Thread: D2 radiator fan on - is this a symptom of doom?

Nah the temp gauge is useless. Get a ScangaugeII or other meter to get an accurate reading.

I know you said that you are broke but if you cane scrape up $150 get one of these.

ENGINE WATCHDOG TM2, Engine Overheating Alarm, Gauge & Sensor

They measure the temp of the steel, not the coolant, and if temp starts to climb an alarm will sound long before any engine damage.

Yeah I've seen the TM2 talked about. Does the nanocom cover that functionality at all from internal sensors? $150 is a good slice off a nanocom.

I'm hoping against hope that this is just a faulty temp sensor, nut the low fluid level scares me.

Try the relay box near the overflow tank. My V8 2000 fan was staying on after switch off i took the relay out and swap with another one problem fixed. has done it a couple of time since so i sprayed some contact cleaner on it hasn't been a problem since. good luck

I would think the only difference between Nanocom and the temp gauge is the Nanocom will give you the actual coolant temp, but it would have to use the same sensor as your temp gauge to get the imformation.

I agree that the $150 is close to half a Nanocom but if it saves you from cooking your TD5, need I say more.

I ordered one of these last week for $15. I have not received it yet, but it supposedly you just connect it to your OBDII port and connect it via bluetooth to your Android phone and use an app called Torque to read temperature as well as loads of other stuff.

I think this was discussed recently, in that they will supply basic factors, but they're more designed for newer cars.
Paging Don Offtrack, I'm sure he'd know.

I think Wil has a td5 so a generic reader wont be much use. Diesels weren't required to support OBDII until 2005, so the coverage of PIDs is very limited. Its a few years since I had a play and I couldn't say with any certainty that coolant temp is one of the available PIDs. I know that what was available wasn't that interesting - rpm, road speed, calculated load, throttle position were about it. I'd gone to the trouble of buying a kiwi wifi and it was essentially a complete waste of money for real time monitoring.
