Coolant Temp

[Stoneblade]

A quick question,

 

I think I may have a sensor issue, but need to know if its working properly. I have been having starting issues in the cold weather, the ambient temperature is 6c outside at the moment and my coolant temp is showing at 16c which I used about 4 hours ago. I know water and ambient air temp are different but is this right?

Hi there can we have some vehicle/engine details and where are you getting the coolant temp from? when the coolant temp guage starts at 50 deg c

Hi,

 

Sorry thought it was in my sig. Its a 2002 TDi 1.9 115bhp. I had this feeling it was too high for the water to be sat at cold, was expecting similar to ambient temp.

 

 

I am using Vag com to get the temp from the sensor, and checking starting conditions, as the glow plugs are set at 0 cycle.

 

I have just disconnected the sensor and now the glow plugs are on a 6 second cycle, so I am guessing something is wrong with the sensor. Just dont want to replace if the readings are correct.

 

Cheers

Stick something in the water reservoir......a thermometer would be the best choice.....but a finger would give an approximate ( its hotter/colder than the air ) reading.

lol damn cant find a thermometer when I need one, when the missus gets home from work I will ask her, she keeps bloody everything in her hand bag.....

 

Cheers big_kev will see what the difference is, hopefully its not too different, but would explain the cold start issues,

Done and tested, all seems good, lol damn that rules out that hitting the starting problem. Now onto fuel lines.
