Talked with my international dealer and they only sell 50/50 Chevron ELC so i gues that is what i am going to get anbody used this.

 

Try get undiluted as you can't get all the water out of block and system after flushing. You won't be able to get correct coolant water ratio. I put in 3.5 gal of concentrate prestone heavy duty and it has to be CAT EC 1 rated. Might not have the cat designation code right but someone will correct. Picked mine up at carquest.

Yea i was looking for somthing not 50/50 and international store thought tht it was funny that i did not want the 50/50.

 

Not really uncommon as they are likely interested in the sell aspect. If you decide on an ELC, please ensure a good flush of your system is performed. You want the "gold stuff" out of their first. With concentrate usage, most knowledgeable folks will tell you to use distilled water to get your mix right and I agree. I used the distilled water with a flush agent to clean my system. When finished I put 4 gals. of rotella in and completed filling with distilled water.

 

Yea I was going to flush with restor and diesteled water a feature times before I went to ELC.
