300 tdi getting hot

Hi all. Just a small problem (i hope) this time. Bertie is running lovely and did over 1500 miles last month but i have noticed the temp nearly in the red on long uphill sections. so..... I flushed the system and because i had a new spare water pump i fitted one and a new thermostat. Result, not a bit of difference. I fully flushed the rad 6 months ago when i did the cambelt ( how easy is that on a 300! only took me about 2 hrs and i'm a self confessed numpty ) so am I looking at the head gasket next? she uses no water and doesn't budge of the middle of the gauge unless she is towing uphill. (I'm running 35" BFG's and a standard defender box.
Cheers all once again.

what condition are the rad fins in ? have they corroded away or maybe even blocked with mud and dead animals ?

I'm with Sean on this. Have you been offroading your landy. Many a landy owner has fallen foul of mud setting like concrete on the outside of the rad.

the other thing to do is take orf the cowling and have a look at the condition of the back of the rad.although you flushed the rad the rear could still be full of mud n ****e

just another thought what colour is yr landy?
























cos everyone knows red ones dont go uphills

Do you have loads of ****e hanging off the front of it blocking the airflow to the rad? steering guard? etc. I would imagine towing uphill running 35s is putting alot of stress on the engine. If your restricting the airflow to then that could be the cause.

i run 35s ,steering guard,winch, abar,4 wipacs on the front,and i tow a large box trailer full of disco equipment and the 200 tdi sits bang in the middle of the temp guage uphill or downhill,
