Safe coolant temperature of a Td5

[se7enup]

In a thread elsewhere (http://www.aulro.com/afvb/technical-chatter/59669-td5-dont-trust-temp-gauge.html)on this forum, a coolant temperature of 107 degrees was mentioned.

(They also mentioned people plugging in Nanocoms and scaring themselves:angel:)

Can anyone let me know the operating temperature range of a Td5 engine is and also the maximum safe coolant temperature.

Thanks in advance

Mine seems to run around 85-90 degrees coolant temp (Nanocom) reading.

nominal operating range is between about 88 and 107 degrees (needle shouldnt move from its center position for that range) 120 is about the limit before irreversible damage is done to the head/gasket.

Brilliant, thanks for the replies.

I plugged in a Nanocom and saw 106 degrees while driving at around 110 kph.
Scared the hell out of me!

Later on in the day while driving an extended distance off-road I averaged 93 degrees with the electric fan coming on and off.
(I guess this is normal due to the lack of airflow over the rad while driving slowly)

While driving home (at around 90-100 kph) I only saw 96 degrees max.


Hopefully this all sounds pretty normal.

sounds ok to me...

when its at or over 107 its time to be going, hrmm perhaps I am working this to hard

over 110 and you should be looking into what you're doing and can you do anything about it. think "I'm towing a 3 t trailer with a full load on board Im in top cog going up a hill and the engine is just hanging on to the bottom of the useable torque curve. I wonder IF I slow down, change down and let the engine rev a bit more might that help resolve the upcoming over heating issue?"

115 is time to be getting worried.


It pays to periodically "IR read" the temp sender and compare it to your nanocom, if nanocom reads lower than the IR thermometer (assuming the IR thermometer is correctly calibrated) then you need to do some investigating.
