Hi all
As the title suggests, is a diesel radiator different to that of the petrol? Mine split across the top plastic part, we've bodged it with a soldering iron and araldite but don't want to risk it for long and there's plenty of cheap petrol ones but not the diesel. Cheers in advance people
 
Nope, the diesels are all the same. The quality can vary a bit though, and check that your new one's got a baffle before you fit it.
 
With both the input and output at the top there has to be a baffle in the middle to force the hot water down into the rad. You can check it by putting a marble or small pebble into one side and seeing if it rolls out the other - with the rad upside down of course.
 
I'm not too sure about this but I think that the diesel radiator with a manual gearbox is different to a radiator with an auto gearbox.

Ah I see, is this something that can be added or should just be there?

It's got to be built into the rad, and be done well as there have been reports of baffles failing in some rads. Without the baffle the rad is essentially useless as the hot water simply goes in one side and straight out the other.
 
Diesel manual radiator has an oil cooler built into it, automatic does not. Two different rads.

Don't know who wrote what you read, but whoever it was didn't tell Land rover. They seem convinced they only fitted radiators with oil coolers to manuals and radiators without oil coolers to autos. PCC108470 Auto and PCC108460 Manual. But what do they know? :):);)

Some after market stuff claims to cover both. Island only stock one rad for the diesel it has auto and manual parts numbers as it's scope. I would try and get a pukka auto rad. Genuine are bloody daft money though.
 
i fitted an island 4x4 radiator yesterday. it has inlet & outlet for oil cooler pipes but on my auto DHSE its not required. i just left them blanked. not sure whether its baffled??
car seems to run nice and cool though - just been out for a test run

Rad HAS to be baffled. If not no cooling takes place, as hot coolant just flows across top of rad. Baffle causes coolant (looking from front into engine bay) to enter at top right hand of rad be sent down right side of rad and up left side to exit again at top left of rad. Without baffle this flow cannot take place. :)
 
i thought there seemed to be some suggestion that some aftermarket rads didn't have this baffle - hence the marble test. i was just wondering if anyone knew whether the rad available from Island (made by nissens) had such a baffle?
