    4-Tec engine does flushing follow the same flow patterns as on water?

    I'm trying to help a mate diagnose a problem on his 2007 RXT. The exhaust temperature sensor code keeps popping up. He has had the sensor replaced before but I know this alarm is typically down to poor raw water flow.

    I understand that when on water the raw water flow is from the jet pump > intercooler > exhaust manifold. But is this the same when a hose is connected to the flush connector? Reason for asking is that when the ski was connected to a hose for flushing, I pulled the flow hose off the intercooler (ie where the water enters the intercooler from the jet pump), expecting to see water coming out, but there wasn't any. However when I pulled the outlet hose off the intercooler (the one that lease to the exhaust manifold) I was getting water flowing. I thought this should be the other way round - hence the question is the flow reversed when flushing.

    Anyone have any thoughts?

    Yes. The water is reverse direction during flush.

    Sounds like a clogged ic. T the water in like the x skis and put a strainer on the ic line to avoid future problems.
