It can get in through the timing cover. That does car does not have a "timing belt" cover, but it has a "timing chain cover." There is a BIG difference, as a timing belt cover does not have coolant and oil running through it, but a timing chain cover does have both coolant and oil running through it.
No, but you should, every second timing belt. All the same labor is required to change either part, and the cost of changing the timing belt or water pump is almost entirely labor cost. "While we're in there" is actually legitimate in this case.
It is behind the timing case cover behind the crankshaft pulley.You have to remove the timing belt to replace the water pump for this repair.
Inside the timing case with the timing belt and balance shaft belt.
You have to take off the serpentine belts so that you can remove the pulley for the water pump. You also have to take off the cam head so that you can get to the timing belt case and remove the plastic splash guards in front of the water pump. Remove the timing belt, then there are 4 bolts attaching the water pump. Remove those bolts and then disconnect the water intake and put your new pump in and replace the timing belt. **Make sure that your timing marks are located where they need to be before replacing the timing belt.**
Buick regal doesn't have a timing belt. It has an accesory belt and is change between 50,000 to 60,000. In my case i replace the accesory belt when my car was 80,000 milles.
If the timing belt has broken, the usual case is the motor has bent valves and is destroyed.
Ignition timing is not adjustable. Cam timing is adjustable by the "guess" method unless you are replacing the timing belt and using the timing marks on the belt drive cogs, in which case you need a repair manual that has detailed instructions.
In short the water pump is behind the timing case cover,you have to remove the fan shroud,fan, timing belt,drain cooling system, and alot more information that is too lengthy to list.
Generally if the timing belt breaks, it will not do damage apart from the cam, etc. being out of time. However, if the belt streches thru wear and slips on timing, this can do serious damage, such as beding rods and valves. Sometimes in this case if you are really lucky you can have a rod go through a piston, then you need a major rebuild.
Front of engine (behind serpentine belt).
Timing belt manufacturers recommend replacing timing belts every 60,000 miles. In the case of a volkswagon I would never exceed that milage. The water pumps on volkswagon engines have plastic impellars, and they are very prone to failure. I have seen them fail at 50,000 miles on several occasions. The water pump is driven by the timing belt so both should be changed at the same time. EVERY TIME.
every pulley has a mark on it that matches a notch on the inner timing belt/ oil pump cover, line up the white lines on the belt with these marks and that's it.. all 3 marks will line up belt-pulley-case.
