Coolant level confusion
I consider myself fairly knowledgeable about cars but checking the coolant always seems to confuse me. I have a 91 4runner v6 4x4 manual. Right now the engine is warm and the level in the over flow tank is nearly empty. Is this normal, or should I fill it up? From what I understand the coolant normally in the overflow tank gets sucked into the radiator to help cool the engine when it warms up, right? The coolant level should be good as I checked it a few weeks ago, and after inspecting all hoses, caps, water pump I don't see any leaks. Thanks for any help guys.

So if your expansion tank was full (or 1/2 full when cold) a couple weeks ago and now its empty then you have a leak. Or it is possible there was air in the system that got burped out which created a vacuum and sucked dry your tank.

I would make sure you are checking the level consistantly and make sure you have a good rad cap. If you check the level each morning when the engine is cold you will know after some time if there is a leak or not. As stated above, the min/max level in the expansion tank is for a cold engine, so checking the expansion tank when the engine is hot is meaningless.

Thanks for the help guys, I'm definatly going to look into this. When I refilled the radiator after getting it repaired I had the cap off and the heater on with the engine on to burp the system, and I've already had the headgasket recall done. I don't see any leaks so I hope it isnt another internal leak lol. Please, pray for me, lol jk

I am having a similar problem. Ever since I did my timing chain about two moths ago, I have had to refill my coolant reservoir probably three times. So assuming i do have a leak, what are the likely culprits?
Could it just be a bad radiator cap? I replaced all my hoses and none of them show any signs of leaking. And the I see no evidence of leaks around the timing chain cover, though I suppose these might be hard to see.
