What would happen if you topped of your coolant reservoir with orange dexcool preston coolant instead of the green coolant that's already in there but low... ?

they're both coolants right?

is there any difference anyways?

 

nothing i myself only use prestone but yes they are all the same just orange

 

ok thanks rangcrx, just checking.

 

I found this bit of info while I was searching around:

"Most leading technologies will work very well when used as intended, typically at 50% in good quality water. If the coolants become mixed with Dexcool®, however, one study showed a possible aluminum corrosion problem in certain situations. The other question is a concern for dilution of the protection packages. At what mix is the there too little of either inhibitor to protect the engine? As a precaution, both GM and Caterpillar instruct that contaminated systems must be maintained as if they contained only conventional coolant.
I would not recommend using Dexcool® in a vehicle that did not come from the factory with Dexcool® in the cooling system. It would be very difficult, if not impossible, to flush out all the conventional anti-freeze coolant from the cooling system of an older vehicle, and any conventional anti-freeze would contaminate the Dexcool®.
Compared to old-fashioned phosphated antifreeze, Dexcool® may be more stable and improve water pump life. Evaluations of the two technologies to compare their respective service lives have found them comparable. In fact, a Ford Motor Company study concluded that organic acid coolants do not offer any significant advantages for the consumer over current North American coolants. In a modern car with a well-maintained cooling system, current North American and OEM factory fill coolant corrosion protection can be extended far beyond previous expectations.
So the bottom line is this, if your car came from the factory with Dexcool®, use Dexcool® for replacement or to top off. If your car came from the factory with standard "green" antifreeze, use that for replacement or to toping off. Case in point, Dexcool® has been known to cause head gasket and water pump failure on some Ford OHC V-8's."

^ nice find... repped

 

yes dexcool is a gm coolant. if you mixed the green coolant with anything, i would use green or honda blue. the blue is better anyways

 

also, only use distilled water. you wouldnt believe some of the calcium deposits ive seen.

 

now this is true,i remember a engine i did where a girl thought it was ok to use C.L.R. in here radiator cause it had calcium all in it,and well i had to replace 2 hoses it was pretty funny.

 

i take it the CLR didnt work as she intended...

 

Well she left it in there,its not made to just sit its used to be soaked then flushed away she had it in there for 2months when i took the head off her car it was all cluged in the block do to the high heat broke it down like what happenes to iceCream when left out all day...the radiator was Nice clean tho just all back up from the thermoStat
