How do you fix rusted oil pan in 2002 Jeep Grand Cherokee?

Answer 1

First empty all the oil from the motor. Then remove all the bolts from the oil pan. Depending on how rusted the pan may be, replacement may be in order. If you do need to replace the oil pan also plan to replace the gasket and the front and rear main seals. Depending on your model of GC check for the parts at www.partstrain.com Also, most pans are made pretty well and all you have is top or surface rust and can be removed with a wire brush, then repainted with some Hi-Temp paint. If this is the case, still plan to replace the gasket and seals. Lastly, one of the best things I ever did the last time I replaced the oil gasket and seals, was to put a magnet inside at the bottom of the pan after I cleaned it out, right near the drain plug. This will help to collect any metal flakes.

Answer 2

If you take your Jeep on off-road adventures, you will eventually strike the oil pan on a large rock or hard surface, and the result could be a cracked oil pan. Many people decide to purchase a new oil pan, but for a lot less money, you can fix the oil pan on your Jeep. The most important part of patching a crack is getting a clean surface for the epoxy to adhere to. If done properly, a repaired oil pan will give you years of reliable service.

1. Step 1

   Remove the oil drain plug from the oil pan and drain the oil into a drainage container. Allow all of the oil to drain before placing the plug back into the oil pan.

2. Step 2

   Sand the cracked surface with 600-grit sandpaper until the surface of the oil pan is shiny.

3. Step 3

   Cut a V-groove along the crack line with the side of a triangle file or small die-grinder.

4. Step 4

   Wipe the area off with acetone to clean any sanding dust, dirt and oil from the surface.

5. Step 5

   Place epoxy into the V-groove to seal the crack. Use an epoxy with a heat rating of 300 degrees Fahrenheit or higher. Allow the epoxy at least 24 hours to fully cure before running the Jeep.
