This minivan is constantly loosing coolant, but I don't see it going anywhere. Meaning I don't see any evidence of dripping or pooling underneath. Does it just evaporate? The rate of loss is, I may see it go from Full on the reservoir to Low, within a week. And that's without even much driving.
Also, can I put just regular green coolant in it? There's a note on the coolant cap and in the manual that says it needs some special coolant, like SL-22 or something like that. I have been using a pre-diluted bottle of coolant that's labeled for Asian vehicles, but I just ran out, and I have another bottle of green coolant concentrate that I'm wondering if I can use, but it needs to be diluted.
It also smells and feels like it's running hot all the time. It was running low on oil for awhile, but I just got it changed/filled, and it still smells like it's running hot, even on full oil and coolant. I was going to put that in a separate question but it seems related to the coolant loss.
Any ideas?
