Engine temp issue after intercooler fitment

<< < (2/3) > >>

stageonesimmo:
It will be the restriction of the full width cooler showing up the fact that your old rad is not quite up to it - take a good look at the fins - I'll bet there are a fair few missing or barely hanging in there, plus it will have 'furred-up' internally - you could try flushing it with some cleaner and see if that helps, but the best bet is to fit a new one.  Or as above - go for leccy fans - I'd favour the big 'blow' ones off a pug 405 or some such - they could mount on the front of the inter-cooler and if switched manually you could bang en on when towing and it will actually increase the effect of the inter-cooler - not by much, but it will, and that will help to keep exhaust gas temps down when you need it most.......

Magnum335:
Its a sign that your rad isnt working at full efficiency.
I had one fitted last year and it has done some HEAVY towing and the temp guage hasnt shifted.

mmgemini:
That full size intercooler isn't any larger than an air con radiator. Or a gearbox oil cooler on a Wolf. They both work in temperatures a lot higher than th UK

philbert:
i fitted a full size allisport intercooler to my tdi 90.
the problem i had was it wouldnt heat up at all it always ran cold
which was great for power outout but not for driver comfort!

stageonesimmo:
Mike, gotta disagree with the WOLF tranny cooler comment - they are titchy in comparison to a full width td5 style inter-cooler in evvey dimension except maybe thickness...................

But lets not fall out over it eh?.......... :wink:
