V8 D2 without oil cooler

[ballbag]

My noisey low comp 4.0L 99 D2 has an oil cooler.

IIRC some vehicles (D2a?) were delivered without the cooler.

With 82 degree thermostat, my engine always runs below 90C, down to 82C on the overrun.

I have a high comp 4.0L in the shed that I might put in it. I don’t know if the fuel and ignition maps differ for high and low comp engines but I’ll run it on the existing map anyway. I’m guessing it might run hotter (too much advance?). That might be ok by me as water temp is not hot enough for cabin heater to function properly at present.

Anyway, the oil cooler inlet/outlet ports have been blocked on this engine with chemweld or similar. I’ll try to clean that up and block off with threaded plugs instead.

Wow that's a long oil filter!. Is that a Z9 or similar. Be careful with long oil filters If I recall correctly not a good idea as on extreme articulation they can be hit. The correct oil filters are shorter.

Yeah that was on the engine when I pulled it out of the donor vehicle. That and the chemweld contribute to the short odds I give this motor of blowing up quickly. History is questionable at best!

People often try to save a penny and use Z9s when in fact the correct filter is not that dear

Run the cooler,, and one of these,,
I'm going to stick one on my auto cooler lines.

Good practice to fit an oil temp gauge as well if running one of those.

So Pedro/Craig, where is the best place to fit it within the lines, remembering Pedro has a V8? from memory, and me a pair of oilburners?

Ironically, I could not buy one when checking some time ago, and the first link I found today was in Perth.

In your case probably half way along the td5 engine block / sump ,between the 2 clamps which is also where the lines run together for the transmission .
Pedro wants to use it for engine oil cooler on the V8, I assume.

Thanks Craig. So is this on the return line, or as the hotter ATF initially leaves the transmission for in my case en route to the front mounted oil cooler?

Rain just arrived in Freo 10 minutes ago and belting down.

uses both lines, and will shut off 90% of flow to cooler until the thermostat opens

[Pedro_The_Swift]

in my case for the auto,,

but it does pose a question----

Do I place it in line before the STOCK cooler?
or after the stock cooler before the 2nd cooler?

or should I put one in BOTH places?? [bigrolf]

Considering the only job it does is to enable faster fluid warm up / regulation , before both coolers
Just means it'll be working more than if you had one cooler( or not open as far ).
My assumption was based on this being an engine oil cooler thread , ( one should never assume:-)

[thai_tiger]

After the standard cooler, let it do its job and use it open to the second cooler when required, also if there is a failure you will still have standard cooling operational. My Humble opinion.

May be OK , but with an extra 10% going through the second cooler there's a strong chance when not towing on a winters day in lock up of running too cool, and you might as well , if you're going to the trouble of fitting one , use it for warming the oil quickly .
Yes ,you're introducing another potential for failure by fitting one in the first place, but if you've fitted a larger / twin cooler set up along with an oil temp gauge/ warning , because you tow heavy stuff on hot days then you're better off .
There are pro's and cons , but if used with a larger cooler, and are in high load / low speed situations in hot weather, towing heavy, out of lock up a lot, OR, live in a cold climate then the pros have the heavy end of the scales

[ballbag]

So, anyone know what the factory units have instead of two dollops of chemweld?

[Pedro_The_Swift]

I think just plugs,,, hmmm...
