Thermostat Too Cold?

thats a how long is a piece of string question....

its more a combination of age, over heating, and any other number of variables.


Id hazard that so long as you havent cooked it properly you'll be ok.

OK - sounds like I will stick with the standard 180/88. I am not too worried about the 14CUX because it usually runs on LPG. I will drill a few holes in it for the extra flow though.

You are determined aren't you.
On any coolish day the car will run too cold if you put holes in the thermostat.
I had a problem with mine one day when I went to the Blue Mountains and it was 5C or so. The car dropped down to about 50C and the enrichment came fully on.
I pulled out the thermostat and found that the valve was not seating by the barest crack.
In your case with gas you may find that the gas exchanger heating may not overcome the latent heat of evaporation of the gas, and it will freeze.

Leave it alone. If it is overheating it is not caused by the thermostat, as long as you have the correct size thermostat in it. The place to start looking is the radiator if my assumption that the car is heating up is correct, as you have not explicitly stated it AFAIR.

In the 1.8 it was to reduce thermal shock by keeping the water flowing, the v8 doesnt have this issue. I was just saying that it had no adverse effects over 20,000kms running cooler/with the holes.

The P38A has its thermostat in the bottom radiator hose. I wonder if that's also part of the problem they have with overheating and slipping liners

OK - I will leave the standard in it for the moment.

It hasn't overheated yet (for a couple of years anyway).

I just had a day when I drove it 150+k's without stopping when I would normally only drive it 65 k's. This day it got up to between 90 and 95*, but it was almost 30* ambient temp.

I will leave it as is at the moment and just keep watching that gauge:p

Thanks

The official fix from Land Rover for the 1.8L thermal shock issue was a remote thermistat in the top radiator hose. Remove the one on the lower hose entirely. I'm just too cheap, holes are cheaper than $300+ for the kit and reduce thermal shock similarly. It just takes much longer to warm up in cold weather compared to the proper fix.
Apparently the thermal shock contributes to the head gasket failures and the subsequent overheating and slipped liners. After the latest head gasket (and drilled thermo) is the only time ever the engine has used zero coolant in over 20,000kms.

Cheers!
