I have read up some article on Turbo car maintenance. One of the point is to allow the Turbo to warm up before pushing it and also allow it to cool down after driving especially if you push hard. It is recommended to leave the car from 15 seconds to 1 minute before turning off the engine. This is for lubricant to continue flowing to cool down the turbo.

It is said that a Turbo Timer will do the job to cool down the turbo even after we switch off the engine. Does 308 THP have a turbo timer built in?

If I'm not mistaken, after a long hard drive, after switching off the engine, I can hear something like a fan is still running. It should function to cool down the turbo right? If not, what's the best practise to cool down the turbo?

What you read applies to Japanese Turbo cars. The 308 doesn't need a turbo timer.

It has a water pump for the intercooler that detects the temperature of the engine when you shut it. If its hot, the water pump will continue to let the water flow and cool the engine/intercooler. Also, if its too hot, the fan will continue running.

This is the latest technology in Europe where the Japanese still need the turbo timer... Turbo timers are the thing of the past!
Its not what you have...... its how you use it!!

Alan,


I do understand that the water pump is on demand from ECU but one of the main purpose of Turbo timer is to get the Engine oil flowing on the turbine bearing..So, the water pump and fan is for the water to flow through the radiator to cool down the engine and I think it is still advisable to let the engine run for 15-30 secs to let engine oil flow through the turbine bearing..smile.gif. Better be safe marrrr...kekkekekekekekekekee..Prevention better than cure...Use of good engine oil will help..smile.gif

In this case, if the engine oil pump is on demand from ECU, then it can be just off right away since the oil pump will still pump engine oil through the turbine bearing when it is too hot...smile.gif

My 2 cents oniiii...smile.gif

Cheers

Chargerguy,
From what I've been reading, the new PUG/Mini engines uses both oil and water for cooling. When the engine is shut off, an auxillary electric pump continues to circulate water and cool the turbo.
seriously though...modern turbo's are oil-cooled and as said above, there's no need for a turbo timer to run the car after driving it to keep things circulating. Excessive heat is death for a turbo....manufacturers know this and have designed the cooling systems to properly cool the turbo down with the ignition off.
Don't you think BMW/Peugeot have thought about this problem?
Its not what you have...... its how you use it!!

They definately thought of this problem and it is very mature technology but better be safe than sorry marrrr...smile.gif I kena once with Bimmer diesel turbo and Merz diesel turbo as well...sad.gif

Sometimes when the temp is too hot and the engine oil in between the turbine shaft unable to dissipate heat and circulate it fast enuff, it might fry it. This is just my opinion and my practice when dealing with turbocharged car..

Nowadays, I let the engine to idle for like 10-15secs on Prado Diesel after some long journey drive..I did not install any turbo timer or so, just switch off the car later..smile.gif If drive slowly and short distance, I just switch it off within 3 secs...

Bro, its good practice if you are skeptical. No harm if you let the engine run a while before shutting it off. However, as much as we all love our PUGS, I would believe you don't need to do so. That would be my practice. But, seriously, if you wanna let the engine run for a little while longer... you are right too... smile_thumbup.gif

just wanna get some opinion from the members. my THP is due for 2500km inspection service nx wk and i've made booking @ glenmarie. i understood that it'll just be an inspection however does any of the member here change their engine oil too? do u think it's necessary?

i intend to go to the pirelli tyre shop nearby SC as suggested by alan after the service for alignment, to get rid of beyonce.

hah, in my honest opinion, you don't need to change the oil. Its recommended to change at 10K, however, in certain countries, its recommended to change at 30K. But due to the weather here which is hot, 10K is better.
However, at 2.5K, you don't need to change the oil. But if you feel rich and kiasu (joking ar.. don't angry).... there is no harm by changing the oil & oil filter, although I wouldn't think its necessary as its stipulated in the service recommendation.
