准备买个二手车,作了一下功课,在wikipedia上发现丰田的2.4L发动机有如下问题:
Reports are surfacing on the internet of problems with head-bolts (not typically a part that wears-out) becoming stripped out of the aluminum block in the 2AZ-FE engine, including but perhaps not limited to the Toyota RAV4 and Toyota Camry. Compounding the problem, according to these internet claims Toyota is not acknowledging and repairing what owners think is an obvious design problem beyond the engine warranty. The problem begins when coolant level begins to drop and on investigation a coolant leak is discovered on the intake side of the block where a piece of foam is installed, evidently to shield the plastic intake manifold from heat. When the problem is investigated, it is typically reported that three head-bolts located at this area of the engine may be pulled-out with very little effort, practically by hand.
更发现该型发动机竟然用途这么广泛:
好像涵盖了丰田所有的畅销车型. 请问该问题出现的概率有多高?最近几年的车也有这问题吗? |
