Fan temps

Shamrock

Hi guys can someone post me the fan temps that should be inputed while doing my uprev tune? I have the gold series oil cooler. Now ambient temps of 65 (winter here now; in the summer a min of 95) the car takes half an hour to reach 170 with regular driving after installing the oil cooler. When I really jam it the temp max is 200 (now in the 'winter') in the summer probably higher. I have k&n intakes, stillen headers, and akropovitch full system. It's kind of annoying that it takes the car a while to warm up and I can't have fun on the way to work. Do you guys still recommend the fan? It won't prevent the car from reaching normal driving temps? It will just keep the temps lower when driving temp is reached? I never track the car and drive it hard every so often. Stop and go traffic is pretty serious here. Thanks.

Do you have a thermoswitch on your oil cooler so it does not fully open until 180?

It sounds like you don't have a thermo-bypass on the cooler. You want to bypass/block flow through the cooler until the oil warms up.

The ECM starts limiting power somewhere around 190F, so you want your fans on max a little before that. Play with it until you find a good setup. May have to tweak it a bit as seasons change.

No thermostat.

If you mean you removed the thermostat from the engine, then that's your problem with slow warmup. Put the thermostat back in and see what happens.

I think he means no thermoswitch (thermostat) on the oil cooler.

You really need to have a thermoswitch on an external oil cooler on a street car. I highly recommend the Mocal one.

I didn't remove the thermostat. I had to order the cooler from the states. I am over seas. I could get a thermostat now after installing the cooler system? They don't sell anything here in Israel. I would have to wait a month for it? Is it crucial to have the thermostat? I don't drive hard until the car oil has reached operating temperature of 180. You say to fiddle with the fan temps but I don't think anyone is competent enough to do that here. There isn't a standard set-up? Like thisImageUploadedByTapatalk1356977662.006514.jpg.

Those Uprev fan settings are fine.

Maybe one of our venders can get one for you but I bet you could order from Europe easier. Maybe from demontweaks??

Dr., what are the implications of driving the car w/o it? Does it cause damage? What would the installation demand in terms of work? For example, could I put it on the current system without any add-ons? Would I need to cut the the oil hoses? Which one from mocal would you recommend for a daily driver? Thsnks

I would try to keep coolant temps below 190F (ie, max fan at 187 or so) to keep the ECM happy, but I'm no expert. If that map is recommended by someone that knows what they are doing, go with it. You can always adjust it later.

As far as the bypass, you can get by without one temporarily, but baby the engine until oil temp gets close to 160F or so. It may help to temporarily block part of the cooler (a piece of cardboard works well).
I try to keep RPMs below 2000-2500 until the gauge moves off the 140F mark. When it gets to ~160, I'll let it rev to 2500-3000. I try to keep a moderate foot on the pedal until 180F. This is being very conservative - the oiling system can probably handle WOT once oil temp is above 140F or so. YMMV

The implications are that your oil stays thicker for longer. This is probably okay if you use a good oil and don't get on it until it is warmed up but it also means your engine makes less power and uses more gas while the oil is thicker.

You need the Mocal Sandwich Plate- 20mm Thread MOC-SP1FT
You just replace the plate you already have with the Mocal one. You might need fittings or adapters depending on what your current plate setup is.

What is this piece? I have the stillen gold series oil cooler and it came with this piece. They call it a thermostatic plate. ImageUploadedByTapatalk1356981218.168102.jpg

That's it! Install it.

Edit: If you still have slow warmup after installing the oil cooler bypass, check the thermostat on the engine; it may be stuck open.

It is installed. I took it for a drive now 1/3 traffic and 2/3 open road at 55 ambient temps. First pic startup after 10 rest

It seems that once the needle starts climbing after 15 minutes or so it continues to move up at a much greater pace but stops at the last pic. Your lowest needle mark is 140F?
