Hi All,

On a few (rare) occasions I have had problems starting my 3.9L Series I Discovery when it's hot. The starter does not turn (but the rest of the electrics are OK). If I let the engine cool down for 5-10 mins it's fine. I've never had this problem starting the car from cold. Excuse my ignorance, but could anyone explain whether their is something under the bonnet which prevents the engine being started if it's too hot?

I live in Malaysia, where it's pretty toasty, so it can take some time for the engine to cool down after running.

I was considering getting an additional electric fan fitted which I could have running for a short while after the engine has stopped. I'd really appreciate any thoughts on this.

Best wishes,

Andy
 
Could be as simple as a clogged air filter or the starter solenoid being defective ie. loose contacts/wiring expanding with the heat and therefore bracking contact.
Gould also be the water temp sensor giving problems, but unlikly as u say the starter dosen't work.


The 3.9 also gets hot in the UK summers when parked up after a run. U can fit an electric fan such as a Kenlow to replace your existing fan and wired to a permanent 12v supply and not via the supply thats on with the ignition circuits.

Whe the engine refuses to start, take a reading of the voltage at the battery. Then take a reading of the voltage at the starter. Then take a reading of the voltage at the starter while someone is trying to start the car.
