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

      My BMW E39 528i touring

      By PranK · Posted

      The new project has arrived. I have wanted one of these for such a long time, well before that meathead Clarkson drove one in Africa. I really wanted an E34 but I have some medical issues that mean I *really* can't bump my head and the lack of airbags in the E34 made it just too big of a risk.  I don't know why I've always liked these older touring BMW's to be honest, but man I love this car. She's been pretty well maintained for her 243k's with what appears to be only a single oil leak at the oil filter housing gasket. It has a bunch of updates including later model bumper and headlights, 7 series billion-way adjustable seats and it came with a few spares and another set of wheels with legal tyres. I got a unregistered car permit from the RTA and drove it back from Canberra on Saturday.                   First cab off the rank is cleaning it up for blue slip. I dont know how picky they'll be but I figured I'd clean the headlights, fix the oil filter housing gasket, replace the speed sensors (throwing errors) and swap the OE wheels (the M Sport wheels have a big chunk out of one of the tyres.) I also need to replace all 6 gas struts - 2 for bonnet, 2 for hatch and 2 for hatch glass. The car tries to eat me whenever i open any of these. My plan for this car; Ultimately, this is a budget car. I can't afford to throw lots at it and its because I have another car that I got this, if something breaks its no big deal. I will just maintain and repair it really. But eventually I want to do a manual conversion. It actually looks pretty straight forward for E39's and the trickiest part will be sourcing the parts.  I do need to replace some suspension arms or bushes because wow, she's a floaty old girl. She's also fantastically slow. Like really, really slow. When pulling back out on to the freeway on Sat after a quick pull over I needed to wait until no cars were visible before going.  Oh, and the guy I bought it from had a gorgeous R31 GTS-X in the garage.

      R33 gtst gearbox top barb

      Do you have a picture? I assume it is a breather for gearbox oil as it expands, it should have a vacuum line run nice and high in the engine bay (R32 GTR has it on a top bellhousing bolt)

      Hi all, I am putting an r33 gtst gearbox into a VL and have noticed what looks like a vacuum barb on the box (on top in the middle). Suspecting that it's a vacuum line but I'd like to double check, if someone could confirm the function of that would be great. Cheers in advance.

      I’d love to find some where that can recover the dashes to look brand new and original. Mine has a very slight bubble, nothing compared to some I’ve seen though

      $170K. I asked one of the guys there as a joke if that price was just for the passenger seat as it was where the price sheet was... he tried really hard to crack a smile 😄 He also mentioned that every single part of the car was inspected and either restored or replaced with a new or as new part, or made from scratch. The interior was incredible, every inch like a new car.
