Comply with me as gurus train me how to diagnose, fix and modify cars on AutoBlog’s Wrenched.

[00:00:30] As you can explain to, I’ve had this vehicle for a actually prolonged time and the battery ultimately pooped out on me.

[00:02:30] on your ratchet to access this bolt. When lifting the battery, make absolutely sure to hold it straight up and down and seize from the bottom, or use it really is handle.

[00:03:30] Just before installing the new battery, cleanse the terminals and implement battery lubrication, recognized as dielectric grease, to assist lessen corrosion in the upcoming. Now, location the new battery in the holder and safe it with the tie down bolt. It really is exceptionally vital to connect the good or pink terminal to start with when re-putting in the battery for the exact same reason we reviewed when getting rid of the battery. Likewise, the rule of not touching equally terminals alongside one another nonetheless applies, so observe your software placement. Last but not least, connect the black terminal

[00:04:00] and tighten down with your ratchet til the clamp or the bolt can no for a longer time be twisted. There is no have to have to in excess of tighten.
