What coolant to use?!

[jacobm24]

I have a 2000 f250 with 46k and it is due for a coolant change but i am completely lost on which to put in. It has green in it but I see people with gold and red. Should i switch or stick with green and keep an eye on it?

I'm going to answer your question like this: I'm going to do mine in 3-4k miles, and I'm going to do new hoses, Billet T-Stat Housing, a 203* TS, and a coolant filter. Then I'm going to use ELC (Red) with the CAT HD Diesel rating. But thats me...

ELC coolant, CAT EC1 rated.... best for your truck and any diesel.. just flush it well before changing..

An Extra, EXTRA, good flush!

Remaining silica based coolant (green) can react with the ELC and form jelly clots that can clog things.

ELC is better, but, there's nothing wrong with properly maintained green either.....

Personally, I just stick with whatever it came with. Plus, you know that ELC is gonna cost you $100

I spent over 100 bucks changing and six hours. I used the restore and ran out of distilled water after 30 gallons and had to use hose water to get the PH level right. My delta's were around ten so I didn't think I had a choice. I watched my oil temp and they quickly come down. I need to still get a filter in my coolant system.

Stick with the green and get a good quality and you'll be fine. I change my coolant about every 2 years still test good but hey its a piece of mind and alot cheaper than corosion probloems.

I used CAT ELC in my 7.3 for many years with no issues. But honestly, if I was you I would just get some fresh green coolant from Ford and go with that. It requires more upkeep and won't last as long but that isn't too big of deal, doesn't look like you put very many miles on your truck anyway.

Has anyone done a writeup on which green coolants to use by brand? Does it have to come from Ford, or is something like Zerex safe to use? Inquiring minds want to know!

lol. i just got the truck off of my grandpa and he only drive it once a week! it was a steal. in two weeks though I've already put 1200 miles on.

What im kind of getting at is just getting green zerex and change it every two years? (not a hassle for me) I dont mind paying extra for good quality. Is zerex good stuff?

ELC all the way, no questions asked on that one. Spend the time and the money. It will cost you more than 100. Figure when you flush, use a product like Restore and Restore plus or Fords VC 9.

Dood, holy low miles! NICE!
