If there are severely bent valves, and this happen in most cases, you need to remove the cylinder head, buy new valves, and the gasket. 16 valves cost around $250 and gasket $40. You need a valve spring compressor too. If you do the job by yourself it may cost you under $300. I hope not all the valves are bent, so you can solve the problem for less.

Cant find water pump on pontiacsunbird2.0hofi 1993


What motor is in it? Probably the serpentine belt drives it and it looks like a small bulk off the side of the engine held there by 5 small bolts or so.. If it's a 2.4L DOHC 4 lunger, the water pump is driven by the timing chain.

Need info on how to change the alternator on 93 sunbird and maybe a diagram if possible


  1. Disconnect the negative battery cable at the battery.

CAUTION Failure to disconnect the negative cable may result in injury from the positive battery lead at the alternator, and may short the alternator and regulator during the removal process.

  1. Disconnect and label the two terminal plug and the battery leads from the rear of the alternator.

  2. Slip the belt back over the pulley. Pull outwards on the unit and adjust the belt tension (see Section 1). Tighten the mounting and adjusting bolts.
  3. Attach the electrical leads to the alternator.
  4. Connect the negative battery cable.

Power steering pump squeels


Hello!
Are you sure it is the pump itself or could it be the Belt?
Have you tried spraying some Wd40 or similar on the belt to see if it stops? if it does then tightening the grip may help but if its been slipping a long time then replacement is the only route.
Press the blue button please to appraise my FREE! effort.
Thank You!
