cat ec-1 coolant premixed

[ktb66062]

Is it ok to use the cat brand elc that is premixed. It's all the cat dealer in town has in stock. They said it was mixed with distilled water but I don't know if they have a clue. The kenworth dealer in town also said they only use the premix and its all they stock. I know this is really important. Is it safe to use the premixed?

IF you use pre-mix after a flush with the water that remains in the block (That you cant get out) you will have less than a 50/50 mix. I would try to find concentrate. My local NAPA carries the Zerex ZXED1 (Concentrate). Maybe the could order it.

The local cat dealer said they can get the concentrate, but all they had on the shelf was premix. For me it was ok as the guy that did my heads and oil cooler drained/vacuumed all the water out and installed the premix. I just bought a gallon to have for top off.

I see. I didn't think about water being left in there and being less than a 50/50 mix. They said they can order it.

The block retains very close to 50% of the total cooling system capacity, even if you use both of the drain plugs. Using premix only will net you 25% concentration.
You definitely need the concentrate.

I had the same problem, all my Cat dealer could get was the 50/50 too. Then I did like 4x4ff said and just got Zerex at Napa. Works just fine.

How much is the zerex? The cat full strength is like 21 a gallon

dang, i used the premix, i didnt realize so much was left in block, i did pull the eng block plugs...... guess is should get some concentrate... im never in freezing temps living in Vegas, is there any downside in cooling effect having less then 50/50? i have always heard nothing beats just water for cooling....?

I was quoted $17.99 per gallon for zerex at NAPA. Cat wat $24 full strength at the cat dealer.

I'm really suprised y'all's CAT dealers don't have ELC concentrate on-hand.... mine had 40 gallons. lmao
