Coolant Draining?

[mattc]

Just wondering where is the best place to drain some coolant out of my IS200? I need to top up with some anti-freeze, but unsure best way to drain some fluid off.

A pic or two would be good.

Thanks in advance

There's a drain tap on the bottom corner of the radiator- undo this to drain the old coolant.

Is that on the bottom right when looking at the front of the car?

Can it be accessed easy enough without removing anything from the car?

Can I get to it from underneath?

im sure you can get from underneath car not sue tho...

Yep- bottom right when looking straight at the car.

You may have to remove the bottom engine cover?

There is actually a hole in the bottom engine cover under the tap, which I noticed after I removed it!!! At least removing the cover made it easier to get to the tap handle to open it anyway...

I just replaced the coolant in my IS200 today.

1. jack the car up and remove engine underbody tray #1

2. After ensuring the coolant is not hot, remove the the radiator cap and loosen the drain plug at the bottom corner of the radiator.

3. Loosen the small hose connected to the radiator cap and swing it down to drain out the reservoir.

4. Locate the drain plug on the engine. This bit is very difficult to see and can only be accessed from beneath the car (hence why you need to remove that underbody tray!). The engine drain plug is situated to the right of the oil filter. Connect a 1m length of hose to the nipple of the plug. Using a ratchet wrench and a 10mm socket, loosen the bolt to let the coolant out.

5. Tighten all the drain plugs + loosened hose.

6. Refill with new coolant.

7. With the car on an incline (facing UPHILL), start the engine with the radiator cap removed to let out any air stuck in the system. Fasten the cap when that's finished and you're done!

Remember to keep an eye on the temperature gauge and any coolant leaks.

Nice write up mate. Well done and thanks.
