Hi Folks

I fitted a new [made in USA] oil cooler under My RHS rear fender
[drivers side in Australia] and I was wondering about the oil temperaure. I have had a VDO oil temp gauge [50-150C] in My dash since 2005.. but not connected... lol
I have also had a new oil temp sender inserted into the type 3 dipstick plate.  Driving around Town at night the temp didn't get off 50C.. So, I drove 30klms to the next town and the temp went up to 120C  YIKES... and over 120C on the return trip..
I thought I had a major problem with the location of the oil cooler
but I was asked by a VW mechanic [on a forum] what temperature gauge I was using...  150C or 120C ..?
well I was using the 150C [for water cooled engines] I should have been using a 120C gauge, which I also happened to have in My spares..
 So, I fitted the 120C gauge and the temperature doesn't go much over 100C out on the highway...
EXCELLENT....

The oil cooler is connected to an adaptor on the engine where the original oil cooler was...
and the single port oil pressure relief valve only lets the oil thru the oil cooler once the oil has gotten hot and is thinner and lower in oil pressure..

well,
I changed gauges to one that went to 120 degrees C , but it still went to 120C at 100 KMH on the highway...
so, not enough getting AIR thru the oil cooler..
I'll have to fix that tomorrow...

Yes
its getting down to 7C degrees at night and in the mornings now and not getting over 20C in the daytime.. which is about 10F & 65F degrees..  I've never got used to the Celcius temperatures.
I'm lucky I can drive most of the year , no snow or salt on the roads here.  I usually tend NOT to drive in the summer over 36C degrees.. about 90F degrees. [max 42C]
as its just too hot.. to drive without air conditioning..

the past summer wasn;t too bad , only about 30 HOT days but sometimes We get Very Hot days in November - December January and February and some of March... 
We had a nice cool day at Christmas this year... so, long shirts jeans and coats could be worn... instead of no shirt..
AS it gets so cold here [-4C winter mornings] the heater in My beetle is welcome.. but many people don't fit the heater boxes..
I find it nice and warm driving My beetle in the cold with the heater on...

Well,
I have lowered the oil cooler down about 2 inches and it has made the world of difference..  Maximum 100C degrees
and most of the time around 80C degrees...

so, I now know the oil cooler has got to go lower into the airstream ..  before the summer...

Winter started officially on the 1st June....
although it has been cold the past month.... but getting colder..

no minus -C temperatures as yet...

cheers from Australia

Lee

I lowered the oil cooler down more and the temperature doesn't go over 88 C degrees....
I am going to fit the oil cooler I bought many years ago
it was a kit ...cooler adaptor- oil filter adaptor- fittings - so, I'm looking at bolting it under the chassis... and may fit/make a scoop to catch the air..
see how it goes..
before the summer arrives..

Hope you didn't burn it up, no oil is kind of hard on any engine. Did you if notice the oil light had come on before you shut-er down. Good luck to ya Lee I know that this is not the kind of problems that you want to have at the beginning of your summer.

Hi
well....
I still haven't restarted My engine...
I really want to get it passed for the yearly registration.. so I will have plenty of time to work on it...
it seems to have plenty of compression..
checked the tappets and they were spot on.. and turning the engine over by hand was just as difficult as before..
I believe I've picked up
[by the crankshaft] the Big end [conrod] bearings..  which seems common with overheating due to no oil..
I didn't notice the oil light... Will have to make it BRIGHTER or another EXTRA bright one for daytime use..
The temperature gauge didn't go UP..
I always watch it... I saw the oil on the highway yesterday.. where it happened..
when I pulled off the road.. a small trail leading to the Pool of oil... where I stopped.. so fingers crossed..
Its also getting Hotter over here.. 36C yesterday.. 35C today...
will be too hot soon to work on the car...
[normally at this time of year] but the weather is very changeable now..
Had a couple of 16C days recently..???

Hi Folks
welcome to the New Year...
Well, I have great news... I had no damage to My engine after it lost all its oil..on the highway..
When I lost power [just before the hose came off] a spark plug cap had come off.. [down to 3 cylinders]
that's when I looked in the rear vision mirror and saw blue smoke.. [the hose was loose and spraying out oil]
when I stopped.. the hose came off.. and all the oil came out under the car...  naturally, I didn't know this for about 8 or so days, when I had to get My car passed for the yearly registration and roadworthy certificate.
I accidently found the loose spark plug lead... lol
and then put together what had happened...
You can be Very lucky at times... lol

cheers

Summer is now here 36.5C today but nights are still under 20C... nice nights for driving a beetle..

Well, its summer here sort off... Coldest January for 20 years..
I have been driving My beetle around town a lot and the occasional drive to a town 30 miles away. On the way home My oil temperature gets to 100C which is too hot I believe..
especially as the temperature hasn't gotten over 31C the past month [instead of the normal 40C++]
My Son bought Me a new doghouse oil cooler , so that is the next thing to do..

Well, after all that, I have fitted a new doghouse [twinport] oil cooler with wider fan and new fan housing. its running much cooler than before, so VW did know best when it comes to cooling and oil coolers. lol..  I also painted My engine tinware a different color , and I used Killrust epoxy spray can paint, it seems to be much harder and thicker than the VHT paint I had been using. also much shinier..  I don't think the paint had anything to do with the cooler engine temperatures.. lol

Lee in Australia - summer in winter over here.. 26C YIKES..
