Where is a good place to get coolant for a 1990 7.3L? I am wanting to replace the coolant in my truck ASAP to prevent Cavitation. I have read mulitple threads and post on this forum about Cavitation but non of them really say what kind of coolant to use or mainly where to get it at. I called several auto parts stores asking for heavy duty anitfreeze and none of them had any.

Also do they make a anitfreeze with SCA's already in it?

All the help will be great, just trying to keep the old 7.3L running.

Thanks

 

NAPA sells fleetcharge that's precharged with sca's. I think there are a couple types, someone else may know for sure.

 

Fleet charge is what I get from orielly auto parts. This is a very popular topic. Wont be long till others say what to use, why to use it, and where to get it.

 

Fleetcharge with pre-charged sca's *not ELC.*

Fleet Charge Specifications Sheet

 

I got NAPA brand low silicate coolant and sca's from Ford.... just gotta change it now.

 

Mix it with distilled water 50/50.

 

Yep that's the stuff, I wish they carried the pure and not 50/50. Gets pricey at that point at about 9$/gal

 

***I wish orilleys caried pure

 

Where can you buy Fleet Charge in concentrate?

 

What do you mean concentrate? I got my fleetcharge at Napa auto.

 

The stuff that you have to add water to it, not the premixed 50/50 stuff

 

Thats the stuff we are all talking about. The link I posted in post #4 is the correct stuff.

 

tractor supply or napa carry the straight (non mixed) fleet charge.


this is the example to follow right here, when looking for just coolant,for your diesel:

you mistakenly looked for "heavy duty" rather than "low silicate".


since your at it,
now is a good time for new (from NAPA) lower and upper hoses w/new clamps and a new 13lb rated rad cap.

 

Why do I need new lower and upper hoses?

 

you might not.
however eventually they fail.
it's either do it now while the system is drained,or wait until your beside the road after a possible overheat condition,that possibly blew a head gasket or two,until you noticed a large puff of white steaming smoke,and look back into the rear view mirror and see a stream of expensive coolant all over the road that you just bought because one finally had enough and blew open on ya.
for under $20 bucks total,it's a good idea to just grab 'em now instead.know what i mean? especially if you think they're original 15+ yr old hoses.
its advised to change the cap every other flush because they slowly loose their pressure rating.
