WP, like everybody else said. It sounds identical to my water pump on the same engine when it went. If you DIY it’ll be about $200 (Aisin pump plus new coolant), shop will charge $1000+. It’s an aggravating DIY job. Whether you DIY or have a shop do it, use a OEM replacement made by Aisin. Labor costs are too much to have to re-do it in a few years. I’ve seen prices down to $100 on sale.
Pros: OEM replacement recommended, good price DIY
Cons: aggravating DIY job, expensive shop cost
Vehicle:
Toyota Avalon
