--- Quote from: "denviks" ---i have exactly the same propblem...... no idea what it is. im pulling the caravan to scotland next week but it will be fine as im only doing 60 mph. anything above that and she gets hot. the rad is spottless on the outside and i have flushed it forwards and in reverese. to be honest it was very clean inside too. im gonna fit my kenlowe when i get back off my holiday to see if that makes a difference  :D

You probably will find it worse with a Kenlowe ,I too have suffered all the same symptons ,even with new rad especialy when caning the olg gel and with a Large t/a caravan on,kenlowe  recomend only use a sucker fan if towing less than 1500kgs, if above this they recomend a blower fan and youre existing viscous unit

I cured the same problem with a new rad too!  In fact, it took two rads as the first new replacement didn't cut the mustard..

Well, it appears that the inner surface of the rad (between rad and air con rad) is quite dirty (a bit of mud + general crap), so I will give that a good clean.

But also, a mechanic was looking around and squeezing the pipes (is that a bit like kicking tyres? :wink: ) and the top hose hissed out of the end when he squeezed it :shock:  :roll:

Some of you may remember that I had a clutch replaced a while ago and they took the "engine out" approach. It looks like they also took the "can't be arsed to tighten that up" approach too :evil:

Oh yes, and the two pipes at the back of the engine look well dodgy (why didn't they replace them when refitting the engine?!) so I'll be changing those. The "P" (?) gasket looks like it might be leaking and still a paper one so that will be changed ... plus I might just put a new rad in, just for the hell of it ... unless, someone wants to buy a Discovery that "needs a bit of work"!!!!

gords:
Cleaned the read fins out and changed the dodgy pipes - but it still overheats :evil:

Well, I suppose it's a new radiator next :roll:

I have similar problems too. I towed a 2 tone trailer at xmas and the disco was fine. Wonderful to tow with. Then in May I towed my 1100kg caravan and it was fine but a little slow up hills but hey it is a 300tdi auto and still got the exhaust re immisions thing on.

Towed a caravan for amate recently and then I bought a t/a van too and the temp guage flew up to red as soon as the gearbox kicked down to 3rd. Keepthe heaters on full blast and it slowed the speed down of the temp rising.

I have numerous problems and tried to clean the fins but with a hose pipe ban that is tricky. also tried to flush rad through and got out loads of muddy coloured water. I have a slow water loss too.

Edited to remove all my bad spelling
