This morning I go out to start my truck and I put the key in and all I hear is just click, click, click. The only thing that was on was my cell phone and that is hardwired in. I thought it could be just the cold weather causing it. I was wondering if a block heater would help prevent this from happening again. It's a '95 F-250 460. I know block heaters are primarily for diesels, but is it possible for mine to need one? I live in NC and this year its been colder than normal, so that's why I suspect the weather. Thanks.
A block heater won't help the battery, but a battery heater might. More likely, it's a bad connection. If you can twist the battery terminal clamps by hand, they're too loose. If they can't be tightened, replace the cables. Use a 4-way terminal tool to clean & resurface the terminals for the best connection.
I'm pretty sure the block heater wouldn't have done anything for your situation. They main reason for a block heater is to keep the oil warm so it moves through the engine much faster on startup than if the oil was extremely cold. The main benefit for the driver (other than not hearing lifters clatter around for several seconds) is the heater warming up much faster.
If your truck has shown a tendency to crank slowly when it's very cold outside, then one might help. You didn't mention how old the battery is, or if it's even the original one in the truck. Cold weather will definately sap the energy from a battery, especially if it's on it's last legs anyway. It might just be time for a new battery. Just to make sure though, I would get the alternator tested. Most places do it for free anyway.
Greetings from the land of 10000 degrees below zero. Yup if your battery is over 3 years old the cold can kill em at any time. BTW colder weather has been known to let the bead on a tire leak a bit or even let loose. Wouldn't hurt to check the air in the tires
Problem Solved!! Went to Advance Auto Parts, got it tested and it registered weak. So I went ahead and bought a new battery with more CCA's so I won't be let down by that other one again. Thanks for all the advice.
The battery should be changed every 3-4 years. Lots of times people think its fine all summer long and the first time it's cold that battery just dies. Good prevenative measure is to change it before it leaves you stranded.
