Strange Overheating Issue
I am hoping you will be able to help me figure out what the issue is!
To start from the beginning.. I was driving down a road at 40mph with stoplights every 5 blocks or so. I noticed my A/C stopped blowing cold air, and i turned it up so it would blow harder. After a minute or so of warm A/C, I started noticing some steam coming out of the front driver side of the hood. I pull over, and let the car cool down. NO leaks or drips coming from the bottom.
I let her cool down and limp it home about a quarter mile and filled up the coolant that had steamed off and began to diagnose the situation.
I noticed my radiator fan was not spinning. I took the car to a shop to have them look it over and see what they thought. I told them to take a look at the fan because it as not spinning and the cooling system in general. I figured the fan was not kicking in, so the coolant was not being cooled, which caused the system to overheat and purge some steam off to relieve pressure. The steam comes from under the support that holds the radiator, I can't see exactly where it is coming from. It looks like it's coming from right below where the big metal support piece covers up the top of the radiator. It's a low volume of steam, about equivalent to what you see when you boil a pot of water. Definitely noticeable, but not billowing smoke.
The shop said the radiator fan had seized up and they agreed that there was no leaking. I replaced the radiator fan with a new OEM one, but it still does not kick in and start spinning. Could i have a blown fuse or something? Hopefully it's something simple like that!
I also noticed the bottom left pulley (bottom one on the passenger side) only spins a little bit every few seconds. Every few seconds it will do maybe a quarter or half turn. Is this normal? I believe it is the water pump pulley, but not sure. It's the one with the three bolts on the face of it.
- a/c stops blowing cold (but still blows just fine)
- steam comes up form driver side near top of radiator
- no leaks or drips on to ground
- replaced radiator fan
- replacing fan didn't help situation
Thanks in advance for any input!
