Re: Radiator advice, please!

Hi I replaced my X/9 radiator with an alloy one from Alfa 33, slightly smaller in surface area but is deeper, Dropped engine temp by 15 degrees, and never over heats thru mountain roads. Can be found cheap on eBay. Had to modifiy bottom mount and add top bleed hose,

Re: Radiator advice, please!

Hello, I have fitted dual fans at one point.. It is true the second fan needs a secondary relay triggered off the temp switch and a second power wire installed from the battery. It works ok but what I found was these stock motors on the fan draw a termendous amount of current which draws and loads the alternator quite a bit then resulting loss of power. What I ultimately done was aquired a Marelli motor out of a Lancia fan which I had installed on the stk X19 fan support brackets.. The Marelli fan (used also in vintage Ferrari and Lambo's) is very efficient and quiet. Another thing to check as well is the water pump flow. Pumps are known to get weak in pressure overtime and will flow well with higher RPM but flow not so well when idling.. there is over 11 liters of coolant to push around in the X19. I hope this may shed some insite on your dual fan question.

Re: Radiator advice, please!

Hello Breeze2

many thanks for the input there. I have installed the second fan and motor (am glad i did that before installing the new radiator) but have not connected anything to it yet.

Yes, I was worried about the feed wires also. I was thinking to uprate the relay and the wires from there to the junction where the two fan feeds separate.

The draw on the alternator is worrying: measured when running at 12-15A each with an initial much higher cut in spike (measured at 75A!). I say this is worrying because when the single fan cut in the other day i immediately had rough running. This happened twice in succession. However those more experienced than me say that it was merely a coincidence.

cheers

Re: Radiator advice, please!

Hello pal

I really enjoyed your video! very well presented and produced!

Can you post details of the fan please?

Does it have a greater current draw than the original? I was going to fit two original types, ie add another to my new rad set up, but think youir set up is better

Also, I see you were using what looked like a factory manual which I'd like to track down also. Could you give me any details please?

If you have done other videos, i will look forward watching them too.

Keep up the good work, that video was inspiring.
cheers

RDS

Is the one you are look at the same as the ones from ebay?

The siroco rad, I just had a search on ebay and they all seem to be from germany, but very cheap.

Might be too late but could help someone else perhaps.
Its A fair time ago i last had an X1/9 but i did find that if the idle speed is set at about 800rpm then at idle the water pump wouldn't move the water well enough to get the hot water to the front rad and hence turn the fan on, the result was over heating in traffic. setting the idle at about 900 rpm was just enough to move the water to the radiator.

might be of some use to some other car models too

Re: Radiator advice, please!

that's a good point timmy, thanks. its a long way to the front of the car and the rad.

When I get over the over-heating coil issues, I will check but recall that i set it to around 900-950 also because it gave a more stable tick over anyway.
