Izuzu 42 service intervals

[DandGNWales]

Hi, If the river trent gods smile on us we hope to get the boat lifted on 11th for the pre purchase survey, so thinking ahead and trying to get my ducks in a row, what is the service interval hours wise for an Izuzu 42?, I got 250 hours in my head but no idea how it got there lol

[LadyG]

I've got an Izuzu 33 and had the same problem. Lack of info.

I found a boat fitter guy who had a booklet on the 500hour service, i think, well so he said [cynic, moi?].

So I reckon 250 is fine as long as you use the proper materials.

Taking over an unknown engine, best to change oil and filter and start from there with your 250 and 500 hour service.

Dont forget the gearbox. 

The engine mountings need to be checked,  my boat is 25 yo and I think it has had one mount replaced.

It is quiet and  has had an easy life.

Thanks Lady G for a great reply, she is only on 500 hours so planned on oil and all filters (genuine) and belts, not sure if valves are shims or screw and lock nut but if they need doing will get them checked but she does sound very sweet with no smoke so want to look after her.

Done the above on my 42 for the last 18 years with no problem at all.

I've never completely changed the coolant, but before I knew the correct level. I kept topping up with a Universal stuff, then realised the level is naturally near the block in my case, as determined by by a little rubber overflow hose. It rarely needs any top up.

I get a guy to service the engine and do other bits and pieces once a year.

I can't reach the gearbox. The first time this was addressed there was 0.6l of black treacle removed, maybe after 20 years!,, the gearbox thing was drained, magnetic sump plug wiped, and then topped with 1 l Dextron2 . Depends on the gearbox of course.

I just potter, but if hard driving the beast I would be more fastidious. 

Any  change in the engine would not be ignored. Other than that, I go for minimal interference.

Thanks alias for posting that, same as my guess, better do the lottery this week lol. When we had 2 x Perkins diesels in our salt water boat, we got genuine filters cheap from parts for engines, is there a dark secret for genuine izuzu filters don't think they break the bank, but if I can find a good supplier for regular use

I dont think you need worry much. I keep spares of oem, but these days I don't think it matters much.there is a firm which only sells filters, filters.online perhaps.

From the HMI Isuzu manual:

Very confusing service schedule, it implies an oil and filter change every 50 hours which is ridiculous. I suggest a 250 hour service interval with the extras at 500 hours only.

That was my take on it as well and that is the service plan I will adopt and see how it all pans out

The key words there are "After first 50 hours", so that bit of maintenance is only intended to be carried out once.

No, it includes the 50 hour service with the 250 and the 500, read it again please before posting. I am well aware of how it is supposed to read but it does not.

Well, I read it exactly the same as @alias. "After first 50 hours" means just that - after the first 50 hours, not every 50 hours. You will also note that the next two lists start with "Every xxx hours", but the 50 hour one does not.

 

Anyone with any experience would also expect t see such instructions for commissioning and running a new engine.

 

However, it is still badly written because after the first 50 hours I can see no mention of oil changes.

[PeterF]

That because for 250 and 500 hours it says do what is listed for 50 hours plus some extras so it gets the oil change by incorporation of the 50 hours.

Thank you PeterF, I knew I read it correctly even if it is written incorrectly.  Some folk are too quick to contradict on here before they have comprehended a post. I would not be changing oil and filters at 50 hours!

My bold.

 

So you think this does not contradict this:

I will not argue with you but please read that the 250 and 500 hours are to include the 50 hours. I know it is wrong but that is what it says!

[alias]

I suppose they could have listed all the elements of the "after fifty hours service" under the 250 hour interval, and not mention the "after 50 hour service" under that heading.    

 

OK it isn't written as clearly as it might be, but I see nothing there implying a service requirement every 50 miles.

I agree, I must be blind, not to see that.

You are wrong.  It doesn't.

The trouble is coolant loses its anti-corrosive properties after a few years (generally 2years for blue and 5 years for red), so the inside of your skin tank and various parts of your engine may be rusting, especially since the engine is made from dissimilar metals in contact with each other (galvanic corrosion) immersed in an electrolyte (old coolant & water). 

 

If you can't be bothered to flush it out and change it (and it is an expensive, messy job) then at least chuck some Ankorsol in there. Although it's expensive you only need to add about 2% by volume of coolant and it mixes easily.

The older pre-HMI-blue Isuzus (3KR1, 3KC1 etc) specify a 100hr oil change, it seems that the HMI marinised ones lengthen the interval.

I think the guy who did the 500 hour service checked the strenghth,  he certainly drew off a couple of litres., it was pink, and clear. I have put about 2.5 l of Universal stuf over thevlast year.

.I've paid for a major service, I can do no more at this time.

I'll buy some Ankersol if i can, but is it going to be better than Prestone which also claims to be great stuff.

Its not a case of I can't be bothered, its a case of I pay someone to do what he considers necessary. He has the T shirt, not me.

No. The 250 and 500 hour services are to include the items listed for the (once only) 50 hour service.
