today i changed my coolant because im planning to drive to east serrias and ski there for a week.

this is my daily driver and in know that everything was good as far as leaks and stuff.

i poured in bottle of prestone coolant and topped off with distilled water.

now i have coolant dripping from my water pump weep hole.

i guess no big deal, waterpump is probably old and it's better to replace it now.



the weird thing, this happened to me for a 3rd time, every time, different car, but always with prestone.



anybody had similar experience?

Never had such a problem, but in any case, it's best to mix the coolant and distilled water before pouring it into the radiator. A mixture of 50/50 is adequate for most regions of the country and most driving conditions.

Yes.Suggestion.Mix the Prestone to 50/50 BEFORE pouring it in.
When you put the prestone In The car,without mixing it,then the Ratio of Coolant to water is all Fugged up.You don't really know what you end up with.Could be 70/30,80/20.Who Knows?
Mixing it before you Pour it in,Ensures that your Ratiio of coolant to water will be What you mixed.
and coolant out the weephole?..get a new water pump.

i just use the already mixed 50/50. sure, its half water but that way you dont have to worry about it or go somewhere else to buy the water.
