Just changed coolant not staying full
 

I just flushed my coolant and had not problems in the past with it dropping below the minimum and now it will not stay above the minimum. I put 4 gallons of caterpillar coolant in it and it was fine at first then it started dropping. Does it need more than four gallons after I flushed it. I'm pretty sure its not my head gaskets just had them done last Feb. along with arp head studs, egr, and oil cooler.

leaking petcock?

How fast is it dropping??

It is supposed to be below the "min" line in the plastic. min is the new max. Aprox. 3/4 inch below "min" line is the new min line. Some of the degass bottles have a updated sticker on them. pt

about a week is how long it takes to drop

Check the petcock, or it may even be a leaking water pump or a hose. :humm:

I am not to sure on where the petcock is located can someone lead me in the right directioon.

Not sure exactly where the petcock is at. But they are usually on the bottom of the radiator on the opposite side of the lower coolant hose.

Is your truck lifted or leveled?

Who did the headgaskets and how were they done? They could easily be bad again. I highly doubt the petcock started leaking out of no where.

No it is not leveled or lifted and ford did all my work and the head gaskets where never bad they did a compression test and there was no leaks but i said just to be safe put new head gaskets on since they put head studs in. I crawled under there and looked for any leaks any I could not find anything only thing thats leaking is my oil and I think I know why thats leaking.

Try taking the top off the degas bottle and let it run, get it to operating temp and add coolant to keep it where it needs to be, this should help purge the air out, this will take a while , maybe up to half hour so be patient. once you are done put the cap on and let it be, moniter it for a couple of days but don't automatically put coolant in it unless the bottle is empty, that way it will find its own level..

Well if Ford did the job, you can bet they didn't deck the heads, so blown headgaskets are still my guess. Ford did my ARP's once for me too, it was the shortest time headgaskets have ever lasted on my truck. This really isn't that uncommon.

New headgaskets don't mean squat if the head/block isn't flat.

Who's tunes are you running on that SCT? Which tune?

I am not running anyones tunes just the ones that came with the tuner and the coolant hasnt moved in a couple of days now its staying right at 3/4 below the min. And whos tunes do you guys suggest I would like a nice tow tune bc the one that came with it sucks imo and the hot tune is nice not too much smoke but enough to have fun with and not too much power bc i dont want to tear up anything like the tranny And i never use my economy tune

Running an SCT without custom tunes is just like running any other programmer really...

There are a lot of good tuners out there, Innovative Diesel, GoGo, Gearhead, QuickTrick Auto. I love my Innovative aggressive Tow.

Don't get an economy custom, they're a waste of money. A higher HP program will yield the best mileage.

Innovatives hottest tune will probably be safer on your trans than the tunes you're currently running. The trannies in these are only as good as the tuning you're running.

ok how much does innovative charge for a tune and do you have to buy 3 or can you buy one at a time bc i would like to get the aggressive tow and the hottest tune they have and what is there number?

$65 for standard tunes ea. $80 for extreme tunes ea, or $165 for 3 tunes.

Let me google that for you :c:

If your coolant level has stopped dropping as well you might be ok. Some of them will "self level" sometimes. I have seen some 6.0's push a ton of coolant out until it gets almost in the bottom of the bottle and then they're happy. Just keep an eye on it and keep close attention on the smell of your exhaust.
