Right now I am in the same situation as you had before. Last month when I went to Lake Tahoe. The outside temp was below 32F. The car took for ever to warm up. No mention the heater can not blow appropriate heat from the vent. The coolant temp shows 69F on my gauge.

The worst case is I swap back to BMW radiator which I really don't want to!

Many thanks

Blue masking tape around the grills, it ain't that hard...

Isn't that looks weird? But thank you!

Yesterday I came for an idea, why not just unplug the electronic supply to the Thermostat? I mean just an idea. I am not professional.

I am sure that would give you a bunch of fault codes.

Cooling tables are adjustable, likely an easier solution for all depending on your needs.

Interesting! Can you show me how and be specific? Thanks

You'd need to contact a flash tuner.

Just ordered my CSF radiator , apparently this should be another mandatory upgrade like the other plastic pieces Bmw loves to put on our stock cars. Aluminum or plastic?! THe choice is clear !! I'll update on how well it works in comparison to the stock radiator next week when it comes in and is installed.

I'm just adding more information to this thread about cooling questions when having a CSF racing radiator in colder environments. My car is a Sept '06 build N54 E90.

Outside temperature: 47 F
Coolant: 90 C
Speed: 70 MPH
Oil: 210 F

After slowing down to 30 MPH
Coolant: 83C
Oil: 205 F

They work great but only as good as the cooling tables within.

This makes sense. The stock cooling tables run hotter while moving, for emissions and gas mileage. With aggressive driving or slow driving the cooling tables allow for lower temps.

The other day when the temperature was ~65 F, the coolant temp peaked at 105 C with 45 mph stop/go but oil temps maintained at 220F. But while driving the temp varied from 97 -100 C.
During the hot summer my oil temperatures never went above 230 F, even with aggressive driving.
I'm also using MHDtuning now but this last summer I was still using Vishnu.

Little bit of a noob , but ::. What are Cooling tables? If I have to get a couple of more items along with the radiator please tell me as i am Trying to do as much preventative and up to date maintenance as I possibly can. I don't like waiting for things to fail. Thx

Hello, for that outside temp. Did you remember for long it take for your 335i to warm up to the operate temp like you provided.

Roughly 25-30 minutes for an outside temperature of around 40 F. It usually takes around 10 minutes before I have any increase in oil temperature above 120 F.
I will check more this week.

The below items inside your tune must be changed in order to target lower temps.
I've had my CSF radiator for 18mths. Temp did drop slightly when i first installed it, but it wasn't anything to write home about.
It wasn't until last week when my tuner Ken/Wedge adjusted my tune's target temps did the CSF really show its true power.

If your water pump and thermostat are a bit long in the tooth, I'd replace those. Also check if any hoses look or feel old. I also proactively replaced a bunch of things while I was doing the CSF. I've been stranded on the side of the road before due to a $50 hose bursting.

You'll need your tuner to make these adjustments

Why do you guys think lowering the coolant temp of the engine under low load/normal driving condition is a good thing?

Well for most upgrading the radiator just helps the vehicle maintain the cooling parameters within. Which is all good but you hardly get your money's worth out of a upgraded radiator when the car is aiming to keep that water warmer then it needs to for emissions purposes.

The cooler water temp also lowers the oil temp.

Both run too hot from the factory IMO. Both were engineered to run super hot for emissions and economy.

If you wanted that upgraded radiator, I see now reason you wouldn't want your temps lowered to something more reasonable.

I aim for 195-205F on the coolant. It's also lowered my average oil temps significantly.

I run a 160T stat in my C6Z

The stock radiator on the BMW when pushed hard, especially with upgrades can barely cope with the demand. Having that extra ceiling with a lower set point helps greatly.

It's definitely not a good thing to me. Unless I track my car. Thanks for your tape method it works better now. I didn't know that the electronic thermostat slightly open as you said even through the car need to be warm up in the morning. I though it open the thermostat latter when I saw the official N54 Coolant data sheet. Thanks

How about if I want to go opposite way since right now outside temp is pretty low and I want my car to warm up quicker. what parts should I change?

Thanks

Mine worked great at the track this weekend. Coolant temperature was always a tick under 205F according to the JB4 dash hijack display. Oil temp never went above 250F either with the Dinan oil cooler. But again, I was forced to run stock boost due to misfiring issues I had, and air temp was only around mid 40 to mid 50 F.

Bumping an old thread -- How has the CSF been in the Chicago area; I'm curious whether the car warms up too slowly when it's cold out?? Any comments that can be offered would be much appreciated.. My rad just stated to leak a very small amount, but it's time to get out in front of that issue...

Stock or CSF seem to be me only options with an AUTO trans..

Do you track the car with extensive power mod? If not, stay stock.

Driving the car during the winter does take significantly longer to reach operating temp. And you need to tape up the front grilles in sub zero temp if you need to drive on the highway for extensive time, since the radiator just works so well, that the car would actually have problem keep the heater running.

If you need DD the car, which I don't, it could be annoying.
