Cooling issue please help :(
So after about a month or so of trying to replace my timing chain, I FINNALY get the car to turn over yesterday. I took it for a VERY SHORT drive around the block and when I put it back into the garage the engine is hot and there's smoke coming from my radiator cap and heat shield. Anyone know what's going on?

Topping the radiator off is different from bleeding the system.

still having issues? Couple questions for you, when you drove your car after it gets to normal operating temperature (assuming it does) does it get hotter than normal or overheat? Does your lower radiator hose feel hot to the touch? If not, then your thermostat may be failing to open.

After I took to around the block it stayed the same temperature, when I took it into the garage steam was billowing from my radiator cap. I felt the lower hose and it was still cool... Pretty confused

Your thermostat is not opening if the lower radiator hose is not warm/hot then. Around the block that isn't very much driving to allow the car to warm up. Also, are you certain you temp gauge is working correctly? It could be reading wrong, could also be the temp sensor. What I suggest is take the thermostat out, leave it out and fill the radiator up with coolant cuz you will lose some when removing the thermostat. Then follow the steps for bleeding the system of any air, what i do is raise the front up high on jack stands, open the radiator cap and put a funnel in the radiator opening and put coolant about half way up the funnel and run the heat on high. Rev the motor to a steady 2k for a few seconds at a time and let off. Check the funnel to see if the coolant you put in there is gone and add more if so. Next test the thermostat. Take the thermostat and boil water to 200 degrees and drop the thermostat in there. See if it opens, then take the thermostat and put it immediately in cold water. Do this a few times to see if the thermostat is failing to open. After that, drive the car and after a good 10-15 min drive see if the lower hose is hot or not. I think you have either a thermostat issue, or air in the system, possibly both.

Okay guys, I just got a new oem thermostat and installed it. Bled the system and I started it up in 15 degree weather and it still got to temp (5/8 up on the gauge) in under 5 minutes. I also hear random ticks coming from my manifold while the car is operating and a steady dripping sound in my manifold when I turn it off...

was the lower radiator hose warm/hot when it got to the 5/8 on the gauge? What manifold exhaust or intake side? I take it you have no smoke anymore? |

Lower radiator hose was warm and he ticks come from the exhaust side, and no I didn't see any steam come from my radiator this time. I haven't gotten to check the temp sensor yet either

How long did you run the car? Did you accelerate it for a while at all? the radiator hose not getting hot means the thermostat is not opening, which if you changed that then you might still have air in the system.
