Customer Question
2002 Explorer is knocking...

2002 Explorer is knocking. My son ran it hot when the radiator blew a hole. Ran it until it stopped itself. Now it knocks.

Mechanic's Assistant: How old are the hoses? And just to clarify, can you actually see the leak?

Water is pouring out of the bottom of the radiator. Can't see the actual leak. It ran after we put water in it. Stays cool but pours out water through bottom of radiator.

Mechanic's Assistant: Are you fixing your Explorer yourself? What have you tried so far?

I'm just trying to diagnose the knocking problem right now. I will probably replace the radiator.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I'm hoping to fix it myself. The knocking speeds up as the rpms increase.

I'm planning on going to Harbor Freight tomorrow and getting a stethoscope. It's kind of a loud clacking sound. Oil is fine.

Sorry to give you this bad news. If the engine ran that hot to the point that it stoped itself, the engine partially seized. The knock that you are hearing is a damaged piston. They can crack or distort due to excesive heat. The repair is to overhaul the engine or install a rebuilt or used engine.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey
