Working on an overheating issue. All stock 04 GTI. Removed hose where it goes into the top of the motor from the pump. Flushed out pump side. Ran water hose on other side and it runs fine and stays cool. On hose water comes out of tell tale stream on side of ski and out of the exhaust back near the pump. In water it overheats. Removed pump and wear ring is fine. Water passages are clear at pump. Impeller has normal wear but not heavy damaged. Any ideas?? :banghead:
