Why does the fan motor go faster and slow at an idle in my 2005 ford escape?
The fan cuts in and out to regulate the engine temperature, based on information sent out by a sensor.
It should run more often when you're not moving, because there's no airflow through the radiator and heat will begin to build up. The faster you go, the less the fan will run, because there's natural airflow through the radiator, so the fan's not needed.
- Why does my cold air intake make my car super slow? I bought a cold air intake for my 2015 ford taurus put it on and lost power alot of power. I didn't use the normal air intake tubing i stayed with the tubing that comes in the car and put a filter at the end and reconnected the one sensor. Now my friend did this to his car and it gave him more power i don't know why mine loses power
- I bought an Actron CP9125 Code Reader to try and diagnose a rough idle at cold start on a 98 Ford 4.0 engine. The rough idle had not caused? The CEL to come on. I plugged the code reader in with just the key on and pressed read and the little asterisk goes half-way across the screen one time and stops. I press the read button again and it reads 0 codes. I was thinking it would scan multiple times to check for pending codes or other issues. I tried it with the engine running and the same thing happens. Is this code reader operating properly?
- Why does the motor on my 2001 Ford Focus SE Wagon make a shuddering noise when I'm in idle? It sounds like it wants to stall but doesn't and my gas mileage is not good. The last mechanic put after market motor mounts on but it still does this. Any ideas? I love my little car with less than 65,000 miles on it and in good shape otherwise.
