operating temp then shut it off

Let the car cool off completely and refill whatever coolant was sucked out of the overflow tank

This is all you ever have to do and 99% of the time you won't have to re-bleed it..
