If I'm filling the system up from being completely dry, how much 50/50 mix coolant do I need?

I believe it takes 8 gal

 

When getting ELC OAT coolant, does it say "OAT" anywhere on the bottle?

Drake

 

It should be on the jug some where, might be on the back

I got the Cat stuff & do remember reading the OAT on there

 

It might on the back somewhere, but just look for the Cat EC-1 compliance in conjunction with "Extended Life Coolant" print on the bottle.

Some brands will also say on the bottle "SCA not necessary"

Chevron Delo ELC looks like this:

I have used Evans on one of my turbo charged track cars. It has some benefits on cars whose coolant systems are "challenged" to keep up with extreme situations since it doesn't boil and can be run at 0 pressure. Overall, I don't think its worth it for a PSD. The coolant system on these trucks seems to work well.

I did blow a hose once on that car while using Evans. I made an emergency repair to the hose and topped off with distilled water to make it home. Flushed it all out after that and went with cheaper, readily available distilled water and coolant.

 

Wow! Thanks for all the very timely info, especially the link to the coolant info. Almost too much. I am thinking of a coolant change this weekend. It has very green coolant.
So, I bought my truck with 191k, has 203 now. Previous owner had for 50k, 5 years. He did not remember doing the water pump.
How would I know if it has been changed, and what is the recommended change interval?

Thanks.
Tom.

 

I just replaced the water pump on my 02' 7.3 last week. I made the switch to Evans NPG+. I bought another radiator cap and gutted the internals to make it zero pressure. I wish someone would make a low-pressure cap the the 7.3. I'd like to have a little pressure, maybe 2 psi.

The motor has 280,000 on it. I'll report back if there's any problems.

 

Just a followup, I had to replace the water pump again this week. 299,000 on the odometer. So a new NAPA water pump only lasted 19,000 miles.

Maybe the zero pressure cap had something to do with it, not pushing coolant far enough into the assembly.

 

Interesting

 

While I know the cause of the pump failure could be a few different things, it is anecdotal evidence such as this post, that caused me to post what I wrote in post #2 above.

I am not a fan of NAPA but i do buy my ELC diesel coolant (Zerex) from them.

 

I've been using Evans for a couple years now and it works. Coolant is as clean as it was out of the bottle. It is Not a zero pressure system. I've asked Evans about this and was told to run the stock cap. You CAN run no pressure as it has a higher boiling temp than water, and that may be an advantage for some applications. I bought a 5.00 cap and drilled a hole in it and ran that for a while to get the remaining water out and then put on the stock cap. I like it. No water, no rust, and is supposed to reduce cavitation. In the end, just use the best product available.
