Radiator help

[Si316]

hey guys and girls

Just wondering can i fit a 325 radiator with expansion tank to a car that didnt have an expansion tank (316)? I think u can but someone has put abit of doubt in my mind over the pumps being different for the preasurised system.

Ive got a later type 325 radiator and expansion tank to go onto my 316 project car. Its time to fit it to the car and i cant see how its going to fit. the old 316 one pushed into 2 brackets on the car at the bottom with a nut and bolt at the top. Does the 325 one fit the same or different, i think im missing some of the brackets on the 325 radiator. Can anyone show me a pic of how it all sits in the car?

Cheers
Si

i had a m20 rad recently and it def needs two supports at the top

If you look at Karan's engine bay; you see what i mean? on this thread half way down...

Very very close now mate!

ahhh yeah i getcha, what is there at the bottom of the rad mate do u know?

Need all the brackets for the expansion tank too. might just fit a new 316 one if i need a million and 1 brackets lol.

did the 316 have the expansion tank on the actual radiator?

if so would one out of an e34 525i not fit?cos its a similar arrangement?

[Si316]

no mate the 316 didnt have an expansion tank at all. it fills up through the top of the radiator.

forgot about the ones with the expansion tank on the side hmmmmm

Why do it dude? The rad you have should be good enough?

Was just looking to upgrade it really while im doing everything else. needed a new rad as the old one was leaking anyway.

The top is ineffect the expansion tank.

Wayne30 has a nearly new m10 rad.

M50's have expansion tanks at the side! HUDGE radiators though! never neeed a fan lol

Are you tryung to rig the expansion tank on the intake (late 325i-good cooler area of engine) or exhaust (early 325i-not so good hotter area of engine bay) ?

cool-i'll log that ! *m10 no expansion tank*

another option could be a rad out of a facelift 316/318i
