Do you think I need a new radiator? Picture inside

N54Society · 12-17-2015, 11:36 PM

I don't know where this could have come from other than the inlet for the radiator. Just a little coolant drop sitting on the radiator inlet. I wiped it off but I as I looked closer, there is a trail of dried coolant on the side of the radiator. Not a lot, just a tiny bit. I have 115k miles. Time for a new radiator? Something I just remembered, I topped off the reservoir a few days ago because the float was low. Air in the system maybe?

Thanks

Yes you do need a new radiator. There's a hole and you see the stain from the leak. At your mileage it's not unusual for the plastic to fail.

I have a mishimoto all aluminum radiator I can sell you.

I had a very similar pinhole crack on my car not too long ago, to answer your concern yes you need a new rad sooner than later

While you are there, make sure to replace that long skinny hose that goes across the front. It brakes when you least expect it and will probobly break when you dig into replacing your radiator.

JBWELD that shit! i did. lol

Mishimoto or CSF both really good options

Looks like it needs replacement sooner then later.

Mishimoto will fit since you have MT. Or you can go with CSF as they have an Auto and manual radiator option for the 335i.

Honestly I had a hole and crack in my radiator. I went to Pepboys and bought a radiator repair leak kit and all was good

. It was pretty much a putty you rub together and stick it over the home lol

Your upper hose is about to go as well. Looks to be a shade of brown in the pic, which means the plastic is old and brittle. To minimize BMW's notorious cooling system nightmares, replace the upper hose, expansion tank, and the vent hose that runs along your radiator. Don't forget to get a new insert w drain plug and orings for your hose adapters

Turbo_power4ever · 12-18-2015, 07:28 PM

Just throw an egg in there lol

limitdown · 12-18-2015, 10:21 PM

I've had a CSF for 10k miles. Fitment was perfect. Keeps temps very stable.
I bought it from redline360. Make sure you get the correct one. 6AT and 6MT are different.

While you're in there, change whatever other hoses look old

It's slightly used. I'm running a CSF Radiator now so I don't need it.

Check PM.

I find the CSF Radiator serves me better on the track.
