And this comment is important because Deano rode his in TSV. Everything I have read on deep sump / oil cooler modifications suggests that it isn't necessary. BruceK did a really good post here ages back showing actual GB oil and Engine oil temps prior to his run to the outback.
twomotokiwis The more I read your posts and blog the more I think you have to stop trying to fix something that might not be broken and just ride it? |

I have said many times…….”it is a Ural, don’t over think it”.
I have been to the to the top of Oz and back through the centre, loaded and travelling at 100kph. No issues with oil temp.

We are riding it no prob, just wanting to get her set up right to avoid any forseeable issues, heating on +22 is one of them and if this would help...just saying. |

I fitted the oil cooler from NE Ural to our 2023GU, which runs cool compared to our friend's 2022GU, he keep feeling our rocker covers compared to his on the 3 UAR. I picked up one from Ural NE www.uralne.com/oil-cooler-kit/ in the US in October for him. I also have the temp gauge that shows both cylinders, over the last three day ride both sides showed on 2.  |

For us the jury is still out.
Whilst I have the greatest respect for those who subscribe to "if it aint broke etc" and the "don't over think it" group. I have no desire to upset anyone. BUT, none of the previous well intentioned comments have much to do with the new 2022 10.6:1 engine. Or the heat it produces. Particularly at low speeds for prolonged periods. NOR under fully loaded conditions at temps 35c and above. There is very little real world testing from anywhere that suggests that an oil cooler will actually provide a cooler oil flow on a Ural. There is some data from the US but only for low comp engines. Most tests use CH temps. Not oil temp. Yes, I know one is a reflection of the other. If someone wants to use the CHT sensor on the right cyl head, and a scan guage to read it, under condition xyz and repeat, with an oil cooler. That will be a first and great step forward. Then repeat again in extreme conditions. Only then will we have some real evidencial proof of function for the 2022+ Ural, and whether it does
overheat (given correct operating parameters are followed) There is a term in the auto industry for this type of dynamic analysis, but it escapes me for now. (Finite analysis??) I think. Millions of $$ R n D which Ural don't have. It is conducted on almost every vehicle to determine every component is fit for purpose. Does the oil cooler work with the current oil pump?? Who knows, Does the extra oil volume help?? I live in the cooler southern regions. But, will be watching my CHT via my scan tool as Summer temps gets closer. 173 degrees = Mil light. Those living further North may like to engage in a similar exercise. Then we will know with more certainty if an oil cooler makes a difference on the 2022+ engines.

All good thoughts H and maybe useful would be the oil temperature pre and post fitment of a cooler. Cyl head temps taken at the same time as oil temps may be an enlightening factor as well to determine just what effect oil temp has on CHT. ………I suspect not much but am interested in the data.
The oil temp certainly has little effect on the oil itself given today’s quality oils unless it is getting to extreme temps.

It was very interesting talking with Bruce, the 22 onward engines he said have an upgraded oil pump, also oil squirters to the piston under the crown, I can't remember if they were new or just enlarged for 22 onward.
Personally I don't think it will make bugger all difference to CHT under load but the law of averages says if the base is cooler then it should help the overall heating aspect.
To fuel these girls up will make the biggest difference and that is a whole new discussion 😁
So, as we are heading north into heat we have decided to get the cooler while she is still a youngen, to that end we would be very happy to help with real world data if we can.
Tomorrow (Christmas day) we play Santa at Field National Park taking kids (and big kids) for a sidecar skid so than will be entertaining 👍

Unfortunately, most folks don't do much real world testing BEFORE tossing an oil cooler on. After that it is seat of the pants. Like you I would love to see the corelation between oil and ch temps. You don't happen to know where dip stick style temp guages for Ural can be had, do you?? We have half the equation resolved through the temp sensor. |

Infra red on the sump will do.
