it is located coming out of the firewall lower passenger side it is a black hose that is kinda hard to see and get to if you have a something about 2 3 feet long you can reach it and knock it around and it will unplug it
Under the housing where the lower radiator hose attaches.
I have a sportster and it doesn't have a drain plug. It has a drain hose that is located under the engine and is connected to the rear pipe mount on a stud with a small hose clamp. Loosen the hose clamp and just pull the hose off the stud and the oil will drain. Don't forget when replacing the oil to put about 4 oz into the filter before putting it on and make sure the oil starts to come out of the drain hose before reconnecting it to the stud or the oil will get vacumed similar to vapor lock. Hope this helps.
The best way to drain any radiator is to remove the lower radiator hose from the block and/or radiator. Compress the spring clamp located on either end of the lower hose and pull back about three inches. After doing so you will be able to remove the hose from its inlet. Im not sure that there is even a drain cock for the 98 - 03 Chrysler Concorde.
it helps if there is a year? but its on the right side of the engine if you follow the big black hose from the radiator to the engine its right there by the engine inside the hose! that is for a 99 to 03
In the fuel tank
i think its 0.042
On the steering wheel by the airbag
Premium is ok
The drain plug on my 06 vinson is 17mm, I would guess they haven't changed since 03. Hope this helps.
Its located in the power distribution box under the hood in cavity number 60.............
It's pretty easy. Drain it, pop off the outlet hose and the power supply quick disconnect on the top then the whole unit pops out of the tank like a cork. A flathead screwdriver should do the trick.
its 9/16's
