Currently have a flat type three fan (rear housing on my baja twin port engine and was just wondering if an upright fan would keep the motor cooler or hotter?

The upright fan assy will keep the engine cooler.

The car creates a vacuum behind it as your driving along so the inlet for the Type 3 engine is right in this void so therefore its carnt suck any cold cooling air into the fan to cool your engine.

what about this. in a 1600 upright. does removing the rear tinware help cooling or bot? ive heard that people have done this in beetles so as to allow more air in from under the car...

Well it would depend if you still had the origional heater boxes fitted.

If there still on the car and its in a Beetle then removing the rear tinwear behind the fan will allow heated air from the heater boxes back into the engine and you would have hot air trying to cool the engine. This is not good. J pipes would be ok to remove the rear tin on a Beetle.


In a buggy if it had J pipes then this would be OK providing your not running a dog house fan shround again hot air is exiting the oil cooler and being sucked right back into the engine fan.

Ok in the splitty Do you have all the origional tin wear on

With the J pipes do you have the origional lower heater box tin that goes between the block and the exhaust ??

Does the engine have the cylinder barrel deflector plates fitted on the under side of the barrels.

Do you have a dog house oil cooler n fan and correct tin wear for this set up

Do you have a correct rubber engine firewall and rear tin rubber seal in place.

How do you know its getting hot temp gauge wheres the oil temp sensor???

Have you had a good tune up using a exhaust gas analiser to set jetting on the carby or carbies ???
If the engine is running lean this will cause over heating problems.

dont know whether it is because it is in a early bus. ie not enough vents. here is apic of the motor. you will notice a pipe now running air from the heater tube, via a vent set up up front. but this only helped a little. the other dayfrom wingham to taree. a trip of only 15klm. the temp reached 100 and the speed was only 90klmh. it was a hot day but an further and the temp would have just kept climbing.
we are tryng to find solutions.
thanks

Well it sounds good to me except i wouldnt run that extra tube as its picking up hot air from the oil cooler exit

I suggest also that you fit the lower tin between block and J pipes this may and will help exit the hot air out behind the car.

Thats a pretty big muffler you have sitting right under the cylinder head so possible heat transfere could be effecting that as well.

Heres another long shot are your brake shoes draging and are your wheel bearings running free. This would make you depress the pedal futher than needed to extract the same power out of the engine to get it crusing along.

In other words you may be pushing it too hard

Whats your compression ratio on the 1776 engine

Hope all this helps

the tube actually connects to the old heater pipe under the bus. might insulate the exhaust and pipe next and see what that does. no there is no dragginga nd stuff with the brakes. they are discs all round and sorted well.
thanks will keep posted under my own thread.
