I'm sure this is covered somewhere but don't have the energy to look LOL...

Took wifeys truck out to get an Xmas tree tonight and it struggled to warm up on a 20-mile round trip....needle stuck around the 10-11 o'clock position and I was bloody frozen......and when I stopped in -3C the have a squint under the bonnet the dear old vicious fan was running like a demon....

Depressed of Llandovery

Ahhh, just found the other thread. Vicious fan definitely working full time so will need to do some more digging. Still, at least its not my car LOL!

blocked heater matrix?? happened to me a few weeks back except mine went to over heat (no heat out of heater though) I changed the thermostat after a good defrosting, added neat coolant and its been mint if not better than ever since.

well the trucks only 7-8 years old and if it had a blocked matrix I'd expect overheating.

Stopped after a 100-mile thrash from Llandovery to Leigh Delamere and took the rad cap off with my bare hands and not a sign of any steam!

Gauge gets to about 11 o'clock position when doing 90, but at sub-50 its barely off the lower stop and the heater is lukewarm.....going to try blanking the rad at Colins suggestion but thats so bloody 1960s, I can't believe there isn't something wrong....but no idea what?? Viscous fan seems to be running full time as far as I can see, which I wouldn't expect if the rad was only warm as opposed to hot....
