Thread: Radiators, intercoolers and exhaust wrapping

Exhaust wrap (110 2001 TD5)

Radiator
The last two trips I've hardly got any mud even close to the radiator and I hose it out regularly so I was surprised that I went into limp mode twice on the way back from Barrington Tops recently, despite the extra weight of the Hannibal RTT, awning and rack. 100kph, very slight incline on the F3!

Do I need to take it out to clean it properly? Is removing it a simple job?

Intercooler
I've ordered my new performance intercooler from Allisport (UK) and some silicone hoses too, which should be a good weekend install project when it arrives.

Will this change in any way, the overheating issue that I'm having or will it simply increase performance because it's so much bigger?

Exhaust wrap
I have some exhaust wrap at home and was thinking of putting it on the Defender.
Will it affect engine temperature as a result of the insulation effect and back pressure at all?

Would love to hear your thoughts...as always! As you can see I'm still not that mechanically minded....but I'm getting there, little by little, with some help from you guys!

Something is seriously wrong... A TDCi shouldn't be having cooling problems yet... They arent old enough.

How many k's and how old is yours?

If under warranty - dealer, if not, full rad flush, check pump, thermostat etc..

Sounds very much like a sticking thermostat.

Hey Bobby,

I agree with Tombie, it should not be over heating, even with with the extra's you have on it. I have mine loaded up and never had a problem with over heating, even in the Cape with daily temp in the Mid 30's.

The intercooler will not assist in engine cooling. It may even make it worse ! as it is twice as big and will block out more radiator than the stock intercooler.

Exhaust wrap will help with engine temps. It is my understanding that the heat from the exhaust is push down and kept in the pipe rather than building up in the exhaust manifold and turbo. The engine bay will also be cooler.

Exhaust wrap will help with in cabin temps as well.

Cheers
Grant

HI Bobby - mine has the same issue with it running hot. Dealer could not replicate the conditions or the overheating so they say there is no problem. I fitted a bigger intercooler as well, but have not had the opportunity to test if it makes a difference

Do you have a Scangauge - it is interesting to watch how the temp climbs and drops sometimes without any change in speed or grade.

I'm thinking of getting a new thermostat to start off with, just need to find it - anyone changed one before?

I also agree, I had ours towing with all the gear, roof rack loaded in 38c temps in the Kimbeleys with no problems at all. I'd have it checked for sure. The only time my Puma went into limp mode was a fuel pressure fault and this was a known problem and fixed under warrenty.

Good stuff, thanks guys.

I've done 105,000kms (2008 110 Wagon) and did fill up the cooler and radiator with mud on one trip - that was the first time it happened, coming back from there. I gave it a good rinse out with the hose but suspect I'm struggling to get all the mud out.

Any climbing seems to do it. I have no scanguage but I'm due for a remap soon....early 2013 I think!

I feel the lack of throttle and immediately check the needle and watch it lift up above halfway and shoot rapidly north.....then I pull over and it goes down to halfway and I'm back on throttle. Gets worrying when there's no hard shoulder...

If it's a thermostat issue, is fitting a new one a simple change?

I had the same symptoms on my old D1, anytime on the soft stuff up would go the temp. The guy who built the new radiator for it said they don't need much in them to push them over.

................. The last two trips I've hardly got any mud even close to the radiator and I hose it out regularly .........................

Have you been careful not to bend the radiator fins over when hosing out ? This can be a cause of reduced airflow and overheating.
