    Temp heat switch wire is connected to my temp sender?

    OK, your motor could be either one piece manifold, or manifold with end caps, and none have a temp switch only temp sender. I would disconnect the Ten/Blue and tap it. You could install a NPT Tee and install both

    07 5.7 mpi separating coolant fitting

    Ya know if the drain side of the fitting is clogged, then there will be water pressure above the check ball but not as much below. If it wasn't clogged then pressure above and below would be about the same Remove the lower end hose from the fitting (drain side) and blow air thru it. Maybe...

    another crank / no start thread

    OBD scanner won't work, need a TechMate Pro or Diacom software from rinda.com Oil pressure switch has nothing to do with the fuel pumps turning on/off on a MPI motor, only works with carb motors. Do check the fuses for the main power relay and fuel pump. I noticed when you first started...

    Volvo V6-280-M Beeping

    Going to need the motor scanned to find out. It may be overheating even though the gauges reads lower. The gauge and PCM do not use the same sensor. Can use a IR Temp gun to verify the thermostat housing reads same as gauge. If it does the PCM sensor may be off or other things. Just no way...

    Temp heat switch wire is connected to my temp sender?

    Someone moved it would be a guess. Don't know your serial number but both the switch and sender should be real close to one another on the thermostat housing

    07 5.7 mpi separating coolant fitting

    First law of hydraulics is, pressure exerted on a confined liquid is transmitted with equal force on all areas. So pressure on one side is exactly the same as the other. To prove, move that one to the other side and see if it still pops same side

    07 5.7 mpi separating coolant fitting

    It should not pop off. The pump might produce 30 psi at the most at high rpm, and that shouldn't cause the issue You have a 3 point drain system, so things are both fill and drain Pic is for 4.3 but works the same. Color scheme Green drain, Red raw water, Blue bypass when thermostat is closed

    07 5.7 mpi separating coolant fitting

    ok It is a check ball and has 2 functions Keep water from passing up into the manifold when boat is running Drain water out during winterization The check valve I posted is there to help keep the mans full once the motor stops. Yours should not just pop open when running. It should take a...

    I need a website showing boat part number

    Those links is what I use to find part numbers. It sounds like your looking for a exploded view kind of manual. Don't know if there is one. The service manual should show a lot of locational info, but it to may not show everything.

    07 5.7 mpi separating coolant fitting

    You have replaced it twice? Didn't know it came apart, does it unscrew or just pop apart? If its the pic then it doesn't pump water, it just keeps water from flowing back

    Swap from 3 Blade prop 19P to 4 blade prop

    Won't hurt a thing short term. Your probably not going to reach WOT RPM as you did before, so a bit of lugging but probably not enough to worry with now

    Swap from 3 Blade prop 19P to 4 blade prop

    If you went to a 4B-17 that might do it, or going to a 3B-17 will jump out good. I use to use a 3B-19 when pulling skiiers and tubes and go back to 3B-21 when just cruising. Could over Rev with the 19, but it would sure get the boat up fast

    Swap from 3 Blade prop 19P to 4 blade prop

    Not necessarily. Everything has trade offs. 4B-19 is like a 3B-21, so using a 4B your going to loose RPM at WOT. The 4B bites better and therefore has less slip, but depending on the boat (heavier) a 3B will get you up quicker because RPM's will come up faster and put the motor higher in its...
