My 2010 Explorer has a high idle when starting it this winter. I kick it down and it quits but have been getting lower gas mileage and it seems to take forever for the motor and tranny to warm up.
My Explorer has been running way different this winter. A
couple of months ago I was told the mechanic added 2
gallons of anti freeze. Where did it go? I never saw a leak at
anytime. My idle has been way high when starting it when it's
cold. I have been getting lower gas mileage all winter. I have
to have it warmed up before getting on the highway as it
doesn't seem to want to shift until the temperature is at
normal. My drive/overdrive has been goofy for the past few
If you where 2 gallons low on coolant, then the engine would have ben overheating. It only takes 2 gallons max to fill the system. Otherwise you may have a bad thermostat, replacing the thermostat may help the problem.
He said 2 jugs of coolant so I assumed 2 gallons. It never overheated which is why I was surprised when he said how much he added. I have been keeping a close eye on temperature and coolant level. Looked for leaks several different times but never saw any. Will try the thermostat! Thank you!
If you think you are loosing coolant, smell the exhaust. See if it has a sweet smell to it, and you would notice more white smoke coming out the tail pipe. This would be a head gasket.
I got the thermostat changed today and they cleaned a few things and no more high idle when starting it and seems to work great now! Am hoping that is the last time for having problems for a while as I love my Explorer! Didn't take anytime at all for it to warm up after I had let it sit for a couple of hours. Thank you for your help!
Something still wasn't quite right so I took it to the Ford garage and after going through things, they are going to check for a stuck lifter. Hopefully soon it will get done and am hoping to not have anymore problems after this for at least a year. They did find a tiny hole at bottom of radiator but said to just keep an eye on it and to top it off every now and then.
So far so good, thanks for letting me know. There are oil additives to put in to try and loosen up sticky lifters. I hope they try that first as replacing the lifters would be expensive.
No stuck lifter. To check anything with the timing, they would have to remove the whole motor. Keep driving until something kicks a code.
Yea, if it aint broke, then don't fix it.
