Engine Overheating Problems

Hello Rovers,

I am having serious engine overheating problems. (newer Radiator, new hoses, new fan belts, new thermostat) Yet the engine red-lines from simple driving. If I start driving and keep going I am okay. Once I stop for traffice etc..the temperture guage climbs and never recovers...Any suggestions would be greatly appreciated.

Thanks,

Michael

I fixed my by changing the thermostat and topping up the water - some people need to get there's filled under vacuum. The new thermostat may be faulty ... I bought one which is designed to fail open ... risking over cooling rather than over heating.

Also does your fan pass the rolled up newspaper test?

Overheating

I will try a new thermostat. Someone also told me that once the engine overheats the thermostat may go bad again, which has happend multiple times.

I am wondering fan clutch??

I tried the stick from a lolli-pop which I assume is the same thing as a rolled up newspaper..??

Not sure a lolli-pop stick is equivalent to the official land rover rolled up news paper ... wouldn't hurt to try.

I checked the level and added water at 3 points - expansion bottle, rad top and the level tube on the top side of the engine ...

You can eliminate the thermostat by running without it ... the engine wouldn't be able to heat up into the red ... that would confirm the thermostat was the issue.

the most expensive one in autozone ... about $13

not much use though if your truck isn't running! Did you get the pictures I sent for the ignition switch?

But one of my clutchless fan setups. I am curious how well it will help your situation. Get the air out of the engine with a good thermostat first though. Have you had the radiator removed and rodded out or cleaned? That is importnant as well.

Fix the problem - THEN buy one of the clutchless fan setups ... otherwise you are just masking the issue ... These engines can run and stay cool ... even in 90F ambient sat for 2 hours while surrounded by cars on the George Washington bridge ... ask my how I know!

Thank you for all the replies..

First I am going with flushing the radiator..then thermostat..always open..then maybe a fan clutch.

Take Care,
