Coolant flush
Hi All...
My 2004 Discovery (127.000 miles) needs a coolant flush. Can anyone tell me the best way to do this?
Is there a drain plug on the bottom of the radiator?
What type of coolant is best to use?
How much of coolant should be used?
Please help...
Thank you

Conventional antifreeze is not the right fluid to use. Not sure about the 50/50 mix? That would mean 50% water is on your aluminum head. The dealer has recommended using 100% XLC but you can use 50/50 if it's distilled water.
This applys to most 1990 and after models, unless you have the Range Rover 2003-2005 with BMW engine (which uses a special blue mix). If your vehicle already has green DO NOT MIX WITH XLC ORANGE it creates a gel that can ruin the motor. Make sure to flush the whole system before switching to the correct anti-freeze.

Take a look at the product data sheet. They do not give stats for 100% XLC. It starts at 50% and goes down. They also recommend a min of 33 vol. % of XLC and no more than 70% in the coolant solution.

I used Peak Global Lifetime. PEAK | GLOBAL LIFETIME 50/50 | Antifreeze / Coolants | Auto Products
I used the full strength not the 50/50 premix and diluted down to 50/50.

You never want to use 100% coolant. It needs to be mixed with water to get the best freeze protection. Coolant also transfers heat slower than water. A 50/50 mix is the middle ground for good freeze protection and heat transfer.

This seems more challenging than I thought ahha. I am getting different answers. All I wanted to do is go to Auto Zone, pick up some coolant and fill it up. No mixing, diluting, etc...

There is no drain plug however if you remove the lower LH side (drivers side) waterpump bolt (11mm head) it will drain 75% of the coolant . Then remove plug in LH rear of block (square head) to drain down to 90%. Pulling the lower hose drains well but blows coolant all over making a helluva mess. Use a 50/50 mix of XLC to refill

and that is all you need to do, dump the old stuff by pulling the lower radiator hose and replace it with 50/50 green coolant
