I was browsing this forum today reading about Antifreeze and was reading somewhere that using "Pure Antifreeze" is more harmful then using the mixture of water and antifreeze.

for some dumb reason about 4K miles ago I thought using Pure Antifreeze would be better. I've been using it for about 4K now. Engine never over heats as far as I know, but I plan on changing the antifreeze in the next couple days with the right mixture.

could using pure antifreeze hurt anything for the past 4K miles??

also......Now that I have to change it out, last time I did the flush, I snapped off that plastic screw that the antifreeze drains out of since its just made out of cheep plastic leaving only the threads behind holding the fluid in. How do I drain the Antifreeze now that the drain plug is snapped off?

any help is needed and appreciated! Thank U!

 

it never ceases to amaze me. mat you are one funny guy.

if it hasn't overheated yet then you'll be ok to flush it with water and refill with a 30-70 mix. 30% coolant 70% water.

drain it at the block first and then pull off the bottom radiator hose.

 

I tried to get the plastic screw out of mine when I changed my antifreeze a few days ago (for grins) but something holds it in the valve. I wonder what the procedure is to replace it when it breaks like that.

You can save the antifreeze thats in the truck and reuse it. Just use a clean drain pan to catch the fluid. My drain pan has a pour spout so I can pour it into gallon jugs (like empty gallon size clean distilled water bottles or your original antifreeze containers if you still have them) using another funnel on the gallon jug . Then mix a ratio of one gallon of your antifreeze with one gallon of distilled water. Then use a filtered funnel when you put the antifreeze back in the degas bottle on the vehicle.

 

Flush it right away, and fill it with the premix stuff, that way you hopefully can't goof this up again.

 

you know that guy didnt pass his drug test with that nasty lookin urin sample

 

Talking about tests, the Amsoil coolant I just put in cannot be tested with an old style antifreeze tester. The dealer gave me special test strips that are supposed to give freeze/boilover temperatures and PH level. They did not work for me so I don't know if the strips were bad or if the antifreeze was not mixed good in the degas bottle since I added distilled water last and did not premix the distilled water and antifreeze. Im going to drive the truck for a week and get some new test strips in about a week. Then Im going to try the test strips again and see what happens.

 

I've never heard that you can't put pure antifreeze in. Personally I have always mixed mine but I never would have thought that it would be damaging to run pure. But I guess you learn something new every day. What kind of damage can running pure cause???

 

Try using an allen wrench, on mine the inside of the screw is hex shaped so you can use a socket or an allen wrench...although Im not sure if it rounds out as you get past the "head".

 

Pure antifreeze does not conduct heat well and the engine could overheat along with the problems that occur when an engine overheats. Water is what carries the heat. I have also read where pure antifreeze can actually raise the freezing point of the coolant when it gets past the 60% level.

I wouldn't worry about it. Just leave it like it is. But if you're really worried about it, just drain about a gallon or two out and fill the resevoir back up with water. Then you will have at least a little water in it.

Btw ALWAYS use at least a 50/50 blend of antifreez in water unless the bottle tells you different. Antifreez helps protect your engine so if you use less than a 50/50 blend you may run into corrosion issues, and the water will boil at a lower temp. This can be really really dangerous!!!!!

 

Boy, when it rains, it pours. lol. That is terrible advice.

You really don't need, or will recieve any added benefit, from using more than 25-30% coolant, unless you live near the Arctic Circle. If no damage has occured so far, you're lucky, but keep in mind that the more coolant you use, the hotter the engine will run. With too much coolant, the boilover temp will exceed the temp where damage occurs, so you basically will ruin your engine without realizing it until it's too late.

 

It seems like EVERY thread I have to explain why manufacturers recommend a 50/50 blend of antifreeze. https://www.f150online.com/forums/sh...=234214&page=2

As for it causing your truck to overheat, I'll admit when I'm wrong. If anyone's truck has ever run hot because they put too much antifreez in the radiator, then please post here and I will not say anything else.

 

here's a couple good reads for you...

This first one was found by another member here who was arguing your point, at first...

Coolant Mix and Overheating

And this one is a White Paper from Redline Oil.

 

Ok buddy. The first one is talking about aircraft engine. And I know one thing. I'm not gettin into an aircraft with an overheating problem. End of story. And I wouldn't take this guys's word over ford's
And the Redline article is talking about racing applications. My truck is not a racecar. Go to the Ford Dealership and ask them what to use. I bet a 35% blend will void the warranty.

 

Jebus Christ, you're dense. I don't need to go to the Ford dealership, I've owned and operated my own auto repair business for nearly 15 years. Look, like I said, you can do whatever you want to, even if it's foolish, but you're giving some really bad advice here (especially in this thread).
