Being a newbie to the VX220 scene, I was a bit alarmed when first seeing the coolant temperature reach 106C when in traffic not long after buying it. Then read the manual which said it could go up to 120C so was a bit more relaxed. However, the fans do not appear to kick in until around 105-106C - is this normal? I understand they are controlled through ECU so am thinking of fitting a manual override switch so I can activate them if I get stuck in traffic again (or will try to keep to clear, moorland roads in future!). Are there any guides available as to how to do this? I had a quick look through the forum but nothing jumped out.

scangauge will allow you to do that, also very handy to have

Yep that's normal. There is a guid to manually switching the fans on. Its a case of grounding a wire via switch. I will have a hunt..hold on..

I have something strange going on with my coolant temp if anyone has any suggestions..... My vx normal running temp on the move would sit around 83c (it looks like its a cool running stat) and gradually go up if its on the spot like you would expect. It recently started hovering around 98c as the normal running temp, and with the fan constantly on even at normal driving speeds. I figured it must be the thermostat that had got stuck a bit closed which had been stopping the flow causing the higher temp. After changing the thermostat its exactly the same?! Could it be a faulty temp sensor perhaps over reading, is that possible? Has anyone got any ideas what this could be or what I could try? Thanks!!

N/A? fans on all the time is an indication that the EGR valve is fcuked. Does it drive badly once warm?

The fans on constant can be a problem with the air temp sensor in a Na located in the intake pipe. But that wouldn't effect running temperatures and with the fan on constantly I wouldn't imagine you getting to 98' unless stuck in traffic... Are you losing coolant? MartinS was running high temps and the system wasn't pressurising, a way to test this is once the engine is warn carefully and I mean bloody carefully remove the header tank. If you can hear air escaping through the cap then it's pressurising if you don't then you may have a leak somewhere... MartinS was losing pressure but no coolant from the front bleed valve on the rad hose.

Doesn't running an N/A with Scangauge permanently connected cause other minor running issues?

Not on mine.

Goog to know Cliffe I found the thread below, but remember reading other similar tales from earlier last year (around the National date)... http://www.vx220.org..._1#entry1083896

I agree with all the above, but remember that vx220 110 deg C is not the rest of the worlds 110 deg C..... I have accurate temp labels on most of my hoses right next to the engine block, and in 3 years they never got above 95 deg c. Stack has shown 112deg c many times......

Its a turbo, not losing any coolant and it has plenty in there.

It made quite a lot of air noise when releasing the header tank cap so i can only presume its pressurised?

Its a bit of a strange one really this?!

Anything else i could try?

Thanks!!

Maybe water pump?

[mikeerhymes]

Hmmm yeah maybe thanks! I guess its going to be the process of elimination until something works :-(
