Well
I have been fiddling around with different remote oil coolers for a few years without a lot of success.. well they worked sometimes but the engine bay still got very hot..
so, My Son had bought Me a new doghouse oil cooler a few months ago and has been asking Me every time He sees Me whether I have installed the oil cooler yet...  and I've finally done it...  as usual.. not without problems.. when I put the fan belt onto the alternator, I couldn't turn the fan belt by hand as the fan was hitting inside the housing, on the backing plate by the sounds of it..  I tried putting aluminium shims I made up under the alternator but it didn't stop the fan hitting the housing..
so, I had to lift the fan shroud up off the engine resting it on blocks of wood, so I could pull the alternator with fan attached out of the housing. The other problem was, I had taken the alternator to My Son to take the old narrow fan off the alternator and fit the new wider doghouse fan. He did this with an air powered rattle gun, removed the old nut and fan and shims and fitted the new fan and did the nut up tight.  So, I had to take the nut off the alternator and fit some more shims, and again, and again...  until the fan didn't hit the back plate..
Now. normally this wouldn't take too long to do, unless You are going to paint the tinware and doghouse fan housing a different color [after taking ALL the old paint OFF]
This one day job took a few weeks .. lol... I also had no idea what color to paint the fan housing and tinware. I had found some new EPOXY pressure can paint which was very tough paint, much better than the VHF hi temp paint I had been using.
anyway, its all done now and looks great...
Well I think it does... I do have to repaint the heater hoses...
and I've decided to do them EPOXY yellow too...
that decision took a few days too... lol..
You can't rush these things...  after having a RED engine and hoses for 5 years....  I'm looking at 10 years at least next time..lol..
Hope You like it....

I have driven My beetle over 60klm run and all went well, engine is staying about 90 degrees on My oil temp gauge. I also have a dipstick temperature device which switches on the oil temp lamp in the speedo when the temp gets high- lamp flashes- oil too High- lamp stays on- a wire connects this device to the oil temperature sender.  These are locally made in Australia. I check the temperature by looking at the top of this, as an arm moves with the temperature, and when too hot, the arm touches a screw with the wire attached.   I'm told Gene Berg used to make these years ago. a very handy temp gauge
I'll have to take a pic of it.. so far, no paint has burned off..   so it all still looks great... and is going great..

Winter over here has turned to summer..lol.. was colder in the coolest ever summer!!
 yesterday was 2 degrees off being the hottest ever May temperature recorded

cheers

Hi
thanks for the comment.
Well, its been over 5 months and My tinware paint is still OK
No peeling or cracking etc...  Looks as good as the day I did it.
and it has been tested... lol

in early August I was driving down the highway at 100KMH when the red lamp on the dash came on...
OIL TOO HOT

I pulled over and turned the engine off and went round to the engine bay and checked everything including the fan and the fan housing flaps which are normally used with a thermostat  [but I haven't fitted the thermostat as yet]  and found the flaps under the fan shroud had closed which cut off the cooling air... 

I  also found the piece of wire I had used previously to connect the temperature sender caught in the fan...
along with the piece of galvanised wire that held the flaps open... lol

so, basically it was My fault for running the sender wire near the fan opening and for having the wire joined [soldered] with a piece of PVC tape over the join...   the PVC tape was probably a bit unstuck and was sucked in by the fan... taking the piece of galvanised wire holding the flaps open with it...

it was all fixed in a few minutes..

a few days before I had found a small piece of wire going to the engine oil temp sender.. but the remainder of the wire had just disappeared.. lol   
so I replaced the wire and connected  it up again.. lol

You can see the flaps at the bottom painted white

Well, I have done some miles [or klms] and apart from the cooling flaps shutting twice causing the oil temp light to flash plus the extra light on the dash [which I did notice]
when I painted the fan shroud I  don't know where I put the spring to hold the flaps open..
so, I took the fan shroud off last week and refitted a spring
so the flaps will stay open now..
My engine is still not going well.. It will do 80KMH but not sure it will go any faster|??
going by the timing light its only advancing to 20 degrees instead of 40 degrees it was doing before..
I'm guessing now I may have an air leak..??
I've taken the carburetor off twice and although I use gasket cement, I'm not 100% sure it sealed..
starts and idles perfect..??

Well, My beetle will now do 100KMH on the highway and 90KMH up hills.. it may go faster but that is what is allowed locally. I have put My timing lamp away, it was driving Me nuts , so I just timed by ear.. lol and did the mixture when the engine had done 40 klms, so at least no popping in the exhaust etc. so its a goer , and reliable, but I know I need to pull the carburetor apart again, as I'm not sure everything is OK there. There is a lot of inducted noise from fuel spraying into the carburetor throat. a very loud spitting noise??

summer is coming - although 2 degrees C the past early mornings it will be 32C on friday.
I need to fit those side pop out windows
