New radiator needed

[disco gazza]

Mate took his son's TD5(2004)down to see his doctor. He noticed it was leaking when he got there.
Its got a nice split down near the bottom.
Is there a particular brand that does it better than others or it doesnt really matter.
Also where would be the best place to purchase said radiator.
He lives in Sydney
TIA
cheers DG

You can get alloy ones, such as PWR, Allisport etc, but I think most just get an genuine/OEM replacement. The Td5's have heaps of capacity in the cooling system.

In Europe the best aftermarket for Td5 is considered Nissens 64312A, i bought one myself about 5 years ago and i'm pleased with it

That's the one to buy considering how long the original ones last.

I replaced mine with a Glasgow Radiator 11029, which was I think also an OEM. Not available and the Nissen is. Note not a Nissan!

Why the heck is so expensive there cos it's correct price is this 64312A - Radiator, engine cooling | Spareto (https://spareto.co.uk/products/nissens-radiator-engine-cooling/64312a) ?

[AK83]

shipping is not cheap.

Mario wouldn't sell sub-par parts, he sourced a Nissen for Epic Dragon's car.
Any feedback ED?

I got an Allisport in mine Cost me about $1600 from memory.

A lot of money I know, however it gives me piece of mind when I am in the middle of the simpson desert I will not over heat or have a radiator fail.

Eliminates all plastic bits which are a weak point. Also Allisport claim that this radiator is about 30% better cooling efficiancy.

I can tow a very heavy 20 foot caravan on a 40 degree day and the temp gauge never moves past the middle.

Just be aware that the gauge's position is a bad joke made by LR...it goes to the middle at 70*C and stays there untill 119*C then at 120 goes to the red so it's technically possible to drive it at 115*C for long without knowing it and that would "tenderise" the engine on a long run.... better fit an additional gauge to see the real coolant temp all the time.

I had a so called "performance" alluminium rad myself(not Allisport) but after about one year i gave it to a friend who has a competition defender and fitted standard Nissens to mine cos i didnt like how the coolant temp behaved with it... the ECT fluctuated too often between 75 and 100 depending on the throttle and engine load(used to tow a boat from time to time) so IMO it went too cool on light throttle which increased the EGT(i have both ECT and EGT gauges) and went up too high quite fast when the engine was forced.... IMO it had too much thermal inertia and so many ECT fluctuations are not good for the fuelling, with the Nissens once it gets to 90 it stays around that value with small fluctuations and i like that more.

Do you feel that increased cooling capacity changed coolant temps faster than what the thermostat could respond?

Good question... never thought that way, i just described my own experience without thinking why it happened[bigsad]

[Tins]

It is a good question. I would have thought that the larger capacity would have led to more temp stability, once op temp was reached, which would take longer.

Unfortunately(for me) i didnt think at all just went after the advertisement and believed some good reviews without additional research... i discovered what i revealed cos both my ECT and EGT gauges were already fitted .

If the thermostat is wide open (engine hot) the water pump will have the coolant roaring around the system.

The coolant needs to stay in the rad long enough for exposure to the ambient air temp to be cooled, so many stock rads have some sort of baffling in the tanks to slow the flow.

Pretty vsure the stock 300 Tdi has this (for example).
