I replaced the water pump on my 1997 acura cl 3.0 v6 vtec. I set the timing how alldata said to. (Lined up marks on timing drive pulley and both cam pulleys) and put it all back together. Now when I start it the motor runs rough for about 45 seconds then it smooths out but won't rev past 3000 rpm. What are some possibilites it could be?
looks like the force belt broke, or is slipping. The force belt connects the engine to numerous aspects, like your alternator which rates your battery, the water pump, which pushes the coolant around the engine and radiator to relax the engine, and your skill guidance pump, which pressurizes the hydraulic fluid to your skill guidance. do no longer force the motor vehicle back till you fix it. you're able to desire to heavily blow out the motor by using over heating it.
reset the ecu, by disconnecting the battery cables off the battery for 30 mins and then reconnect them and see what happens
Ive seen this before. u replaced the water pump, which means u drained the coolant, replaced the pump, and filled it back up again. When u filled it back up u created big air pockets in the coolant system. Small air pockets are always in the system, but wont cause a problem. Big air pockets cause the engine to idle rough, like its misfiring. Then when u go to press on the gas it stalls, or it wont rev past a certain point. Ive had this problem myself a few times, replacing water pumps and lower radiator hoses. About the best thing u can do is just let the car run and idle for an hour, maybe even 2! Then rev it when its still parked at a higher RPM, just to flush out those pesky air pockets. I know it wastes gas, but thats what i think the problem is. Air pockets are something that most ppl dont think about when they drain and refil the cooalnt components.
