European models of Hilux have a “power heat” button that raises the idle, they have an electric heating element in the heater box that is to ensure heat is available from the heater during start up or long idle periods at cold temperatures, this cuts off when the engine reaches about a quarter way up the temp gauge and heat is available from the coolant. The idle is raised to help the alternator cope with the increased load. This is a great feature in the winter for de icing/de misting. 👍🏻🇬🇧
I would always use the idle up button and warm the engine for 2 or 3 minutes before driving . The while point of raising the revs is to get sufficient oil around the engine as quickly as possible . I normally drive vehicles that are two shades off being a knacker and I've learned every trick to keep them running as long as possible .
If it takes two or three minutes to get the oil moving around, you’re in trouble, the oil is in the whole engine within seconds. And yes, that is when engine damage happens in the first few seconds. If the oil quality is not right this talk of minutes is ridiculous. To be quite honest. I’m sorry.
As an oil burner diesel is spaying /sucking diesel oil into the cylinders on the pre compression stroke and you also got engine oil at the crank/sump side too, you are getting lubricant both sides of the pistons. when the Diesel engine is cold starting it is going to wear less in the cylinders than petrol engine. Like AJ 👍🏻🇬🇧said in the comments 👇🏻 the turbo don't like no oil but they are a consumable items now on most cars lucky to last 80k on short drives, better to leave the engine idle to cool down before turning off to save turbo. I was told by an importer of Japanese cars into the UK that the idle up was for the Japan's market. He said that they gets lots of low mileage 4x4 from Japan but they have been sitting Idling for a long periods of time as they were used for heating houses in the cold mountains of Japan. because houses in Japan have little or no insulation and no main town gas only expensive electricity and LPG to heat. People used to connect the cars water cooling pipes to the house wet central heating systems and would heat the house via the cars engine. The increasing revs would make the engine run hotter to warm the house. That was what I was told this in about 2006, can anyone confirm this? Do not think you could do this with a DPF now. The Power heat in my UK hilux is great with the aux electric heater but it is the model with the twin batteries set up so not too much of a drain.
Haha yeah I’ve accidentally pushed that button in while cleaning my prado and wondered why it was idling higher than usual when I started my car - it rarely gets below 5°C in QLD 😅. I’ve honestly never had to intentionally use it
Okay boss,I’ve been driving petrol cars for ever now and a newbie to diesel (NT Pajero, you’re probably not keen on them!?) should I be warming up on idle on a cold day before driving or not? Certainly feels dumpy when it’s cold but having just taken a 500,000 km commodore to the wreckers it ain’t the same. Should I think differently? Edit: or did you just answer the question in the video and I’m too dumb to have noticed? Have a good Sunday.
I’ve been driving diesels since God was in short trousers and all I do is give it thirty seconds after start up to let the oil get round the turbo then I’m on my way I never Labour or thrash a cold engine and I’ve never had to replace a turbo, hope your Pajero give you as much service as your Commodore did 👍🏻🇬🇧

OEM part number 094800-0370 👍🏻🇬🇧. Thanks I never knew for sure.
What?
I always wondered what that button did. cheers

@Fourby4Diesel with respect, I didn't say it takes 2 to 3 minutes for the oil to get around the engine . Warm the engine , is what I said .
It also uses heaps more fuel if used regularly.

Yep, agree, dont need idle up in Australia
Water hammer engaged
66000km?
Hardly bloody driven
