Temp Guage

[stars-r-us-1]

Hi Can anyone advise

I have had a new head fitted 2.4 new water pump new fill up cap and the system flushed out and yet the temp still keeps going close to the red.
I can drive for around 10 mins at normal speed and as soon as i put it under a bit of pressure up she goes, i have got all the air out, i have even tried it without the stat but still the same. as soon as i drive at around 40mph it goes back to normal. the fan kicks in as soon as it starts to rise.
I have checked both rad pipes but hot.
This one has got me stumped
The heater at the front works but i dont seem to be able to get the back one hot, warm somtimes.
I have put the hose pipe through the hole system at high pressure to see if any blockage but no high pressure comes out the other end.
I am not losing any water anywhere it justs keeps getting hot.

I can drive around all day at around 40mph and its fine but as soon as i come to a hill up she goes, it seem like as soon as it needs to work up she goes.

Any advise would be helpful

Thanks to all

Steve

I think that you need to check the viscous fan to see if it's operating correctly, loads of threads on here about it.
