Hay all
just replaced my radiator today took 1.5 hours my old one had been neglected by the previous owner and the cap wouldn't seal because the plastic had corroded away mechanics were asking 380 to 400 for the job so i had a look at the job and had a crack picked up a second had radiator for 125 with 50k on it
real easy change out dropped out the grill and undid the retaining bracket hoses and transmission cooler lines and out it came fans and all
if you need to do this job do it yourself very easy just alot of those painfull black plastic expansion trim screws i had to take half a dozen of these each side underneath to allow acess to the base of the radiator but you dont need to compleatly remove the plastic plates just enough to flex them out of the way to get to the transmission line and 2 bolts holding the ac radiator

Hi Andrew,
well done- where did you get the secondhand Radiator from?

disregard.....wrong car

I too have needed to change my radiator, however I went for a new unit, the part number is MN180514 the price was $314.93.

If your radiator needed replacing you had better check the thermostat i reckon.

I had to replace my thermostat 5,000 km prior to the radiator. I was surprised as its only ever had genuine Mits coolant/fluids and servicing, another family member also has a 380 purchased at the same time serviced the same, now with 10,000 more km, however it still has its original thermostat and radiator.

The thermostat on my old 380 conked out at around 125,000 km, despite meticulous maintenance and servicing of the cooling system.
Luckily a new one is fairly cheap and it is easy to replace.

Do they fail open or closed - ie cause overheating or cold running?
