how high can be the oil temperature at a 36hp engine?!°!?

oval56

hi, i have now tested my oval, but as a type 4 engine only driver, i was a little bit speachless as i looked at my oiltemgauge by drivening about 60-65miles/ hour and my oiltemperature goes up to 230°F - 250°F (110°-120°C)

i thing that it is a little bit to high, so what do the oval 36hp enginedrivers normaly have

my engine is new rebuilt ( crank cam , bearing oilpump) but it have a judson on it, and also i have an extern oilcoolter mountet instead of the original ( mounted on rear torsionbar)

any suggestions?!?!

Hi oval56,
230F you really do not want to get to. Personally we prefer to keep the temp below 220F. Backing off on the gas as the temp gets above 212F.
Check your oil temp with a gauge type you can get the sender down the dipstick. Candy thermometers have to be very accurate, and are inexpensive. Test the test gauge with boiling water at somewhat near sea level or boil temp adjusted for higher altitudes.
The oil cooler with no fan is not going to work well. Better to get it back inside the shroud in a doghouse to give it better cooling.

Congratulations, you have just proven that replacing the stock oil cooler inside the fan shroud with an external one makes the oil temp go up. Rip out all that crap and stick a stock cooler in the shroud.

If you think you want more cooling, use a Porsche 356 oil cooler. They are the same size as a VW one, but are aluminum so they dissapate the heat better.

Hi I have just put 500km on my freshly rebuild 36hp engine with Judson, in the last week, and I have mounted a 356 oil cooler on it, and when I am cruising with 100-110km/h the oil is 70-80 degrees celcius.

It is not aluminuim (in fact I have never seen one in aluminuim) but it have wings/baffles like a radioter on a modern car or newer oil cooler, I had it tested and the guy said that it would be about 50% more effective than the original one.

Here is a picture from the rebuild, but it is a little difficult to see it properly.

I am also rebuilding the motor for my 54 bug and am wondering about using the 356 oil cooler mentioned above. Is their a specific year 356 oil cooler you use and are any other mods necessary to use it .Thanks

okay, thanks for all that ideas, but my idea was it to replace the stock cooler, to get the headtemperature at a low level , so now i will try a 356 cooler instead of my extern one or later plus my extern one Smile

Hi Troy
Yes it just worked out fine Smile

Thanks again.

rlmatinez The only mods I needed to do was to hammer the inside of the fan shroud a little, as the 356 cooler is a little higher.

As for which year it is ask Teeroy he is the man I bought it from.

56oval Anothother idea could be making a fanshroud with a dog house oil cooler, this way you still get good coolin on your heads, I was thinking on doing so on my own.

I am surprised that the motor didn't seize up! There is a reason that those crazy German Engineers put the cooler INSIDE the doghouse. The internal one combined with the external one would probably lower temperatures, but I bet you wont get past 1000KM without it developing a leak somewhere. Just my opinion.

I am only kidding I understand you perfectly no need to destroy the new engine Confused

I was thinking is your type 4 not getting hot when you are holding still?
I have several frinds that driving with big type 1 egines 2276 etc
but they all have a doghouse oilcoolers and a seperat front mounted oil cooler.

Another thing is are 100% sure that your gauge shows the correct temperture? My nos motometer unit had to adjusted when I put in the car.

hi peter,

my gaues are nerly perfekt, i use the same in my 56, and they both have a difference about 5 degrees at 120°C, so they work perfect..

my type 4 engine has only the frontoilcooler ( setrab) , and when i drive to the meetings, my speed is 140-160km/h at 3500-4500 upm constant, the oiltemp goes to 100°C ( if it is hot outside the maximum is 105°C), cylinderhead goes at this speed from 140-160°C, also nearly perfect...

berfore i will reach oiltemp higher than 110° i had to slow down, becaus the cylinderheadtemp will go higher than 180° ...and 180°C is my stop point Smile
