Quick coolant question

[Misael]

When i got my truck it had "green" coolant in it, it was a little bit on the low side on the degas bottle so i added some distilled water. Last week I loss some coolant putting in the blue spring on the fpr(moved hose out of tstat, it was stuck open) so I filled it with distilled water and about half a gallon of the zerex G05 stuff.

I want to replace the t-stat tomorrow and drain all the mixed crap out of there, will it be okay if i just drain both engine plugs and radiator and fill it with the zerex concentrate? Or do i need to fill with distilled and flush the crap out? My deltas were acceptable(max 13 average 10) when I did a 35 mile highway trip to verify using CTS. I plan on replacing the oil cooler and doing egr delete in the next few months regardless.

Thanks for the help!

Do it right. Flush the crap at out of it. You don't need to start out with distiled water but you need to finish with 24 gallons of distilled water.

Sounds good. Called a local NAPA store and they have a bunch of the ZXED1 concentrate now I just need to track down the Restore stuff. Thanks for the help!

shouldnt the flush be done right when you plan on replacing the oil cooler?

Not necessarily, but it definitely helps. I'll be doing a flush here shortly (I've got the Ford Gold Coolant in my truck now ) but the oil cooler was already replaced about a year ago... I'm just going to do the flush. Granted... the new oil cooler may already be clogged, but I'll find out soon enough depending on my temps - I'm assuming.

Just trying to find a good price on some Red ELC Coolant now...

Looks like I'll just do a regular flush without the chemicals until I have a replacement oil cooler+egr delete while its taken apart. The EOT/ECT are still within 15* so I don't want to run the chance of doing a full flush and clogging up the oil cooler then not having one to replace it with. My truck is my DD so i need it running properly! Looks like a good distilled water flush to get the mixed coolant crap in there(some unknown green+g05) will do the job and throw in some fresh zerex ELC+distilled water in the mean time.
