I have a WR1 it seems that the oil is too hot I have a defi guage set and they show it at 120 (110 on a run) degrees this is taken directly from the sump is there a way of upgrading the oil cooler system or is this temp normal ?

Thanks

A bit warm, but not dangerously high.... stick it on the rollers and see if it's running lean ?

i personaly wouldn't be happy running temps that high.

as said could be a few different reasons y it would run that high, but scoob tend o run warm, if needs be you can have an oil cooler fitted, i've got one on my classic due to running temps.
costs about £450 + vat to get one fitted properly.

do you need to uprate the oil pump to fit that or even add an additional one ?

Does it come from the sump and return there or elsewhere?

Do you need to put more oil in with one of these ??


Sorry for all the Q's but i may fit one too.
Cheers

lol, no probs, although it was fitted for me i understand the basic gist of it

a full kit should comprise, pipe work (metal cased, high strength, reinforced), thermostatic valve (most important bit), the core itself (bigger isn't always better), and then any fixing bits and bobs.

(someone please corect me if i call any parts up inccorectly lol)


mine (its a classic) is fitted between the front lower, and upper slam pannel (think thats what there called) in front of the rad (see pic above). The pipe work runs from the cooler, between the sub frame (hes to be slightly notched so not to pinch the pipe) and down onto the thermostatic valve which sits between the oil filter and the modene. (doesn't go into the sump at all i don't think)

the thermostat stops the oil getting too cold and only allows flow only when needed. my car runs between 80-90 degrees c oil temp at any air temp, no matter how i drive it.

there is some additional oil required due to increase in oil capacity in the core and additional pipe work.

also it fits behind my front mount nicley and not seen any change in oil temps since front mount was fitted.

Something like this should do:

Mocal Oil Cooler Kit

I've used this type of kit on Pug 205 with good effect. Quality kit at realistic prices

Tidgy

thats the thing you want, although no idea on the company, but mocal stuff is good

NUTTYNICK

I've used this company before, very good.

I split a hose before and needed a replacement, it arrived next day.

The real issue is though, why is your car running so hot? I've not heard of many cars running like this on normal driving so maybe there is an issue somewhere else.

silent running

That's pretty damn hot unless you're doing track work all the time, or your gauge/sender is faulty. Especially seeing as it's taken from the sump as well. You need to find out why it's this hot before looking at oil cooling.

What oil and grade are you running?

Tidgy

my bvad, i hadn't notice you said that temp form the sump, my temps are from the block

My classic with temp sensor at the sump drain showing temp of 80 deg C and hard driving it will reach 90 deg C max.Cruising will be around 74-76,normal city driving around 80-82 deg C.On a rainy day,oil temp will be lower around 70 deg C when car is on the move. Temperature here during mid day is 30-35 deg C.
Maybe your car has this under bonnet cover to aid in aerodynamic of the car which covers the oil sump.My car being a classic do not have this cover covering the oil sump so I guess better cooling on the move.
If your car have this cover,remove it and see if your oil temperature goes down.
Hope this helps.

What oil and grade are you running?

Thick oil runs hotter than thin oil.

New Age run hotter than Classics.

The cover Chan refers to is the under tray fitted to some Classics and New Age. Removing this will reduce oil temperatures.

Temperature measured from the gallery above #3 cylinder/nearest the turbo is hotter than sump temperatures.

Is your guage accurate? Test it in a kettle of boiling water.

A friend's Classic WRX also uses the same oil (Mobil 1 5W/50) as me and his oil temperature is roughly the same as mine.Roughly as in 2 deg C difference and he uses different brand of oil temp sensing.

Thanks Harvey,for the info, thicker oil runs hotter than thinner oil.
