Hi, I have a 1986 Toyota 4runner, 22RE with about 215,000 miles. When I start my truck, everything sounds normal. However after a minute or so a squeaky noise begins and doesn’t stop until I shut off the engine. The belts looks fine and from what I can tell the pulleys look okay too. Any suggestions?

No, I haven’t noticed any leaking water, but I will check the level when I get home later tonight. Do you think this symptom is caused by a faulty water pump?

Be extra careful doing this: Get a short piece water hose use it as a listening device-check the w/pump,ac comp.,power steering pump while engine is idling-this will give you the direction to go from.

Suggested Repair

With the engine idling, use a short piece of hose as a listening device to isolate the squeak at the water pump, A/C compressor, and power steering pump. Also check the coolant level; a dry pulley bearing or failing water pump can cause the noise even if the belts look fine.

Conversation Summary

A 1986 Toyota 4Runner with the 22RE engine runs quietly at startup, then develops a continuous squeak after about a minute. The belts and pulleys appear fine, and no coolant leak has been noticed. Replies suggest a dry pulley bearing or water pump, and an expert recommends carefully listening with a short hose at the water pump, A/C compressor, and power steering pump while idling to locate the source.
