The emission pump on my 98 Toyota Tacoma squeals in the cold weather. Is the any way to lube it to get it to stop squealing?
I know the dealer would say replace it but when it’s warmer it is fine.
Are you sure it’s not the drive belt that’s squealing because it’s loose? Rubber belts expand in cold and contract in heat.
I’m confident, based on the sound, but I haven’t confirmed it. I should do that this morning.
