What fluid do you have in there? Watts ÷ Volts = Amps.

Ethylene-Glycol based coolant, local made compatible with TL 774F 50% dilution. According to the manual should be Texaco XLC (also ethylene glycol) which is also compatible with the TL 774F in 50% dilution Cheers Eduardo MY 2007 110 SW PUMA 2.4: Big Fog of 64' MY 1994 Jayco 1207 Folding camper: "El Tremendo" ![]() Click image to enlarge Last edited by Eduardo on 3rd Dec 2018 10:47pm.

Humm, if the new radiator fails, probably that should be the way... Thanks Eduardo MY 2007 110 SW PUMA 2.4: Big Fog of 64' MY 1994 Jayco 1207 Folding camper: "El Tremendo" ![]() Click image to enlarge |

Stupid question, have you changed the viscous hub?. No offense but you guys have no idea about hot weather, both our Defenders have worked in 50 degree Celsius heat for weeks on end, but the fan MUST work. |

Do you have a cat fitted, that would be the first thing to remove.

Eduardo, my advise, cut some gills in the front guards like the Range Rover, what you want is more airflow through the rad, owners have done it here and it makes a huge difference. https://www.google.com.au/url?sa=i&sou...2908023534 |

Are you using 6th gear or gearing down to 5th? -- 2010 Defender Puma 90 + BAS remap + Alive IC + Slickshift + Ashcroft ATB rear 2015 Range Rover Sport V8 Supercharged ![]() Defender Puma Workshop Manual: https://bit.ly/2zZ1en9 Discovery 4 Workshop Manual: https://bit.ly/2zXrtKO Range Rover/Sport L320/L322/L494 Workshop Manual: https://bit.ly/2zc58JQ |

Do you have (even slight!) loss of coolant? Do you observe the OBD temperature of the cylinder head? |

Eduardo, I had exactly the same problem as you. Hills, high air temp, revs. But the clue was hills (and suggestions from the forum members) that my coolant was low. Is yours at the right level? No blockages or air bubbles? It sounds so similar. I topped mine up and now keep a regular eye on the level, and never had the problem occur again. Also gave the MAF a clean at the same time, but coolant was the key, it was low. Add the hills and it just seemed to accentuate the 'level' whereas flat roads seemed to be ok. It was obviously on the threshold for the ECU to turn on the limo mode. |

I cannot take out the catalizer (MOT restrictions in the city) I have also a temp readed connected to the ODB So I can low the gear when the temp goes up to 105°C but is quite anoying in special in the long trips.
