*Hoses that abrade when rubbed against metal is asking for trouble

Better? I mean, you can literally see the hose cover coming apart (fuzzy) in the picture, and that's in free air.

I take it you are unaware of the stainless steel reinforced CPE hose inside the braided jacket?

I don't like steel braided exterior hoses because of their propensity to saw through everything they contact. The cloth is friendlier to other components. OEMs typically use rubber sheathed exteriors on their high pressure lines, just like hydraulic machinery manufacturers. Automobile applications are always very low pressure, though.

The steel braid is armoring. I'd use it in places where impact with rocks/debris is expected (like a wheel well or long runs along the bottom of the chassis), but I think you are better off running your critical lines in more protected areas if you can.

If only there were a steel inner liner underneath the nylon layer to protect against such a thing.

If only.

I think it's probably easier to rethink running into shit with the front of the car :)

This might just be too easy of a solution though.

Yeah, if only. Except there isn't. I'm very familiar with the line in question.

That line looks like Startlite, which has no steel.

On the other hand, the fuzziness doesn't really mean a whole lot, since it has easy-to-fuzz Nomex mixed in. It did survive being run over by a car.

I mean, so would a vacuum line.

Oil Cooler Stud Thread Sizes?
 

I have an application for this oil warmer/cooler that is not in a miata, but rather a small diesel engine. The oil filter "Stud" on that engine is 20x1.5mm and it seems most of these coolers adapt to a 3/4-16 thread. The oil filter threads themselves don't matter much to me because I can get a different filter.

Does anyone know what the thread size is on these that goes in to the block and what the thread size is on the coupler that screws in to the oil cooler/warmer housing? This particular cooler/warmer is one of the few that would fit in the allotted space I have.

I did do a search of this thread and didn't find anything relating to the thread size unless it was written out strangely.

Ultimately, i am looking to adapt to a block that has a 20x1.5mm female thread.

Thanks in advance for any information!

I'm looking for a cooler similar to what is on the miata. A sandwich type of cooler, that I can run coolant through. Not a oil block that redirects the oil to an air cooler or other. I need something small and contained such as the cooler that comes on the miata 1.8L. I just don't know what the stud threads on are these and that go in to the block. I have not been able to find any mention of this or documentation on it either.

If you are asking what the Miata oil filter thread size is, it's M20x1.5. The Miata block is tapped M20x1.5 and accepts a fully-threaded hollow 'stud'. The 'oil warmer' is then secured with a nut. The oil filter screws directly onto the stud.

This is exactly the information I was looking for. Thanks!

It will essentially cool the oil a little bit as well. If the oil is 250F and the coolant is 160F on the return from the radiator then it will definitely cool it once it is warmed up. Just the same as it warms it during the startup/warmup period.

It is on a little 20HP diesel motor. A little cooling will go a long ways, especially when there was not engine oil cooler from the factory.

Yes, it is a oil temperature moderator. It warms and cools, just like your breath.
