coolant question/help please

i recently replaced my water pump a month ago/500 miles ago. my truck had green coolant in it i dont know what brand. i know my truck like the back of my hand and all fluids it requires except coolant. i know very little about it. after i did the water pump i filled it back up with my local part store brand coolant (i was in a rush). it was 50/50 mix and it says low silicate formula but it is ethylene glycol base

i heard the eg base coolant cant be used in our trucks. do i have to replace the coolant or am i ok with this stuff. it is low silicate formula.

If you want to do your truck a favour, flush that crap out with a good flush system and refill it with ELC (red) coolant.

Otherwise, get some Fleetguard coolant test strips and make sure your levels are balanced.

Do a full flush. There is a product called Restore that will remove all the crap from your green coolant. Also, go to Ford and get 2 qts of VC9 from Ford to clean the iron scale.

Flush with a lot of water until clear after all chemical flushes. Then flush a few times with distiled water. Then get yourself ELC Concentrate (never 50/50) and fill.

Coolant basics:
On ALL MOTOR flushes, dont use 50/50. It can be used for topping off. You will NEVER get all the water from your distiled flush out. I dont know the EXACT amount of water left behind in a 7.3. I do for the 6.0 and 6.4. So, if you do know that you can get a perfect 50/50 mix.

On a diesel motor, you want to use an ELC. Silicates from typical GL coolant will do dammage

Get yourself a coolant filter. All diesel motors should have one. Why light trucks didnt get them is beyond me.


I understand your truck came with the green stuff but they figured out it isnt the bvest choice for our diesel motors. Green to red, never yellow or orange.

Cheers,

Zrain: Check your green coolant info that you just poured in... If it is ethylene glycol-diethylene glycol--{Sodium 2-ethyl hexanoate} ? It is a Dexcool Klone! which would not be a good fit for your PSD... Will it harm or damage anything? I would not want to take that chance...

I would either do a flush and pour in the Ford Premium Gold or I think Peak Global Lifetime {Green} coolant does not contain the Sodium 2-ethyl hexanoate...

Main concern is stay away from the Sodium 2-ethyl hexanoate!

If your coolant is the Dexcool Klone? I would do a flush when money allows...

Here is some good reading... Gooch is a Coolant Goo Ruu!!

DO NOT use ELC in a E99!

Second, if the coolant you added was not EC-1 Rated Diesel coolant... you need to minimally drain and refill. Best bet would be to do a proper flush, and then buy 4 gallons of CONCENTRATE, as there will always be some water left in the system. Here is a great writeup with ALL the info you will need:

Ah! I read 99, didnt see it was an E. There was that word out that it would eat the injector cup. Really I dont see how that is possbile but I have heard no ELC in an E99.

Can anyone prove this or is it an urban legand?
