Permanent Solution to high oil temps??(Not an Oil cooler)

acdHQK713K · 01-10-2012, 11:27 AM

So how can I get my old water pump to fail so I can get this new one under warranty?

Pour some molten lava into your coolant expansion tank....

That would be cool. Although on RealOEM the "newer" pump is still only assigned to the N55, with the "older" pump still listed as being the latest model for the N54.

I'll be able to confirm that however when I get my car back tomorrow, as the water pump has just been changed. I'll look up the part number and report my findings.

Alpina, let us know!

Power it with jumpers to a couple hundred volts!!

FWIW, Turner Motorsports also lists the new pump for all N54 and N55-motors.

I have the STETT OC without thermostat. It takes about 3-5 miles driving or 5-10 minutes at idle to record an oil temp (170). I live in Dallas so generally no an issue, but on cold days I just keep it below 3k rpm until I see a reading. A small PITA but well worth it for no issues at the track in June. Change my oil every 5k miles.

e90pilot · 01-10-2012, 02:07 PM

Anyone have a picture of the pump? Just wanted to know if it fits an N52. The parts diagrams show the same picture but the real part might be different. I'm having possible water pump and T-stat issues. Might be worthwhile to upgrade mine as well if it fits. I'd probably have to still use the N52's T-stat though (Plastic).

You need to put your thermostat back in. The oil thermostat serves the purpose of maintaining a pressure differential between the two sides of the oil cooler. Without it, you have essentially bypassed the oil cooler.

Not applicable to the STETT configuration, the "no-thermostat" option for STETT keeps the flow open to the OC at all times, hence Ultraracer's comment about taking a while to warm up. I have a Stage2 STETT OC with the thermostat and in the Northeast it takes about 20mins of driving before the thermostat opens at 180F, at 30-40F ambient.

This confirms my suspicion that water-to-oil cooling is much more effective than air-to-oil cooling. Combine this new N55 water pump with the bigger radiator fan from the 335is/1M, you could be running around the track all day.

Doesn't the BMW Performance Power Kit come with an additional water radiator and new fan? Dinan also increases water pump speeds with all of their tunes.

You still have to have evidence vasil.

Oil temps take forever to hit 200-210F, but water warms just fine.

170? Jesus, in city driving, it takes at least 20 mins, maybe more.

Whilst it may be fine for tracking or when you live in very hot climate, you won't get the engine to operating temp quick enough in cold climate, increasing wear.

Are you confusing water, with oil thermostat?

Knowing how cheap they are, you probably won't, unless you mention it specifically. They're still peddling remanned early N54 water pumps.

Just wanted to find out which Tstat you have. It seems like Behr (Plastic), and whaler(Aluminum) make the current thermostat. The one I pulled out was made by BMW in germany. These Aftermarket Tstats are at 97C. I wonder what mine orignial one was at? It was metal. If the one you have came originally with your car or was put in at the stealership, then it might be an OEM one made by BMW, and thus, have the same operating temp as my original one. This would explain why your temps are high.

What do you guys think?

Dinan researched this and found that technically there is no need for the second radiator. BMW added a tiny second radiator to midigate for the small OC in the 335is and the PPK.

Since the primary radiatory fan is now larger and beafed up all that is need is a larger OC, and remove that tiny secondary radiator for a CAI

From the paperwork its the newest pump and T-stat (plastic one) but it does not end in "A"...Mine oil temps stays around 240 during the summer and in the winter when I beat on the car it goes to 240 but hovers around 230 when driving normal...I wonder if the "A" makes any difference??

I made a mistake! The one that was taken out was aluminum but the new one is cheap ass plastic
