when i start the engine , after coupple of minutes the negative cable get too worm, what shall i do

 

Clean the connections at the end of the cables away from the battery.

 

i cleaned the hall cables and i changed the battery and the probleme is still there.

 

Did you clean BOTH ends of the cables. Yes the battery terminals and that end of the cables should be cleaned, how about the end that connects to the engine block and alternator?

 

Thank you Mr. Bud i shall do that and i let you know the result, have a nice week-end

 

maroun, it is a common problem that water wicks up the cable in the X-Types and will cause the cable to fail, leading to what you are seeing. Sometimes cleaning the ends will help things out, but in short, new cables are what you are going to need.

Since you have things apart and are finding parts, probably a good idea to do the positive battery cable too as it suffers from the same sort of problem.

After doing the cables, you should see that your car will start much easier and you may even see your mileage come back up a little bit.
