Abnormally Low Water Temperature

Hi guys,

Just trying to nut out something strange that has been happening to my car... it never seems to get up to normal operating temperature (used to get to around half way on the OEM temp gauge)

These days it only gets into that "normal" area when driven hard. For example, last night I went for a drive and in 30 mins the needle was still only sitting a few millimetres above the lowest mark...

So... things I have done to my car that involves cooling:

R34 SMIC (makes a huge difference I'm sure lol)

42mm radiator

N1 water pump

Here are my thoughts so far:

Thermostat that is locked open

Faulty sensor

My questions:

What is the most cost effective way of checking what is faulty?

If not the above two problems, what else could it be?

Any help with my problem would be greatly appreciated :)

Cass

A thermometer would be a cheap way to check. Or a infrared thermometer if u can get one to use.

Or even cheaper turn the heater on and see if its hot like normal

The heater has been running a little cooler than usual, only really noticed this recently as it gets colder :laugh:

Seems step one for me will be to be to pull the thermostat out and give it a visual :)

Thanks guys

      KW only offers a set for the R32 GTR. Popular options are D2 racing, Ksport or Öhlins. I have a D2 Racing coilover set, though I don't know for sure which one.

      Well, the good news is you have more than one very good option for new coilovers in and around your country. Worth the drive over to KW to talk about GTR stuff.

      Fair enough, I am in no way a tire expert so I'm not familiar with all the terms and conditions. I'll definitely note down the AD09 to potentially try in the future. Rain is not too big of a concern for now as I will probably only drive in the rain when I have to. And considering I still lack experience driving the GTR I'd more than likely take it easy too. I have coilovers in the car but as I barely got to drive so far I never bothered to even check if they are adjustable haha. The suspension is almost entirely old and worn as well so I suppose when I eventually fix that in the future that would make a huge difference.

      There's not a great deal to report here .... except ...... FOR .... LSD!!!  I bought a Quaife LSD from the UK and shipped it here .... Wish I'd just bought locally cause the shipping and duty was $700! But there were so many diffs used in the E90s I just wanted to be absolutely certain I was getting the right one so I spoke with a supplier in the UK who builds race cars and they have heaps of experience with the E90s.  I pulled the diff out which was seriously awesome - I've never done anything like that before, I must have watched 1000 videos on YT about it as well as consulting the Bentley manual. It was super easy in the end. The diff was delivered to the awesome folks at Hornsby Diffs and will be back in a few weeks. I also replaced the diff bushings with some Nolathane ones.  Really looking forward to getting it back and getting back to the track or even the skidpan.

      yeah... the 13kg/mm springs weren't always in there, I had 10kg/mm but doing a few SMSP commanded heavier front springs. It's so good now going into T1 and T2, just need more seat time and real tyres.
