2L golf motor in microbus

[caravelle]

Jaco

reading this sounds like the 2l conversion is better than the V6, i have a 1991 Caravelle that had the 2.1 motor in when i bought it and was pretty happy with it used to two carravan ect no problems then head bolt went took motor out an stuck it in the corner, had a V6 in a older model kombi that had been scrapped so took the motor out and stuck it in the Caravelle being that i had everything already but have never been realy that happy with it i feel the 2.1 had alot more low down torque ect, have never used it to tow since putting in the V6 just dont seem to trust it, would you say that there is a definate improvement to the V6

engine den in pta has the 2lt import motor for 4500 ..ask for a guy named toy.

Golf alternator is internally regulated, hence the two wires.

Type 4 alternators are externally regulated and have those extra wires...

thanks Blitz!!

I have a 1979 Crew cab with a aircoolled machine which I want to convert to a 2l Golf watercooled machine. I do not want the rediator to be visible. Where is the best place to install the radiator. Can someone give advise and also what radiator will be the most suitable.

do you guys think it will fit in a split bus?

i found some pics when googling kombi conversion cooling system ....

they had the radiator under the bus built into a secure casing ...

they say it works well but i dont know

that is somthing ill be trying anyway !

As I am doing a waterpumper conversion on my bus, I have done extensive research on radiator placement. Up front appears to be the best, but I don't want to spoil the looks of my bus. Under belly rads work but the have pros and cons. Getting enough airflow over the radiator could pose a problem, as well as getting rid of airlocks. A few guys had success with radiators in the back,but all of them in cooler countries than here. I developed a system to fit the radiator in the engine bay with enough airflow over the radiator. Yet to prove it works as the bus is not running yet. BUT Beware! It involves a lot of cutting and welding.

Air flow is the same as water flow.
You have to make a path with channels for the air to flow.
As You cannot get water to flow up hill with out a pump, you can not have air flow where there is no Duct for it to go.
If you look at the new cars, you will find that the air intake is a 1/4 of the size of the old cars.
This is because they make a passage for the air to flow, from the front of the car, via ducts, channels, passages for the air to flow to the radiator, through the radiator(not stopping here) but along the ducts to the outlet at the bottom or back of the car. This means you can now place the radiator anywhere you like as long as you follow the points above.
On top of this, they create a scoop, so that it creates a vacuum at the outlet of this air, to help PULL it through the system.

Now this is what I based my system on. The only thing is you will not get enough airflow over the radiator, as the air intake on the side is just that. An air intake. What happens here is that the fans draw air through the radiator,but blows the hot air over the engine. There is now way for this hot air to escape. This will gradually heat up the engine at highway speeds. You have to seperate the heat the engine generates, and the hot air through the radiator. This is achieved by ducting, like herman said. A blow through fan will work better in this case fitted behind the radiator. I used a 1600 golf radiator. The small pipe that normally comes from the is cut of and blocked. Tapping it 6mm and putting a bolt in with some pratley steel works fine. If anybody is interrested in how I achieve enough airflow over the radiator, I will start a thread with details and pictures.

i had a chat with a guy @ sylverton radiators ....he explained that the best radiator that should be used in somthing like this would be the Old vw Caddy radiator ....He has explained that most race cars and hot rods use those as they can cool most big engines with ease !

hi iv done this one two of my buses and it works well u more then
welcome to come and have a look im in centurion. i have no problems
at all.

both have under bell rads

[oldschoolgp]

Any pics ???

[kts customs]

esh no time will try

Under a bus in South Africa would probably be the best idea where you don't want the nose cut, airlocks can be a problem, but you'd just have to do your homework on bleeding points..........I don't see a engine bay mounted cooling system being that effective.

Have a look on this site for some great bus information with water-cooled motors in air-cooled vehicles.

Anyone who thinks that putting a water-cooled set up in an aircooled vehicle is a simple affair, then think again, stuff has to be planned out and if you're doing it yourself there is a lot of trial and error. Unless of course you pay for someones knowledge who has done it before.
