Temp Rise After Maintainence

[andy panda]

So, I replaced my exhaust manifold gasket, and both turbo gaskets due to some leaking, and after I've bolted it all up and that yea it's running better but now the oil temp is going up 15c more than it used to. Was I meant to bleed anything on the turbo before I drove it again or something? I replaced the coolant when I put shit back together so it's got enough coolant.. There's also a new whining sound in the engine bay that I can't pinpoint, whether that's part of the problem or not I don't know...

Any advice on this would be good.

Also I went to unplug to ecu so I could reset it and noticed 1 of the wires were frayed... *gulp*

may need to bleed air out of the block

Hmm, how on earth do you do that :S I know a bit about cars but not that nitty gritty kinda stuff

Google "coolant bleed RB25" and see how many hits you get. Basically RB are cops of things to bleed. I always sit it on the dyno if I can so you can get it nice and hot so the thermostat is wide open.

Undo the radiator cap.

Idle the car for a good 10min give it a rev every now and then if you feel like it

You should notice the coolant bubble away.

Coolant doesnt boil very easily so these bubbles are air bubbles in your system.

Sit back and wait for the coolant to get nice and hot.

You could even have the aircon on full hot this will help as well

After it stop bubbling put the cap back on an enjoy

Good luck

Thanks for that guys!

ummmmmmm that aint overly correct Kasko. you need to remove the coolant bleed screws or you will never actually get all the air out.

I've never had any issues bleeding an rb using the bleed screws. Had plenty of issues bleeding ej's though.

Front bleed screw (should be one near the back too):

[andy panda]

oh cool thanks for that! i shall check all this out tomorrow when im with my car

So I bled my coolant and it brought the temp down a bit but still not back to what it was, hmmm... Whining is still there but not as loud. Any ideas?
