Engine temp issue after intercooler fitment

(1/3) > >>

tim-green:
Has anyone had any experance of large jumps in engine temps once full length intercooler is fitted, before it was fitted the temp gauge sat at about 50% of the gauge, now at the same engine speeds it sits at about 75%, I have had the water pump changed and the viscous fan checked and they are fine, the radiator had some mud and stuff in it but this has now been blown away, great things air compressers.

Bob696:
Yeap had similar. Changed the guage and all sorts.

Now sits at 50% but goes upto over 90% when pulling up hills in 5th on the motorway or running for extended periods at over 65mph.

Guy at alisports said that it happens quite a lot and it is down to older radiators not being as efficient as they should be due to age.

Not fixed mine yet.

extreme90:
my 90 the same, bin the old paddle wheel and fit a leccy fan, brought the temp down alot
but im changing rad before the real hot weather comes as i dont want another fried 200  :shock:

Range Rover Blues:
Is this on full-width intercoolers or replacement sized ones?

Or am I barking up the wrong tree 'cos yours don't look like the Disco/RRC ones in the first place :?

unknownmanxman:
yeah, i have this problem too.. i fitted an electric fan and it helped alot!

But thinking of replacing the radator.. it just worries me.. i dont want to fry it..

Either that, or take the big intercooler back out!
