High Pitch Squeal at start up -'04 Kia Optima 4cyl.	Sign In

My '04 Kia Optima makes a high pitch squeal (perhaps from the power steering pump) at start up. The sound goes away after about 5-20 seconds and doesn't come back in normal driving. Any thoughts?

Possibly just needs a new belt. Check that tension is proper. In that it goes away the belt itself is a likely problem,

Hello Tom,
Thanks for the reply.
The belt is new and the high pressure hose was just replaced as well.
The belt seems to be adjusted okay... Is it time to replace the pump? 60K

Life expenctancy of the assessorie pulleys and pumps is chiefly unknown. By main pressure hose do you mean the upper radiator hose? Did it blow out or leak on you? If so the anti-freeze may have caused a stickyness or something on the belt new or not some will make noise.

Try sparying some WD-40 on the belt grooves before you start up and would expect the squeal. If it stays quiet I'm blaming the belt. They aren't all created equal and some are just noisy. Various aftermarket belts are sold as "quiet" belts - ask for that or an original.

If no change try taking if off and spin the pulleys and feel for something wrong. Might be tricky because you said it went away.

You should make certain fluids are properly filled and if you really suspect the PS pump I'd suggest changing its fluid first,
