cooling fan again!

[califkid_66]

went to a car meet and track day and europa was overheating so noticed my fan was not working properly i decided to take it apart to see what was wrong when i took it apart water came out and spring was gone and the push tab for the brush was rotten
having limited tools and no parts i used what i could find i used an old bottle cap witch i formed into the pivot and wanted to used a hair elastic to pull on the pivot but realize i had a spring in my pen so used the spring and it worked !!
i it felt like in the movie apollo 13 when they used what they had to fix the problem and make it home
safe

Nice "MacGyver" job!

Very clever!

The Renault engines are very reliable and will take a lot of hard driving.  BUT, they do not like to be overheated.  You have a 60 year old fan that you have cleverly cobbled together to work again.  As the darn thing didn't exactly blow much even when new, it would be a very good idea to change it for a new HO fan.

Well sorted
Plus one for JB's suggestion

thanks for the comments i am looking for a slim fan but im going to rebuild the fan motor before putting it away with the original parts i already got the new bearings but i realized that some parts have improved over the years and it would make sense to use them i drive my europa the way it’s supposed to be driven so if a more modern fan is better then why not thank again for the nice comments

The modern thin/slim fans do not move anywhere near as much air as a "thick" fan.

The modern thin/slim fans do not move anywhere near as much air as a "thick" fan.

Surely the modern fans rotate faster than the older fans.

Do they have a cubic feet per minute rating? That would seem to be the way to measure their performance.

There is quite a bit of the radiator not covered behind the fan. Large rectangle - the circle = uncooled radiator.

me to i thought more cfm better cooling im wondering how many cfm the original fan was
do you have ny specific fan in mind that could be better than the original
maybe a stupid idea i had was put a fan in the rear grill to push out the heat from the engine compartment im getting tired of having it run hot

[califkid_66]

would this be a good replacement for my cooling fan it’s a push fan

That area behind the rear window is a low-pressure area to pull the heat up out of the engine; a better idea would be to put fans in the grilles on the boot lid to extract heat from the engine...the rear grille only really exhausts heat surrounding the muffler and tranny (which really doesn't  (or shouldn't) get as hot as the power unit.

This fan should work for you, 10" pusher fan according to Amazon. I'm using Spal 10" fan 30102058.

[califkid_66]

the one with more blades is 649 cfm and the one you have is 1115 cfm
i like the one with less blades looks more like the original one and seems to flow more air
a bit more expensive but if it prevent overheating i getting one !!
for the fan in the engine bay i don’t think it’s gonna be nessesary with a good fan in the front

Just be aware that the five bladed fan draws a bit more current and should be accounted for in the relay and fuse protection.
