Radiator fan

[78F350]

There's way too many words in this thread for me to read, but here's a link and a pic to follow up the PM.
radiator cooling fan resistor values?



I've done this in 2, maybe 3 cars now and no failures after several years.

After seeing your very impressive rear quarter replacement on This (or That? I can't remember,) I'm more than a bit surprised you'd use a jerry-rig like that. Yes it works, but.... IDK.... seems like you're inviting electrical/corrosion issues. That's just me.

To each their own.

Besides, I don't think the resistor is his problem since he has to tap on the motor for it to run.

The .5 Ohm 100 watt resistors work just was well as the stock and have better cooling. I prefer them to ~20 year old used ones and pricing new Porsche ones at over $180 at Pelican makes the choice easy.

That does sound like a bad fan. I hadn't read through the discussion about the specifics, but posted here to reply with the pic of the resistors after Starter PMed me a direct question and linked me this thread.

I totally agree with you on that. And I have no concerns about the resistor itself. Living in the rust belt, I get concerned about corrosion with splices. Even with the best attempts with shrink wrap and all, around here you're just inviting problems. I've seen it.

In your neck of the woods it's totally different environment and most likely not an issue.

I bought similar resistors and replaced both of my old heat-soaked and worn out factory ones. (only 1 was malfunctioning)

Total cost was under $20, and 15 minutes installation including soldering and heat shrink. Didn't have to remove the inner fender either, access is easy from underneath.

They do not look like a hack job either, they look like an upgrade. You can search, I posted up my DIY a year or so ago.

BTW...If you're buying 1 new fan, why not do both with all new resistors? Then you don't have to go through this again...and it will likely happen. The factory resistors are prone to failure as they get old, and given their location.

Enjoy!

If I buy new it won't be OEM. What do you think of these?

I'm considering buying used from a local (75 miles out)... but they have 100K on them. However... I thought I might buy the used... and replace the resistors (like you did).

What would you do?

Buy those aftermarket pair for $110 or buy a used pair... I'm thinking I could get the pair for ~$75?

Thanks, and
