Outer Limits 4x4 Board

Hi everyone.
I have a 82 Patrol Wgn 3.3D,i have noticed that in the last month or so that the temperature rises rapidly to over 3 quarters if i have to accelerate quickly or travel up hill even if the engine is cold, but then drop again when i stop the car or idle, but i an not losing any water..
Thanks for your help...

sounds like a water flow problem so have your radiator flushed and consider a new one also change the thermostat . It worked for me.

yer sounds like you have a blocked radiator to me. if you have done a pressure check and there no obvious sign of loss of water or blown head gasket then id go for the radiator.

Thanks for the quick replies guys.
Can i flush the radiator properly myself? or should i take it to a radiator place.
Apart from water loss, what other signs would there be if the head was blown, and if it has,how much water would you lose.
Thankyou

if the radiator tunrs out to be blocked partially. it is best to remove it and take it down to your specialist unless you have the facillities to remove the tanka nd clean it your self. if you can remove the tank use an olf ford dipstip. fits perfectly down the tube. done it many times.

as for the head, first check your oil, check and see if there is any signs of water in the oil. if there is then do a few more tests. it would use a litlle or alot, depending on the extend of the gasket damage or the head damage.


cheers

When i did my head gasket it didn't lose much water at all untill worked hard, uphill, aircon on, or just a real hot day. Then it would cook and cook bad.
No oil apparent in the radiator water, no water apparent in the oil either. even a CO2 (i think that's what they test for) test on the radiator came up fine. Some air bubbles in the radiator water and excessive condensation from exhaust were the real giveaway signs.
Attempted a compression test, but being a TB42e removing plugs is an absolute biatch, the 3 i did remove showed acceptable compression. If i'd been able to get to no.6 it would have been way down for sure.
Once the head was removed the blown gasket at no.6 cylinder was easily evident.
Before all this i had eliminated every other possibility by re-coring radiator, replacing thermostat, hoses, water pump, clutch fan hub, and even tried running thermos.
Replaced items were knackered anyway, radiator was shagged, and thermos were a complete waste of time. When i had the head off i replaced EVERY hose on the engine, especially those pesky heater hoses tucked b/w the firewall and engine that always split and are a mother to replace when everything's red hot and you're in the middle of a hardcore 4wheel track in the rain up to your elbows in mud. (sorry, i just had a recuring nightmare of a blown hose midway through Vic Range track one winter )

Did it show any signs of being down on power

Normal road use wasn't really apparent cos it'd been stuffed for so long i'd forgotten how it should drive. Wasn't 'till i fixed it that i noticed the huge power gain. But off road under load it struggled and bogged out big time. The temperature gauge would sky rocket at the same rate as the engine dying. I'd have to use low range 1st and 2nd on hills that'd normally be driven in high range, or even 2wd, just to ease the load on the engine.

Best way to describe it was like towing an imaginary caravan all over the bush. Drove the Sisters at dissa like this too. Had to wait about 30mins at the top of each hill for the car to cool down a bit before tackling the next one. (At least i now know i can take a caravan up there if i ever desired to )
