Hey gang,
I pulled off my throttle body to replace the screws on my TPS (they were stripped and I need to adjust it), and in doing so removed the coolant hose that feeds it (pic below).
Question: (dumb question but I couldn't find anything covering this in the forums)
As this is the highest point in the engine the coolant goes through, is the very small amount of air in the hose a problem, and do I need to now bleed the coolant lines to get rid of those few potential bubbles, or am I ok to just re-install it as-is?
I remove that hose to aid filling the coolant every time I replace the coolant. There is always a bit of air left in it. That small amount of air will not hurt anything and will eventually make its way out of the system as you run the car. So unless the coolant level went down a lot during your work (not likely), it should cause no issues. So just reinstall it and it should be fine.
you can pour more coolant if you want that hose off and just stop when it starts to come out. you can if you want but you dont have to.... only if it will make you feel better
@cr-rex the below one? Yes - I needed more coffee. My original question clarified that the hose from TB out to WP is ok to have a little air, as it's v short. I'm wondering if the other hose - the one from motor to TB in - can also have a little air. It's a bit longer, but didn't leak much when I disconnected it. I imagine it's ok, right? I imagine I'd slightly top it off like @DaleClark mentioned.
Yes. The little bit of air that was trapped should be inconsequential, but once the engine is run up to operating temp (and cooled down ), you could remove the fill cap above the water pump and add what little it will take…distilled water or coolant.
You might double check that your overflow is at the full mark beforehand.
