Welcome! To assist you further, we need more info on your truck and your symptoms.

Here’s some broad info that will apply to all 1st gens: The water pump is cheap insurance. When you replace the timing belt, the water pump is right there. Change it out too. Takes an extra 2 seconds. More info HERE. <THIS THREAD HAS ABOUT ALL THE INFO YOU’LL NEED ON YOUR TRUCK!

• TIMING BELT. This is huge. The 2UZ-FE specifically is a low-interference engine. If it snaps, above idle/low RPM, the engine may become a boat anchor. Toyota recommends changing @ 9yrs or 90k miles. Sure, you may eek out 100k, 120k, 10-15 years w/o change. Hell, we've seen some make it 200k on what could be the original. However, we've also seen members w/barely 100k snap the original belt. Do yourself a favor, take a 10mm ratchet to loosen & look behind a timing cover, inspect the belt. If you find cracks, don't drive, it may be your last ride on that engine. Don't trust belt change stickers under the hood on new-to-you trucks, take 5mins to verify the belt. Those stickers cost $1-2 online, anyone can slap one on as a selling point. Belt change videos for DIY'ers are here. Shops charge $1k-2k parts & labor to to replace w/new-OEM brand (Toyota/AISIN). Aim for mechanics specializing in Toyota, dealerships charge anywhere 20%-40% more than a private shop. Don't use non-OEM parts here, and change the water pump, pulleys, tensioner while in there.
