When you are starting off with 55C outside air temperature its easier said than done i'm afraid Bruce...

Certainly that prevent to reach this temps os the best thing to do!
But with this sh&@$" of eletronic engine, that gives you power always, and don't males noise, sometimes you get distracted and forget to reduce one gear..... This things doesn't occur with my brasilian made 2001 Tdi..... It's "evolution" baby!!!! Regards! |

Indeed, LR South Africa was even testing a bigger intercooler here a while ago, not too sure what they concluded. Probably that it's not worth it (for them). -- 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 |

I quickly spoke to Wimpie Willers who did the testing for them and he also said that it made a difference in the intake temps which inturn cooled the engine better and gave better power delivery in warm weather. They apparently gave all the results to JLR but they decided (very convenietly) that the test results was "inconclusive" ![]() ![]() I gues the okes with thick glases and calculators have the final say..... ![]() |

Check water level, had a client here in France, the car started to mess up like yours about a year ago,loss of power on big hills form time to time. Then it bakame worse until it wouldn't go for 15min before loosing power.
Afther a CO2 test, it was a head gasket gone on cylinder N°1. Water level was goind down, and evrytime an air buble went past the water sensor, the heat would go up, the gage went very rapidly in the red for a second and went down with engine loosing all power. Alex. |

Will see the water level....but it isn´t getting low....but I´ll check!!!
Thanks a lot! |

This has just happened to me. Normal driving conditions and the power was cut from the engine. I believed it was electrical and contacted the dealer as I have only had it for 7 months. I had also had problems with the heating (I guess some of you guys don't use it that often!). The dealer suggested it was electrical as the temp gauge rose quickly, the car enterered "limp mode" and cut power to the throttle, the car began to coast and then the temp gauge would come down and the power to the throttle would be reinstated. To cut a long story short, I am losing water from the header tank and the car was overheating. After topping up the water the problem has gone away and the heating now works! Unfortunately I have not got to the bottom of the cause of the leak (no visible sign). Head gasket? Air conditioning? This does seem like it may become a common fault. |

Hi, I am also losing coolant with no visible leak even when pressure-tested. I was thinking it's just the cap that's loose, but another Puma owner had the following happen to him:
I am so going to get a gas test on the coolant tomorrow just to find out if this is also happening to mine, else a moerse repair bill is coming my way! ![]() 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 |

I've heard that it is good practice to "torque" the head bolts every 20 000km odd. Is this true and does LR ever check the torque on the head bolts? ps....Naks can you find out what was this "R30k" upgrade he did? Last edited by Regard on 8th May 2013 12:30pm. Edited 1 time in total |

If you're losing coolant with no apparent leak, you might want to try changing the cap. If that makes no difference, then check that the water pump isn't leaking. There's a drain hole under the pump to allow any leakage past the shaft seal to drain out, but it then drips onto the PAS pump and it is incredibly difficult to see where it's coming from.
Mine was doing exactly this - I changed the cap because the old one wasn't pressurising the system properly, then started losing MORE coolant. Eventually traced the leak to the pump, replaced that, and it's been OK since. With low coolant the heater becomes even more erratic and uncontrollable than usual! |

Hello everyone!
Any news about this "overheating"? My 90 is everyday worse.... now that is arriving summer in brazil, i´m lost! These days, I was towing something about 2500kg, in a trip, and I finished a hill in 2nd low gear...and cutting power also.... Everythig always right: No losing coolant at all!!! Now with 99750 km. Last time in the dealer changed the temperature sensor, the performance off the engine get better, but the problem was not solved.... Will try the termostatic valve next time.... The thing of change the intercooler, will really works???? I´m losing the hope, because It´s not possible to uso the vehicle for what it´s designed for..... Well, hope some of you have solved your problem and have some opinion to help!!!! I have a lot of videos of this "overheating".... will try to put in the youtube and will post the links here!! best regards for all!! |

Hi Gabriel
Do not feel alone. Down here in South Africa a lot of the owners (esp those who tow extensively) struggle with the same problem. Two things: Obviously never tow in 6th gear. On the Puma the 6th gear should be seen as an overdrive gear and esp when towing should rarely be used. Then the intercooler.......your car will be transformed! I've done multiple tests on standard intercooler only, standard with remap, upgraded intercooler only and up graded intercooler plus remap. The intercooler only is the way to go if you just want to protect your engine. It gives more torque esp at lower revs and it feels like the car never runs out of power. If you want to go really fast as well do a remap on top of that. I've tested both the Allisport as well as our locally made intercooler using an UltraGauge to monitor intake temps, coolant temps, etc, etc... Both intercoolers did equally well and there was no significant difference between them in terms of performance delivered. Our locally made one is a very well researched and developed intercooler and it shows on the readings!! Most of our drivers who does heavy towing has gotten as far as pressurising Land Rover South Africa to install upgraded intercoolers even before the car leaves the showroom floor! They (LRSA) are very well aware of the problem and recognize it as an design fault. They (LRSA) was asked by JLRUK to do formal tests with our locally produced intercooler. The results were significant but JLRUK for some reason ignored the test results they requested???????? (Probably saw a hell of an expensive recall in the making!!!!!) But because JLRUK would not except it they can't fix it as a recall. They (LRSA) will now upgrade the intercooler (at the owners expense) but will "forget" the whole "invalidation of warranty" story due to "modifications". So basically, they know it is the problem but can't care to do much about it. JUST DO IT! GET AN UPGRADED INTERCOOLER! |

If your engine enters limp mode after accelerating in 6th gear, you might want to read this thread about turbo underboost: http://www.defender2.net/forum/topic5125.h...underboost
After many hopeful repairs, mine turned out to be caused by a damaged wiring loom running from the ECU to the turbo modulator. Its easy to inspec the wiring loom and elimintate it as a possibile cause of your problem. It is a common problem with many defenders the same age as yours. Kirk |
