135i Cooling ?

Hello everyone,
I have owned a 135 for about a year now and this is my first post. Thank everyone for sharing their knowledge. It has been very helpful. As you know our turbo cars generate more heat than na cars. I have not had any issues, but would like to improve on this.I dont track the car, but do have fun on the back roads.On hot days and heavy traffic I notice oil temp rising. I have thought about the BMW PPK which would add a stronger cooling fan and a additional radiator. Another up grade would be a larger oil cooler such as DINAN that is about twice the size of our stock unit. Has anyone with either of these upgrades noticed any improvement?

Water is the primary cooling agent for the internal combustion engine. What you want is additional water cooling and not oil cooling. With better water cooling you will see lower oil temps as well. Not to rain on the oil cooler manufacturer's parade, but that is the fact. Until water cooling issues are addressed, you will only see minimum drop in oil temps even with larger oil coolers.

What ranges of oil temps are you seeing and at what temps outside? Typically I see around 240-250 at the very most during hard driving in temps above 80 degrees. Usually when the ambient temps are lower and im just driving around usually its at 230 average. I have the HPF intercooler and DCI but no tune yet so..

BMW Performance Power kit stage 2 if you want to keep it "factory". It incorporates a mild tune (equiv. to the iS N54 cars) along with an improved radiator, bigger fan and additional water cooler. Excuse me if I missed anything. A number of places have it on special at the moment for USD1,200.

Be good to just get the PPK fan & water cooler. Wonder if they can be sold separately?

For the PPK the main radiator is the same/untouched 135i part. The PPK only adds an aux radiator (tucked up into the drivers fender area) a higher wattage(stronger) radiator fan, new spark plugs and the SW tune (+23 Hp or so).

Any one know what oil temp the electronics safe-guard kicks in and limit the engine power? I think it is 130 degrees??

Thanks everyone for your input. During nromal driving I dont exceed 250.This is with the stock tune.I thought that with an after market tune the higher boost levels would be generating even more heat.However it seems that it is not an issue with most folks runing a tune. Looks like the best option to assist cooling would be the PPK version 2 since it has special pricing right now. Thanks again for your thoughts on this matter.

Larger radiator and/or BMW Power Kit(additional water radiator and high output fan).

Yeah, I wouldn't want to get involved with meth for engine cooling either. Good call.

You could run a 80/20 Mix of distilled water to coolant, with a bottle or 2 of water wetter. That would reduce both engine coolant temp, as well as oil temps. This would be the most economical "mod", and you are going to get the biggest bang for your buck. If you not tracking your car on a regular basis, you really should not need to have any additional cooling beyond this.

I think the ECU goes into overtemp at 280 deg oil temps.

Apologies if this is a dumb question, but are there OEM or aftermarket larger radiators for the 135i?

I have been looking for one, but can only find applications for the 335i, I don't know if they swap over though.

So how does this work, u just drain all ur coolant n then add distilled water and that water wetter with less coolant and blamo im good? Not sure how to drain coolant nor which coolant works best

Also, any link for where to get this "water wetter"?

Simple drain and fill.

Ya not id wanna drain all my coolant. Couldnt i just add half of that to my coolant already in the tank. Hopefully it wouldnt cause an overflow or something.

Yes you can add water wetter to your current coolant without draining anything. It wont make it overflow. While it will help, having more water .vs anti-freeze will result in a larger drop in temp.

This post will help explain water wetter, and using a greater concentration of distilled water vs coolant a bit more:

This is not a snake oil if that is what you were asking.

Lots of pro race teams use this product with proven results.

Do an online search and you can find it for yourself.
