The Badger Posted June 21, 2011 Share Posted June 21, 2011 So, as the title surgests, can a worn clutch cause my engine to overheat? coolant level is fine (could do with being flushed), oil pressure & level is fine. It does feel down on power a little too. Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted June 21, 2011 Share Posted June 21, 2011 A worn clutch would slip and may smell like it's burning. How are you noticing the overheating? Via the gauge? Quote Link to comment Share on other sites More sharing options...
The Badger Posted June 23, 2011 Author Share Posted June 23, 2011 yep, my temp gauge goes to about 105º. If I take it out of gear whilst driving and rev the engine, it can help cool it? I have half changed the gearbox oil, just waiting for the other half of the oil to arrive by post, opps. Gonna see if this helps. Quote Link to comment Share on other sites More sharing options...
Happyoldgit Posted June 23, 2011 Share Posted June 23, 2011 I can't really see how it can be linked but in theory if the clutch is slipping that badly it is causing the engine to race then it conceivably might cause the temp to rise a bit but you'd notice the unmistakable pong of burning clutch lining long before that. Next time the temp gauge rises try turning the heater to hot and put the blower to full whack and see what happens. I'd say start at the basics like the thermostat and then go on from there.

The Badger Posted June 23, 2011 Author Share Posted June 23, 2011 Thanks, just thought I would check, not noticed the burnt clutch smell at all, and my rev are not really going through the roof. I will look try the heater first as I did muck about with adding a bilge blower into the air intake of the heater, it kinda does not work, when the engine is on and we are sitting still I do get more air, but when we are moving then it's pretty rubbish / blows cold air on hot? Will then flush the system, then try the thermostat. Also my power steering box is acting up, this also might not help I guess... Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted June 23, 2011 Share Posted June 23, 2011 Which engine do you have? I know the 300tdi has a special coolant fill procedure to prevent airlocks which will lead to overheating. Quote Link to comment Share on other sites More sharing options...
Les Henson Posted June 24, 2011 Share Posted June 24, 2011 Slipping clutch won't cause excess engine heat. Even if it did - the over-cooled engine would handle it easily and the guage would stay the same. Les. Quote Link to comment Share on other sites More sharing options...
The Badger Posted June 26, 2011 Author Share Posted June 26, 2011 it's a 2.8 TGV, also pretty sure there is no air in it. As I fill it ages ago with coolant and it's been fine for a while, but the weather has shifted from extremely cold to extremely warm. I have recently changed the power steering pump to no avail on making the steering box work. Also on a cold start up, when it is 5º or below the engine does make a little wine until it has warmed for afew min's Quote Link to comment Share on other sites More sharing options...
The Badger Posted June 28, 2011 Author Share Posted June 28, 2011 Actually, come to think of it, the heater was blowing cold air last time I checked, i am wondering if there is a way to test the water pump? Quote Link to comment Share on other sites More sharing options...
Christophers1247 Posted June 28, 2011 Share Posted June 28, 2011 As Les has already said a slipping clutch won't cause an engine to overheat. But if the thermostat turns out to be OK it could be a split air intake causing the engine to run lean(hot), blocked/faulty radiator but when you do a coolant system flush it will eliminate this. faulty water pump, it could even be a faulty temp gauge not likely but i have had it before on 200tdi. does it overheat on idle or when driving?

headhunter Posted June 29, 2011 Share Posted June 29, 2011 I have a 2.8tgv. I believe they tend to run warm/hot, when compared to 200/300tdi's. I fitted a high output radiator from Brunel Engineering and kept the viscous fan in use, as an electric one did not provide the required air flow, in the UK when under load. I first noticed overheating towing (about 800kg) up long hills with the electric fan. Also off road progressing at low speed up hill with the wind behind me. When into the wind the temperature dropped to normal. This discovery led me to consider volume of airflow to the radiator, not usually an issue with 200/300tdi's! Given the above I refitted the viscous fan prior to the planned Morocco following advice from simonr, who intimated that the output from a viscous far exceeds that of an electric fan. With this setup there were no overheating issues in Morocco last year at 38 degrees C, either on long off road climbs or in low ratio deep sand conditions, even fully loaded to max GVW (3.5 tons) and possibly in excess of it...
