This vehicle began to run hot about 4 miles from home yesterday. I pulled it over as soon as the temperature gauge meter touch red or almost max to the side of the freeway. I turned the A/C off. I saw a little bit of white steam emitting from the passenger side of the hood near the belts. I turned the engine off, opened the hood and looked at the radiator and engine area. I noticed some white spots scattered on the radiator upper hose area. I checked the radiator cap and it looked good except the inner rubber core had a small defect or chip on the edge. I don't know if that could cause a leak problem or not because I did not see any leak before removing it. The coolant was about a gallon low after filling it up before leaving 10 minutes ago. I waited for it to complete cool down and drove to the yard. Today, I checked it again. The coolant appears to be visible with the cap off so I did not add any more. The reservoir overflow was still full from me adding enough to go from half full to full. Today, I removed what I added yesterday. I started it up on the second try and it only was a few seconds to start. I checked the cooling fans. Both were not moving. I turned on the A/C to max and checked the fans again. The passenger side fan was now running, but the drivers side fan was not. I was thinking the one running is probably the ac fan. I checked the fan connection and could not see any disconnection.
Why did the radiator fan not come on? I begin to look for leaks or problems around the entire radiator, hoses and engine. I did not see any except the white spots scattered on or near the hose, possibly coolant stains from the radiator. With the engine running and ac at max, I placed a cardboard layer under the engine and checked for leaks. On the drivers side underneath the engine, I began to see water dripping continuously onto the cardboard. I could not see where precisely the water was coming from. I was wondering if it was coming from the water pump, A/C condenser or a leak in that small area. The radiator fan never comes on. The A/C cooling fan turned off when I turned the A/C off. I captured a quick video of the water dripping underneath the passenger side of the engine, the fans, engine and no smoke coming from the tailpipe. During my 5 minute inspection, the engine ran smooth at normal temperature during the whole time. Is it the radiator fan, the water pump, radiator cap or what and where is that dripping water coming from? It stopped dripping when I turned off the A/C.
have the same problem?
