Radiator

[DaveyB]

If I fit the merc 190 radiator to cool my 2.0 litre pinto, will I still need to fit a electric cooling fan ?

any help greatly appreciated

Hi Davey,
I would say yes with no hesitation. You will get a much better control of the cooling temperature in any conditions.
And you can get rid of the ugly original plastic fan from the Pinto, which is a must

I have a Mercedes 190 radiator, and I fitted a 12'' fan. There was an electric fan control on my engine (2.0i DOHC), so I reused the wiring and it works perfectly.

For your Pinto, you will have to add an auto fan switch.

Some pictures of mine:

Hello DaveyB,

Have a look at this short movie. (I did remove the radiator protection)

Last week the engine ran first time after installation. After a few minutes, temperature and pressure was so high that the pressure vessel burst open, squirting a couple of liters boiling water at me. Smile off my face and severe wounds to both hands and my chest. Could have been worse though.

What we think that happened is this: When the engine turns, the fan is spinning but at a certain point the thermostat/clutch of the fan should have engaged but didn't. So temperature and pressure got far too high, resulting in the bursting.

Note that the mercedes 190, 2 liter radiator is mounted directly in front of the fan, as in the Sierra.

Is that with the Pinto fan still in place - or are you wondering if you can run with no fan at all?

I don't think 'no fan at all' is really an option - unless you are going to use the car for track only and stick some sort of cooling system in place outside the car after a run - e.g. attach a fan to the front of the car in the pits (like they do with F1 cars for example)...

Wasn't really sure about the fan thought maybe leave existing and see how it performed, thanks for the help will now look at an after market electric which will be more efficient.

I think if i remember Ash G had a problem with pipework coming a drift and having some nasty burns certainly be quite a moment when first starting i'm a long way off that

Thanks for the help

a raidiator is just a heat exchanger and needs air flow to transfer heat to the air to work
you will need a fan to move air when your staitionery

my merc rad is working very well with a fan and only cuts in in jams and coolent tems drop back truning fan off as soon as im moving 20mph and up

Thanks will make sure I add a fan

Thermo switch in the pipe to control remote elec fan is probably the easiest.

I have MB190 radiator and like Voucht I bought 12" universal fan...

But... be carefull - my fan don't fit my radiator. Or my "replacement" radiator has different inner sizes or my 12" fan is bigger than Voucht's.

As my fan is 297mm I think that Voucht fan is as they call it 11"... or genuine MB radiator is little bigger. So guys - look out.

Now my turn for questions...
I need to grind a little of fan housing, but it's not big deal...





Question is... how to fit fan. Should I use "yellow" mounting points or "red" ? Or maybe both ? Or turn fan 90 degrees and use 4 mounting points like "red" ? I don't like the idea of mounting to the core of radiator (it's chineese)
"Yellow" mounting points fits nicely to sides of radiator (can't see this on photo) I need to know before housing grinding...
Are the two mounting points enough ?

Have you tried the fan on a power supply yet. I was surprised how powerful mine is and it tried to spin around on its own.

I would have said 4 fixings is needed. I used the push through core fixings which seem fine on my polo rad. Can you not drill a new hole further in on the yellow fixings and attach to the core?
