low temp thermostat

[sambb]

Alright I have a plan. I'll call a couple of different VW parts places and see if they carry the same part I mentioned above and then i'll just go ahead and get the much cheaper tridon version that matches those specs. When I go to do the swap i'll saucepan check the one that I pull out and we'll know if the thermostat spec has changed. I know the 06' models were pretty much first cars off the boat - I think they went on sale even before Europe got them so it'll be interesting to see what the factory put into my car.

Somethings going on though because the tridon site lists the 90 degree as the standard for my car. They just happen to also carry an 82 degree that matches what VW now carry??

The level sensor also does oil temp. Lots of Audi's have a gauge for it. Our A4 does. No idea on the block, so just start at 001 and go up.

Went out to get some last minute Easter eggs and looked at vcds. Block 004 for coolant temp and I found block 104 which had a temp that I picked up on at 81 degrees, climbed to 87 and had dropped to 85 after the car was parked for a while. I can't confirm that it's oil temp but it looked like it and unfortunately the excel log didn't give a better description of it than "temperature".
I doubt I have a 90 degree cracking thermostat. Doing 70kph in 5th for a couple of Kay's saw coolant temp ( that's head exit temp) get down to 81 degrees without too much problem. Idling it for a few minutes parked before I turned it off though saw it hit 94 and it went to 96 after I'd switched the engine off, so I do think it would climb pretty sharply after shut off at an event and get pretty hot. And this is on a 25 degree ambient night. Makes you wonder why they even have a temp gauge. More than 15 degrees of variance just in pedestrian use and the gauge said 90 the whole time.
That temp that I suspected was oil temp was basically bolted to 87 degrees the whole time I was driving - idling, a few squirts and cruising along.

disconnect the level sensor and see if it disappears.

Or start the car from cold and look at water and the random temp.

If the water temp gauge swung all place the common driver would be bricking it.

New Beetles just have a warning light that is cold and off. Then a rd one for over heat. Ideal for girls

Water temp sensing flange:

42 Draft Designs Water Temp Adaptor - 1.8T - Polo 9n3 - Volkswagen - Shop By Car | Awesome GTI

Oil temp/pressure adaptor:

42 Draft Designs VW Oil Pressure Relocation Kit - Polo 9n3 - Volkswagen - Shop By Car | Awesome GTI

I assume it goes into that port for a sender. Thats vacant on our car isn't it? - i'll have to have a squiz today

The little plug on top of the filter mount could be used. Pretty sure that's where my Oil pressure gauge runs from.

I honestly think you've spent excess time on this Sam.

Fit an oil cooler and delete the heat exchanger. Don't go mad with the size of the oil radiator.

True, but I'm glad I managed to suss a few things out before I got it all back together.

It would be good to get those sensors installed

Sounds like a plan

I've got a correction to make. A few posts ago I mentioned how VW had told me that the standard replacement thermostat is a 83/102 unit. Well today I was down there picking up a new radiator and PCV and asked them to check again on the spec and it is in fact an 87/102 degree. There was no optional 83 degree one in the system or any other possibility so what they told me previously was definitely a mistake and what VW sell does line up exactly with the aftermarket ones recommended for our car by dayco/tridon that are 190 farenheit opening.
