Hello and Welcome to FixYa.com you must have the 2.7 liter engine if so the weep hole for the water pump is inside the engine and yes the water pump goes out and leaks anti freeze and water into engine causing it to sludge up. depending on how long you ran engine with water in it depends on how long engine will last. if not long you should be ok. i would remove the oil pan and clean the oil pump screen and pan. the estimate is correct. the water pump is in line with the timing chain. i would replace the chain and guides while in there as well. flush engine after all is done. use the cheap oil to run engine and add flush then drain and add synthetic oil for high mileage engine. I own one and i had the same problem. i drilled through the timing plate a hole and braised a little pipe to the weep hole to water pump so for the next time the pump leaks it will leak outside of the engine.

DEPENDS ON YOUR ENGINE SIZE IT TAKES ANY WHERE FROM 2 TO 4 HOURS TO REPLACE WATER PUMP. TO ME $1000.00 LITTLE TOO MUCH. SHOULD COST LOWER THAN $500.00 YOU NEED CHECK AROUND TO GET MORE PRICE CHECKS. WATER PUMP KEEP COOLANT CIRCULATING THROUGH ENGINE AND RADIATOR TO KEEP ENGINE COOL.WHEN WATER PUMP FAIL IT WILL CAUSE ENGINE TO OVERHEAT CRACK OR WARP CYLINDER BLOCK.DAMAGE ENGINE AND TRANSMISSION.BOTH NEED COOLANT TO CIRCULATE TO REMOVE HEAT AWAY FROM THE ENGINE.
