I Have A Problem And Don't Know Where To Start

[Jimmy_8472]

Hey guys,

just throwing this out there because i'm not sure what to do.

Just before Christmas i was driving home from work and my water temp gauge started spiking above normal along with my oil temp gauge with went just over 100 degrees.

i thought maybe the coolant or oil had run a bit dry and it was around 7000 k's since i did the last service, so i serviced it again, new oil, filter and coolant. and all seemed fine again. except i just got home from my brothers place and it's happened again. the water temp stays good for a while as the oil temp slowly creeps higher and higher even just cruising at 80kph then when the oil temp gets just over 100 the water temp spikes....

Could this be a turbo problem maybe?

Any ideas, or possible things to check would appreciated.

Thanks.

taking a bit of a punt here, but have you checked your thermostat? Seem to remember hearing that can be a possible cause, might be worth doing a search on that as well.

[Jimmy_8472]

Maybe, but i changed the thermostat just under a year ago. it seems whatever it is, is causing the oil temp to go up first..

It's probably worth mentioning that there is was a couple of little backfires from the exhaust while the car was warming up before i left the house.

maybe need to check the plugs...?

water pump on its way out? when did u change it last?

[Sinista32]

Your on the right track. Read this it may help Link

and yep wouldn't hurt to check your plugs too. Buy the cheaper copper ones

In summary - Water/oil temps are related and should generaly be around 85 degrees for normal driving

[Jimmy_8472]

Thanks guys, all sorted.

i put a bigger better radiator in and it's been fine since.

noticed a slight leak from the water pump too and installed a new one last week.

Now it's purring like a kitten again

I've got the same thing

But also my heater is being a bit funny, so I'm gonna try to blast out the coolant heater pipes that go through the firewall making sure there's no blockage in there. Then move onto a just jap radiator....

Good to hear its all back up and running.

How much did the radiator end up setting you back if you don't mind me asking?

Have a look at the NSW member's discount thread on radiators, they actually look pretty damn good man

Exactly

I just went to Phillip radiator service and got a brand new GTR radiator (Core is twice the size of standard) and it was around $270.

i would have done a little shopping first but it was between Chrissy and new years so many places were closed and i needed to get it sorted quickly.

Just out of curiousity Pat, what does your oil temp reach when driving normally (before you were having this prob)

It's just that mine is stable now but it settles in at around 92 degrees which is still slightly higher than i'd like it to be..

[Randon_I_Am]

It used to sit just under the second line, around 85i would guess. That's where richards sits at the moment.

did you have any problems with the heater being a bit funny?

[Jimmy_8472]

not really

it just likes to sit on or just above that line.

could be the oil i'm using.
