volvo penta web site or forum??? HELP!
21 years ago I purchased one of the first 2003 engines produced. Of course I had many overheating problems but all of them were relatively easy to solve. First of all I removed permanently the heat exchanger(it was an engineering disaster. Here are some of the other problems: Barnacles in the intake valve, many pump failures, the outlet hole in the back of engine block to the manifold clogged, the elbow at the pump inlet clogged. The easiest way to solve the overheating problem is to dismantle the whole system, including the head, and clean all the passage ways. I do this every third year. Note that Volvo Penta parts are very expensive so with the exception of the head and rocker arm gaskets I make my own. Also note that the whole injector system is from Bosch and a lot cheaper from Bosch than from Volvo. Also the starter is from Hitachy and the alternator from Paris-Rhone. Any more questions please E mail me Good luck
