Hi, I have a 2006 Sienna.
I took a long drive a couple days ago and noticed steam coming from the engine towards the end. I kept an eye on the temp and right when I got in to town it shot up to the top. I stop-and-go'd to a safe parking lot and got a tow home. It seems I didn't notice the radiator cap was loose. I took it off a few weeks ago when trying to diagnose a low coolant level. I think the coolant was low at that point when a bubble came up from when I had the radiator replaced last spring, but I'm not 100% sure as I'm not great with working on cars.
My question is this: I got more coolant and put it into the reservoir, only to realize that it was already to the line in the resevoir so I now have too much coolant in the reservoir. However, the coolant was spilling out of the radiator cap and the engine was overheating, so I know there is coolant missing from somewhere. Can I just turn the van on and let the coolant go down into the engine from the reservoir? Will it get to the radiator also? Or do I need to fill up the radiator at the radiator cap? If so, how do I know when its full since the radiator cap is not actually on the radiator and won't let me see into it?
Thank you for any info you can help me with.
