Hey guys,
Anyone run an ultragauge/scangauge and noted the running temp (coolant) of their 2.2? Mine sits at around 92-96 degrees on the motorway, around 90 on slower roads. Bit warmer than my 2.4 was and bit warmer than i’d have expected. Been like that since new though, never overheater or anything and never hit 100 even. Anyone else notice similar temps? I was under the impression most cars ran at 80-85 degrees. Cheers, David Land Rovers of all shapes S3 onwards… Daily is a 110 V8. |

2.2. Highest 96, lowest 90.

David, 85°C running temps are a long time ago now. Manufacturers have increased that, mainly for emission control reasons, not really because it is better for the engine though. I personally doubt that coolant temps in the mid 90's are better for an engine than if they were in the mid 80's, rather the opposite I think. And if you would have coolant temps under normal conditions in the mid 80's, it surely gives the entire coolant system more margin to keep it all in check in case of any type of engine stress situations (very hot outside temps, heavy load on engine, etc.) where coolant temps would naturally go higher. I'd rather have a coolant system which fully opens to its max capacity already already well under 90°C, than only at something close to 100°C....
One of the answers to this is the PEL500110. It has been discussed at length in below thread, and many have installed it, never heard any negative feedback later. Top of my head, the standard Puma thermostat (cream colour) starts to open only at 88°C and is fully open at about 96°C, while the PEL500110 thermostat (grey colour and the original thermostat on the D2) starts opening at 82°C and is fully open already at 88°C. This PEL500110 works for both 2.4 and 2.2 engines. Happy reading, it really is worth the 9 pages. You can then make up your own mind.

^^ I think something would really be wrong with your motor if "when loaded up and pulling a grade at 50°C" outside temps your coolant would not exceed 82°C.
Now, those 50°C outside temps..........., when was the last time we had those here again?  You never actually own a Defender. You merely look after it for the next generation.

My 2.2 runs between 93 and 97 on fast roads. Occasionally hits 99/100 on hill with trailer so I think yours is fine.
About 18m ago it was running a bit higher but a new thermostat (cream) sorted that. Since fitting the ultragauge I do find when towing using 5th rather than 6th gear on A roads keeps it cooler |

Hi David,
I found the same when I changed my 2.4 Defender for a 2.2. I found there was a slight increase in running temperature when running over the same roads when using the 2.2. My local Ford dealer put a slightly thicker coolant mix (my diagnosis as it seemed "thick") into my Transit after a hose replacement which increased the running temperature in my 2.4 Transit van by 5 degrees Celsius. As I was not happy with the service I was receiving I changed dealers and asked them to drain and refill the coolant system with the correct mix. Problem solved and now runs correctly. |

My 2.4 ran a bit hotter with coolant concentrate and water mix that was shoved in.
Since I've ran pre mix, it's ran a degree or two cooler at an estimate. Across the board. $W33T $0U7H3RN $UG4R 🇬🇧ðŸ´ó §ó ¢ó ¥ó ®ó §ó ¿ðŸ´ó §ó ¢ó ·ó ¬ó ³ó ¿ðŸ´ó §ó ¢ó ³ó £ó ´ó ¿ðŸ‡®ðŸ‡ªðŸ‡ºðŸ‡¸â›½ï¸ðŸ›¢ï¸âš™ï¸ðŸ§°ðŸ’ª |

Thanks for the advice as always guys
Nothing to worry about then, just a difference Cheers, David Land Rovers of all shapes S3 onwards… Daily is a 110 V8. |
