Take a temp gun to your radiator when you are up to temp. Had the same issue and After throwing parts at it, I got a cheap temp gun and My lower section had little to no flow to 30%+. Re cored radiator and all set.

My 90 is doing something similar, only I'm not on a trail but in stop and go traffic on the way to the mall. No red zone on mine, just warmer than normal, but I am going to start with radiator recore and fan clutch. I was told the water pump would weep if it was going out. Radiator would be first if it's original.

When my WP went out it was sitting in traffic with warning signs as the temp rose. Then as it started to seize shrieks from under the hood.

Next time your engines good and hot, shut it down, open the hood and try to spin the fan by hand. It should not spin freely, should be resistance. Just had the same problem with mine and when overheating you could spin the fan freely. New fan clutch solved the problem and I was shocked at how much louder the engine was with the new clutch installed. My fan roars now.

You can buy a HD clutch fan from O'Reillys for $66 plus tax. Part number 2991. Other auto parts stores carry it for the same price. The box may be Haydens, ImportSelect, etc but it's the same part. I just ordered one for my 99 DI to go through the cooling system. I'll be replacing the original rad too with a cheap aftermarket unit (either a rockauto or ebay plastic/alum unit in the $260 to $340 range). I had overheating issues this past week on the beach, in slow traffic and on the highway running a/c. Besides the old parts I believe a lot of my problem is associated with the DS converter clogging up (it rattles like crazy). The new aftermarket Y-pipe is in the shed waiting to get the truck up on the lift.

definitely do the fan clutch first. In my experience, a clogged radiator wouldn't cool an engine even if you were traveling at highway speeds. It would be instant overheat.

The viscous coupling was replaced about three years ago and the fan was moving fine at idle but I will double check it.

HD clutches are pointless. They run constantly, create a load of notice and suck gas. You'll be far better with a standard one.

test it with a rolled up news paper. Once hot/warm you shouldnt be able to stop it

I'm hearing you. When I use a standard replacement my LR is as quiet as a Lexus. I also noticed a .14 percent drop in fuel economy with the severe duty unit.

Lots of strange advice in this thread. It is very uncommon for a Land Rover water pump to fail in a way in such that the impeller is not pumping enough fluid. Fan clutch and radiator would be the two most likely causes, and to be honest the radiator is probably due for a replacement if its original anyway. I don't see any need to get a Genuine water pump. The last Genuine V belt water pump I got came in a Land Rover box that had a Genuine water pump gasket and then in a bag there was the water pump and a cheap paper gasket. That indicates to me that it is just some re-boxed cheap aftermarket part.

I'm with Uncle D on this one…fan clutch! Replace your thermostat too…unless you remember when you replaced it last.

Finally got around to dealing with this. No problems since that trail... Checked my coupling as per uncle D's instructions. It was stopped by the newspaper.... While changing the coupling checked the pump. Had a slight play in the shaft and a small rasp in the bearing. So I changed it out as well....
