I have a 99 Ex which has done about 77k miles. I'm in the window to change the timing belt. I've heard that the timing belt replacement is a complicated job and take about half a day. I've also been told that when the belt is being changed it's advisable to change the water pump.
Could someone please tell me what is the worst case scenario if the belts die out while driving. I've been told it can cause catastrophic damage to the engine, but I'm not sure how? Can someone please explain how? Also is it a 600$ job ?
This is my first car and hence all the above questions.
Thanks, Sikanth
