You-Tubed changing the coolant with a full flush and only got about a gallon to drain into the catch bucket. Do I have to pull the drain plug from the engine block to make sure of a full purge? And if so, how to I get too it? Does all the sound trim underneath have to come off? I had to put the front end up on ramps to get my petite body underneath to get to the drain plug, but the drain plug would still be the low spot even if it's up less than a foot. Thanks, Chilton is not very forthcoming on how to get this done.

In the diagrams down below I have included the coolant and capacities for your vehicle as well as the instructions for flushing your cooling system from the vehicle manufacturer.

Hello again.

To answer DAN5594; you wouldn't want to use white vinegar due to it being acidic. Any foreign debris or acidic compounds introduced into the system will not only ruin the radiator and hoses but will cause damage.Just do a cooling system flush with auto parts store products or just simple water flush.Hope this helps and thanks again for using 2CarPros.
