Q: Car won't start after driving without the cap on the antifreeze.

asked by on

I was putting antifreeze in my explorer and forgot to cap it back. I want driving and I noticed the car was smoking. I pulled over and put the cap back on. I drove almost home and the engine turned off at the stop light. I tried to start it and I'm getting a lil sound like it wants to crank but it doesn't. If it got all over my alternator would that stop it from turning over??? Please help me

My car has 181000 miles.
My car has an automatic transmission.

Hi there. From the description you have provided, antifreeze getting on the alternator would not keep the engine from turning over unless the battery was low. The alternator could have been compromised by the antifreeze, if your vehicle was driven far enough with the alternator not charging.

This would account for the engine turning off and not turning over, assuming the engine was not overheated due to the low antifreeze level. The battery and alternator require inspection. I recommend having a certified mechanic, such as one from YourMechanic, determine why your vehicle won’t turn over and suggest any needed repairs.

Q: I just replaced the battery in my car and as I was driving I stacted to lose power and the car died it cranks but won't start

The new battery that you bought should be fully re-charged. Confirm that the engine immobilizer system (security system) is not activated thus preventing the car from starting. Check for the characteristic, but momentary, whirring sound from the in-tank fuel pump...

Q: What kind of oil should I use, being that I have a lot of miles on it

You should only use 5w20w motor oil and Toyota long life antifreeze in this car. Just because the engine has high miles you should not change any of the recommended fluids for the vehicle.
