Engine oil cooler?

since the ICE doesn't run all the time, and a lot of folks are blocking the radiator with no ill effects, I don't think an oil cooler is necessary. I would suggest using the best oil and filters you can get your hands on. I think amsoil claims their oil is good for like 15K. and someone here has found a larger filter that fits; that might be a good idea too.

 

You may be accessorizing for nothing.
The question is what is the engine temperature and what is the engine oil temperature?

What symptoms make you think you need more engine cooling?

Maybe some no cost accessorizing would be to remove the grille/ anything blocking air intake to the radiator.
Keeping the radiator/ ac condenser area free of leaves and debris.
Perhaps placing some NACA ducting in the undercarriage fairings/ plastic shield panels to gather air from under the car and move it to the engine compartment.

Quality synthetic oil, extra large oil filter are good ideas.

Oil cooler, many options, cost...$400?

Good luck in your decision.

 

welcome! you might want to invest in a scan gauge to watch rpm's and temps. how many miles on your car?

 

wow! all the best!

 

Derale Stacked-Plate Engine Oil Cooler Kit w/ Sandwich Adapter (Multiple Threads) - Class III Derale Engine Oil Coolers D15605 has thermostat so it does not 'cool' cold oil (180 F)

Derale Stacked-Plate Engine Oil Cooler Kit w/ Spin-On Adapter (3/4-16 Threads) - Class III Derale Engine Oil Coolers D15651 if you want to relocate oil filter

While I question the need for an oil cooler, these will not cool when unneeded so should not harm anything.
They sell cheaper kits with no thermostat, but I worry they would hurt efficiency. Derale Tube-Fin Engine Oil Cooler Kit w/ Sandwich Adapter (13/16-16 Threads) - Class III Derale Engine Oil Coolers D15503

 

Yeah wait a sec, there's already a REALLY serious cooling system in the engine: glycol coolant, big radiator in front, maybe sleep on it?

 

It is his money to spend, I am just trying to make sure that he does no harm. Everyone has different needs to spend money, at least he is not asking how to make his car louder. He just wants to be cool. Now cooling the transaxle, that would be hard.

 

From my experience with past cars cooling the transaxle makes more sense than cooling the engine. I had a Volvo s80 which would have its transmission fail due to overheating. The fix was a external cooling method.

That may help the prius, but I somehow doubt it

 

With a VERY small oil pump and no filter, it would be hard to tap into the transaxle to get ATF under pressure. I think you would need an external electric oil pump.

http://www.summitracing.com/parts/til-40-524/overview/ That is way more than the entire kit for the engine. The Prius transmission may make far less heat than one with a torque converter. (One reviewer claims this pump is louder than his race engine. "In a gutted race car with just a pair of Flowmasters (no tips or tail pipes yet), you can EASILY hear this pump over the running V8 and exhaust noise")

The existing oil pump in the transaxle is briefly mentioned here at 7:35 to 7:55.

And can be seen here from 5:05 to 7:10

 

wrong, the fix was to send that POS Volvo to the scrap yard. a Volvo is a urinal with wheels.

 

All I've ever heard with engines is get them UP to optimum temperature, as efficiently as possible, and then the engine coolant, rad and fans deal with any overshoot. An engine oil cooler seems a fool's mission.

 

Radiator (engine cooling) - Wikipedia, the free encyclopedia

 

Because it is not a highly stressed engine typically, there is no oil temperature sending unit or even an oil pressure unit except a digital 'good enough' and 'boy you are in trouble' switch. adding a oil temperature gauge to find out if you have any worries may be cheaper than starting with the idea that you need a cooler.

This non thermostatic sandwich adapter is drilled for an oil gauge sender and if you need to add an oil cooler later, it is drilled for that. http://www.andysautosport.com/products/spyder_auto__ACC-032-SL.html

Here is a Gauge in Fahrenheit with a sender, all you need if you know a place to insert the sender in the Toyota engine block. Amazon.com: Dewhel Oil temp temperature Gauge Universal Meter 7-Colors LED Smoke 52mm 12V 120-300 °F W/ Sensor: Automotive

 

Hahaha. We used to be a Volvo family. After ford bought it it became utter crap. Basically the s80 fell apart one piece at a time. Never again.

 

You may want to consider an oil cooler once you determine that the temps are consistently staying above the norm. The manual say's 87C is the opening temp of the thermostat and that is about 185F give or take a few.. I couldn't find anything about the oil temp tho.

With the ELM327 and Torque app you can probably monitor those temp while staying in a low budget range before buying any additional cooling system.



I actually don't know if you can control the fan speeds with the torque app in the genII but with Scangauge I believe you can manually control it to help with the battery temps. Others have added inverter coolers when noticing high invertor coolant temps..
