fabulous ELC gasoline / diesel concentrate

wonderful world class, Shell group (Pennzoil Quaker State Wolf's Head Shell) high quality red color extended drain concentrate. Nitrate-free formula means it can go 600k miles cars 1.2 million trailers. (No need for SCA (supplemental coolant additives). Able to get -90° freezing/ 277° boiling protection with an ideal 70% concentration. so hood. it will work with tap water if distilled water not available. i recommend gasing out the chlorine from your tap water two days prior to coolant change (cap off of some tap water-filled jugs needed for your final mix) bonus tech tip: if your coolant cap does not hiss when slightly opening with a thick rag %26 caution, then it is defective as it does not hold proper pressure and lowers your protection. change your cap every 100k miles or 10 years

Coolant for 1999 F-250

Best coolant I could find for my 1999 F-250. Doing a complete flush out and replacement as required. Best price by ordering online. All four jugs came each sealed in a plastic bag with no leaking.

So far so good :-)

I did a bunch of reading on what was right for my 6.0L Power Stroke (this is a finicky engine when it comes to coolants) , this seems to be what one needs. I will write more when I rack up the 600,000 mi it's supposed to last ;-) I like the price and looks like it is good quality
