Hi all.
So I change coolant about, maybe two years ago, I did it by flushing the radiator, fill it with distilled water and flush it again several times, while running the engine a little bit to circulate, diluting the old coolant and flush again.
I then bought much more Toyota coolant than what's needed to flush the distilled water off the circuit and get the correct ratio. Trough the course of some days after, I repeated the flush until I was sure there was no more water in the coolant than needed. I know it seems wasteful. but I couldn't for the life of me take out the drain plug, it's such in an awkward position to remove and it's really tight, I used 6 jugs of Toyota coolant, and kept one for spare if needed.
I made sure there was no air inside by using those special funnels to purge the air out everytime.
And our tap water is terrible so I didn't want to use it to flush.
The old coolant (also Toyota brand) seemed fine, no major particles or color.
So now, after some years of light usage, I'm getting these pink crystals all over the tubes and edges of the radiator and I don't know why.
I only noticed the tube leak before so I ordered brand news ones and got new stainless steel things (i don't know the name in English) to tighten around the radiator and engine.
When I was going to drain the radiator to change them, I noticed also on the edge of the radiator, but I'm not sure if its leaking from the radiator itself or its spill from the leak in the tube. Also, I don't think it's the expansion tank because it fills normally when the engine is hot, and goes down when it cools, so no pressure from the cap.
I'm going to clean it good, change the tubes to the new ones (since these are the same age as the car) and check again if it continues.
Any ideas?
Cheers!
