Well,
I took My fan shroud and some tinware off to fix a couple of leaks
Not bad leaks... one was engine oil from behind the fan housing and the other was ATF leaking from My ATF pump... neither were bad leaks...
But I decided to fix them in December once the temperature had dropped from 45C down to 35C and even cooler on some nights.
I was using a non genuine oil cooler sitting over the top of the fan
and oil was leaking somewhere where the hoses were tapped into the oil cooler adaptor.  Found it was a hose connection I had NOT tightened...
The ATF Pump has 10mm holes for the 4 bolts but uses 6mm bolts... so I found some Gaskets with 6mm holes in them and gave them a light coating of gasket cement... and filled the 10mm holes up with a red colored silicone looking stuff...
so far, there has been no leakage...  fingers crossed...

I have also fitted a new oil cooler that sits behind and above the rear RHS wheel. [drivers side over here]
I believe it should work great plus keeping all that heat out of the engine bay must be a good thing...

and  with the hot temperatures coming back and then very high humidity returned with a vengence .... Yikes...
so, its only been on the road for a few days...
its still driving like a beetle bought new in 1968...

I'm still very pleased with the way it goes and stops and handles..

Lee,
I would be a little concerned of debris getting in your cooler.

it would probably be a good idea to put some type of screen in front of it that you can remove and clean periodically.

Hi
Its to the side of the wheel/tire so its not going to get any debris like a mudflap...
and I placed it on the drivers side [RHD] so the wheel won't be going off the road and into gravel...
but I have been looking around for something that will let the air thru but stop any stones...
If I was traveling on gravel / unsealed roads I wouldn't have put it there... although I looked everywhere to see where it could be mounted so it got a good flow of air...

as My beetle is an autostick, I have an ATF tank above the oil cooler on the RHS rear fender and a Vacuum tank under the LHS rear fender... and not much room under there...
as the gearbox is larger than a manual gearbox..
and I didn't want to run the hoses too far...
although people have them under the front bumper???

cheers and thanks for the thought

Yeah.
I forgot about the limited locations for the autostick cars due to the added tanks lines etc..

I have run one under the front bumper before and worked almost too good so I had to add a thermostat so the engine would come up to operating temp.

another thought is to use a plate type cooler as they are more efficient and many times do not require a fan and they are much sturdier and can withstand the occasional stone hit.

I'm currently running mine beneath the transmision and it works very well. and doesn't hang much lower than the sway bar and I don't need a fan.

There are some compact fan powered coolers available out there that will fit above the transmission on the botttom of the luggage area. aircooled.net carries the sertrab ones but they require an type fittings and hoses

Hi
I have a small plate cooler [actually made in canada] but its too small.. maybe two or three of them would be better in summer..
I don't know if You know that the oil pressure relief valve only opens the oil passage to the oil cooler once the oil is hot and thin...
When I first added the oil cooler, I went for a drive around town at night and the temp was about 20C.... I came back home and the cooler was still cold... next day I went for a half hour drive in beetle in 30C temperatures and the cooler was nice and hot... lol
so, whether i need a thermostat in the oil cooler line, I don't know... could be good in winter here where the temp goes down to zero C in the mornings and overnight...
I can remember seeing those for sale somewhere>>
I also have collected a few fans over the years..
mostly still too large...  but maybe I could fit one near the cooler to blow air over it...
as most of My driving is on the highway, there should be enough air to keep it cool..
I have a temperature gauge to connect up too.

cheers

LEE in Australia   36C again yesterday..

winter is looking good... lol

I would definately install the temp gauge as it is the only way to really know what's going on.

Hi
Yes I have a temperature gauge in the dash and I have installed a temperature sender in the case of My 1500 single port engine.
this is where the dipstick was in type 3 1500 engines...

cheers

LEE

Hi
well I finally connected My oil temperature gauge uo to the sender
I've only driven it to the local shops when the temperature was 14C so the needle had only just started to move when I got home..
 Maybe today I can get it hot enough to see the Maximum temperature it gets on the highway..
it should work OK where the oil cooler is, and with the local temperature slowly going downwards...
No More 45c-40c- 38c-35c-32c- not even a 28c now...
and I'm sure I'll be using My beetle heater very shortly...
