Mechanical Oil Temp

[river_clan]

Greetings,

Caddywumpus was kind enough to introduce our Samurai TD conversion to the list, and he said this was THE place to find answers!

The BioZuk does well cooling wise, until it is doing 60-65 on the highway for extend periods, and then the fans kick on.

I'm trying to troubleshoot this, as it seems like the last bug of the install. I am installing a new VDO water temp gauge and sender, but also wanted to install a mechanical oil temp gauge. My thought is that maybe I can add an oil cooler for those highway speeds and pulling a trailer, and want to monitor it. Bummer is, the VDO white cockpit gauges have no electrical  oil temp gauge available, and I already have the others in this set. <sigh>

Anyhow, to get to the point, where can I mount this @#$ mechanical sender? It's big, won't fit in a 10mm, and appears the smallest bushing adapter I can do is 13mm. So... I was thinking, what about that plate on the side of the block near the oil filter housing? Could that be drilled and tapped for a sensor? I hate to drop the oil pan to add another hole, and being an offroad buggy, wires by the oil pan seem like a bad idea.

What's everyone's recommendation on oil coolers? Sandwich adapters, or tap out the oil filter flange?

Thanks!

Looking at that pic, I see one inlet/outlet and a plug. Would you be so kind as to explain the flow, and where would be best to drill and tap? I'm using an angled housing.. but I think it's pretty close for discussion?

Mabye a Volvo 240 turbo oil cooler thermostst could be used? The oil filter screws onto this "adpter" with the thermostat. I also have to say I am not sure how the oil warmer works with the IDI motors.

Thanks for the great information!

The casting is from a north/south Quantum. I think the mods of it are a bit past my knowledge, but what a clean install!

I'd have to lose the oil warmer to do a sandwich even if I had clearance for the filter?

Thanks!

Greetings,

I went ahead and picked up a Flexalite oil cooler and sandwich adapter. We removed the oil warmer, and it's running even hotter than it was.

We mounted the oil cooler in front of the radiator. The radiator is a 27" brass/copper unit. It has (2) 1700 cfm puller fans on it, mounted between the radiator and the timing belt cover.

It was staying under 205f, even on tough 15% grades, but when I hit the highway with it, the gauge shot to 225, and I had to pull over and cope.

The real bummer is, I was on my way to get Thai Food, and had already driven over the mountains.   :cry:

The question I ask myself tonight, is what do I have to do to cool this beast down?

If I use the oil warmer and the sandwich, I will have to find a shorter filter than a Mann... if there are any.

Perhaps the tapping of the oil flange is the only real way??

Di you try a fresh water pump in this thing? Sometimes the impeller slips on the shaft and the efficiency goes out the window. Something else to remember is that a diesel is a big air pump. The more air you can get through the engine, the cooler it will run. Bigger exhaust and intake will help, as will an intercooler. Working the engine too hard at low revs (overfueled) will drive the temp up too. How high is this thing geared? Geared for pulling as opposed to top end will help, because all that extra air through the engine will help keep it cool. Just one more thing to consider. Good luck!
