Hello I own a 2009 rav4 sport with the 4 cylinder engine. A week ago I was driving and the water pump went. I towed it into the shop and they informed me I need a new engine. The price was 7500 for a used and 17000 for new. The engine only had 220000km on it. The engine will turn over just sounds really slow like it's not getting power. I check the fuel pump battery spark plugs all appear to be good.
