Hot climate - extended sump?
Hi all,
Was wondering, here in Kal, it gets over 40C constantly during summer and would an extended sump help to control engine temps? More oil would help
disperse heat better?
I could be totally wrong and happy to be schooled!

More oil means it just takes longer to get hot
If anything an oil cooler is what you need / want
In / out on the oil pump is easiest
Make sure your tin is all in place and you tune correct
A stock motor driven normally should cope with a hot day

It doesn't make much difference to the oil temperature when the air temperature is 40c..
Greg with a beetle, I recommend having the top of the engine lid open using either the readily available alloy hinge STAND OFFS or I use the steel
bracket that is made from welded flat steel and can be installed or taken off in less than a minute..... so the top of your engine lid is open about
75mms approx.. and this does make the engine run cooler in the summer at 40c... with the air coming over the roof and into the engine bay... I have
vents in My engine lid so the hot air can also get out....
You will also see many early engine lids with two sets of vents in them, which was original in early beetle cabriolets, but all those You see will
have been made up. Now if Your engine is still a single port with original fan and housing, You can change to a later wider fan and housing plus the
wider [larger] oil cooler which will help keep Your engine much cooler than the originals. Do You have any pics of your engine?
My 1968 model beetle had no vents in the engine lid, but later ones did, and also was a single port engine [still is] but now has the later fan shroud
with new wider oil cooler and wider fan etc.. called a dog house fan shroud as the oil cooler sticks out from the back of the housing...
Make sure that the very hot air coming out under the engine cannot get back into the engine bay and getting sucked into the already hot oil cooler
The rubber seal around the engine bay needs to be in good condition.

Hi Greg.
Lo-40s for a few months in summer? Is that all? When does it get hot? 
Only joking man!
It's a different world with high temps and low humidity, it raises ALL temps as you know. A few tricks I've used over the years, in order of proven
effectiveness against CONTINUOUS running on the highway.........
1. A big ugly 80s whale tail. Makes a HUGE difference. Bloody ugly though, stand-offs are a pale substitute, but maybe prettier.
2. A water mister kit, like your patio has, aimed at the fan intake. Drops ALL temps, including oil (coz the surfaces don't transfer as much). Spray
for a few secs, wait a minute or 3, spray for a few secs, etc.
3. Extra oil cooler with a fan, but it needs cool airflow without any red dust or gravel thrown at the oil lines, so a bit tricky.
Best of all?
Keep the revs 3000-3500. If it still gets hot, then drive around at 75kph in 3rd, heaps less aero load but max air cooling.
Finally......park it up between 8am and 6pm maybe? 
Mine (hopefully......) will survive at 100kph up and down rolling hills in mid-hi 40s, into the usual 20kph headwinds, with less than 8% humidity,
while towing my dragbike on a 6x4 trailer if all the tricks work.
Hopefully.......

if you are running a 1600 in an early beetle you WILL need more air in there
Hood Jax work a treat

Guys
Im curious. Why do the 80s style whale tails make such a difference?

I have actually fitted a scat deep sump to my 2l kombi some years back. I tow a 400kg trailer with sup board on roof to Byron over Christmas so
expect temps up to 35C. A deep sump does make a small difference and I am glad I fitted it. But it won't solve chronic overheating issues. And
yes, I have been running an accurate (at 100C) oil temp gauge for the last 5 years to compare and all tinware and muffler heat shield is in place.

They do help slightly.... and every degree that drops does help.
Worthwhile - Yes...
plus You can get a proper engine oil filter to sit in the extra sump.
