Car just seems to be running hot?

[Jon]

Start the R up & from cold - leave on idle for less than 5 mins
and the fans cut in, put you hand over the exhaust gosses coming out
and they are surprisingly warm/hot?
front mount/fmic oil cooler fitted - bizarre?

any ideas?

Simple one - have you checked the coolant?

If the coolant is ok then you could have a failing water pump so check that out too...

wish it was that simple paz
coolant spot on
full rebuild last year i had a brand new water pump fitted Rishi
how do you check a possibly failing one ?

even though i have a fmic & front mount oil cooler i have noticed that
the oil temp is higher under high boost lately :?:

 

[paz]

:lol: Shame, I've done that myself before now

Good luck sorting it

When the stat opens you'll be able to feel the preasure from the pump pushing the coolant around....

Check at the thermostat is opening too...

Take the rad hose off and turn the engine over when cold... You'll soon see if the water pump is flowing water though once warm...

Check the original oil cooler water pipes at the back of the block. Mine split yesterday and caused the same symptoms.
BASTARD to change to :x

 

[Dooie Pop Pop]

when you say 'coolents ok' im gonna assume you mean the rad itself and not the expansion bottle

it should only take 5mins to get the water hot at this time of year anyway. siezed thermostat? have you changed the water recently? you might have an air lock.

 

[Jon]

deffo rads ok, and i know the thermostats fine as i fitted a more precise
coolant temp gauge & it goes up & down like clockwork when im driving
about, never goes over 85 even flat on motorway driving bursts

hmm,ok thats plenty to go buy then chaps!
thanks for the help people

do you have air con is it on all the time , the air con brings the fans on. my fans dont cut in till temp hits 95.normal driveing temp on mine 85ish in slow moveing traffic it rises to 90 /95 then fans cut in . have tried this on my drive way cuts in at 95 switches off at 92 i thought this was normal :? do i have a problem. :roll: :roll:

If it's sat idling, there's no airflow through the radiator or engine bay, the fans will provide the only cooling airflow, so I'd expect it to be hot :?

 

[Jon]

nah fastguy
its only got like this lately :?
car could sit on the driveway for 1/2 hour and still the gasses out the exhaust would be cool, fans wouldn't come on for at least 20 mins
even with the fm fitted oil cooler, the oil temp never went over 80 ish (on idle & slow cruising)
now it goes straight to around 90ish after about 5-10 mins on idle

 

[Jon]

me's thinking maybe my choice of oil
friction & heat?
i'm using Castrol RS 10w 60

try a new 1.3 rad cap had the same problem and now its stoped i fitted a new nismo 1.3 of pressure now its cooler and stoped over heating

hope this helps

 

[Jon]

hmm - could be worth a go..cheers chap
