Pajero Owners Club of South Africa

I am busy doing my first self service on my Pleasuro 3.2 DID. A note in the owner's manual raised a slight concern which I hope you experienced okes can help me with. The book says the engine oil cooler capacity is 1.3 liters. Now I am changing to Castrol Edge and would like to be sure I got all the old oil out. Question: Will the oil cooler drain normally through the sump plug or is there a special procedure to follow such as the one for the gearbox oil cooler?

Hi Bigwill,
I recently drianed my oil cooler with a siple method.
I took a compressor and installed a normal ball valve in line to controll the air flow and put the rubber hose over the oil cooler pipe and virtually blowed all the oil out.
Just be carefull for the oil blow in your face .I put a old t-shirt torn over the outlet and with controlled airflow drained the oil into a skottel and whola - cleaned. you can after all oil is out open air to max to blow out all oil.
Hope this helps.

Thanks Paw, that is an interesting way to go about it. Thanks also for confirming then that not all oil can be drained from the sump plug.

Boer maak a plan!! You probably pay the dealers huge bucks for the same technique

How sure can one be that the dealers do go to this extent to avoid contaminated oil remaining behind and gets mixed in with the fresh oil? In some cases I suppose even incompatable oils could be mixed together. (This is what I am now trying to avoid). I thougt of using engine flush, but again the flushing agent will also remain behind in the cooler which is also undesired.

I've just now measured the oil that drained out. It is just over 8 liters, which only accounts for the contents of the sump and the oil filter. Another 1.3 liters are still trapped in the cooler.

Paw,

Am I right in saying you have a 3.5 petrol engine, which do have an engine oil cooler. Well I have just done some stripping down to get to my 3.2 DID's coolers and all I find behind the grill is the turbo intercooler, the radiator, the aircon cooler and a gearbox oil cooler. I do not find an engine oil cooler at all. Please will someone confirm to me that the 2004 DID model does not have an engine oil cooler and that I may now give up on this wild goose chase. Why the owners manual states an engine oil cooler capacity figure in the specifications section for the diesel engine is still beyond me. Can someone also please confirm to me that the engine oil replacement quantity is about eight and a half liters only.

I notice a number of speculative posts on the forum regarding parts replacement and lubrication...

Can I suggest that people have a look at the workshop manuals in the documentation section...

It is my one mission that this forum be the best repository of pajero related documentation on the net. If you cant find the right info... I am failing in this regard.

The 4m40 (2.8 TDi) and 4m41 (3.2 Di-D) engines have their oil coolers mounted to the engine block:

Hi 4ePajero,

Now that clears up the issue for me. One can thus assume that the oil in the oil cooler will drain out with the rest of the oil in the sump and the oil filter.

I have not yet managed to get Simon's Gen3 workshop manual loaded into a usable format. I get an error message about being unable to update my directory. However the 4m40 manual is readable and I can see from there what you are showing me in your thread aswell. Many thanks for taking in interest in making my life a little easier. Isn't that the beauty of a forum like this?

I have never worried about the residual oil in the oil coolers (I have 2!).
According to Castrol, Edge is compatible with other oils.

While we are talking oil change:

• Mitsu oil filters are cheaper from the dealer than 3rd party
• make sure you remove the old rubber seal with the old filter (I once forgot, and ended up with most of my new oil on the floor!)
