Volvo 2002 season startup

I had a long talk with a very experienced diesel technician yesterday. The following are the start-up instructions he gave me. This is for the first start-up of the season.
He said that the volvo penta 2002 was often hard starting.

0. Make sure batteries are topped off.
1. Open sea-valve to allow water to get to the impeller. Shut off sea-valve so if it takes some cranking to start water wouldn't get sucked into the block.
2. Turn on the battery switch(s).
3. Put the shift lever in neutral.
4. Throttle at low.
5. Hold the decompression switch and spin the engine about 30 seconds (I'm pretty sure he said 30 seconds but that seems like a lot to me) Do it again. This oils the internals before the engine starts.
6. Pull out shutoff lever and push back in. (Does something important)
6. Put throttle to full
7. Engage starter
8. When engine starts reduce throttle to idle
9. Open raw water thru-hull (promptly)

He also said:
Use only 15w40 oil
Mix coolant 50/50 before filling overflow tank. (Pouring in water and coolant separately does not mean it will mix properly in motor)

I had to write this down before I forgot so I figured I would post it here in case anyone has any personal experience to share.

Re: Volvo 2002 season startup

Sounds like good advice... years ago we installed a new 1984 2001 Volvo diesel in a repower.. It was a very loud engine and I was shocked at the mechanical 'bang' sound of the firing stroke. We thought something was actually hitting internally but it was 'normal'...

The 30 second thing sounds long but it will get things lubed up nicely. You'll probably end up doing a bit less. The most important part here is leaving the RW closed until it actually fires.. if RWC you really need to be prompt once it starts.. if FWC it's not quite so urgent but the sooner you get the seacock open the happier the impeller will be.

Thanks for the warning. It will help my heart a little to expect it.

I am sure you may have got this around the wrong way.

For the cold start procedure, you should first set the throttle 2/3 to 3/4 and then pull the stop out and push it back in. This sets the fuel supply to "excess". As soon as the engine fires and runs, the "excess" setting reverts to normal running.

I have the VP2003 in my boat, and only use the cold start procedure for cold days (when else?).

Before getting my engine "top end" overhauled, I had to decompress and turn the engine over for about 15 secs to get some fuel and oil to improve compression. I then reset the decompression lever to normal and (usually) the engine would fire after about 5 secs. Eventually, it would not start at all - hence the overhaul!

After the overhaul - glazed bores, worn rings, burnt valves and seats, blocked water injection elbow, injectors overhauled (only one out of the 3 were spraying) - the engine now starts quite often without the cold start procedure.

I have copied this post from starting problems vp 2003 [Archive] - Yachting and Boating World Forums

Quote:
Volvo cold start procedure is to open the throttle to half way THEN pull out and return the engine stop. I understand that fiddling with the throttle setting after pulling the Engine Stop resets the system.

Hi, you are correct, that is what the instruction manual says. However, once the throttle has passed the halfway point the cold start is activated by pulling and returning the stop button. If the throttle is not moved it will start but at a higher RPM. This may not be good practice but some engines require this technique-my one did.

regards,
Philip.

Re: Volvo 2002 season startup

As a matter of interest, do you have a prop shaft to prop, or sail-drive?

The reason I ask, is that there have been serious failures of the drive spline from engine drive plate to gearbox.

Here in the UK, our remedy has been to have a "hex" modification to the drive shaft/gearbox.

regards,
Philip.

Re: Volvo 2002 season startup

I have a 2003t.
There is no decompression on my engine.
Start up procedure in my owners manual says, set throttle to full, pull fuel shutoff out for 10 secs then push back in. Crank engine and throttle back when engine starts. My engine starts in seconds every time and it purrs like a kitten. You need to be ready to throttle it back so it won't over rev.
I fired it up back in march to go out for a saint patty's day sail for the first time of the season and it kicked over immediatly.
I think playing the game w/ the sea water seacock is a cooked impeller waiting to happen.
P.S. These engines are reported to be the worst engines volvo ever made.

Re: Volvo 2002 season startup

Thank you all.
I followed the directions exactly and the motor started up perfectly the first time.
Took about 5 seconds of cranking.
I couldn't have been more surprised.
I wonder if there is an inverse relationship between what you worry about and what happens.
