and what is in the trailer???

Yo Happytgu suggested very early to tap the Cat, could be something simple like that but nissan have pulled Goats 4x4 apart plenty of times,
they can't be that BLIND can they.????? Choked up throttle body, butterfly. ALL THESE THINGS WOULD OR SHOULD HAVE BEEN CHECKED ALREADY< BUT YOU NEVER KNOW
I don't know, but surely it can't be that hard for the experts to fix......
It really depends if they have the apprentice on the job or the tradesman, who has actually seen and solved a few wierd problems over the years.
Although, if the problem is only apparent towing a load, and again towing it up a steep hill, how are the Nissan mechanics going to replicate that......
I know Goat is up in the NSW Tablelands somewhere from his original intro. I wonder if there is someone else with a CRD that can tow the same trailer up the same hill. You would hate it to be something like a dragging wheel bearing on the trailer itself.

The so-called Nissan mechanics did take a trailer with a 3 ton load out and made the Patrol overheat. That was when the "techs" from Nissan Australia told them to take the driving lights off.
The Patrol is towing a bogie trailer with 1 ton of water. The trailer itself weighs 750 kgs. Should imagine that falls a fair bit short of the 3.2 ton load that Nissan says this model is capable of towing.
And we are between Bathurst and Mudgee. The road is NOT flat (never has been), but we are travelling on sealed roads.
Going to have a closer look at the catalytic converter tomorrow morning. Would have thought that if there was a problem there, it would have been evident all the time, not just when towing a load uphill.
Give it a shot Goat, I really hope it is only a gummed up cat, then you can drive your now non over heating patrol straight through the showroom LOL Nah not really
I've just read thru the thread , sorry to see that you have been put thru the ringer with this . I think that nissan would have checked all the usuall suspects and would have their best mechs on the job as It is obviously bad for publicity if a car keeps being returned for the same problem . The problem may a rare one but not neccesairily difficult to fix . For my 2 cents worth , I think I would check out the air filter , I have seen new air filters that have been fitted still with the plastic wrapper still on them and air intakes that are partially blocked by plastic bags and food wrappers even inside inner guards also air filters that have been clogged up well before their service date .
Goat, If the muffler or cat has only a partial blockage, it may well be the cause.

Thanks, everyone! The mechanic son-in-law came out with me over the weekend and we managed (with little trouble) to get the Patrol to overheat again. The intercooler and turbo were sizzling. It is only when the Patrol has to work at low speeds, ie going up a hill towing a load. We tapped the cat, but nothing appeared to move/dislodge. The intercooler is as clean as a whistle, as is the radiator (no blockages). Don't quite know what I'm going to do from here on in. Don't want to invalidate the warranty (and we know that Nissan will invalidate it in a heartbeat), but need to get the problem resolved ASAP. Fair Trading have issued a file number, and we will be forwarding a detailed "diary" of the problem, as well as what we want to happen to resolve the issue. I shall keep you posted.
All this BS is doing my head in and its not even my car, can't imagine how your feeling. Still this engine cooking can't be good.Quote:
