PostPosted: Thu Oct 16, 2014 9:30 pm    Post subject:  Radiator fan Reply with quote

My bearings went out on one fan, therefore always leaving a CEL so I won't pass emission until i get a new assembly, I'm confused if I need the Heavy duty one or does it even matter. also which vehicles are interchangeable.
I have a 2003 with the 3.8..

Unless anyone knows how to bypass the low circuit code, since pulling the battery and deleting it with the scanner doesn't work because as soon as I turn it over it pops right back on..

Thanks!

You might be able to bypass it with a resistor. It's a code, but not an emissions code per se so they might not fail you for it. For example, I have the infamous P0420 code with a high flow cat. They scanned it and listed the code on my emissions inspection, but since it passed the smog test I passed my emissions.

04-05 used a different radiator and fan. I believe the 00-03 used the same fans but I am not 100% certain...a quick check on AC Delco's website should tell you interchangeability. HD fans from the 9C1/9C3 should drop in fine, but you don't "need" the heavy duty fans if you don't want them. Instead of one high and one low wattage fan, the HD has two high wattage fans.

Never too late mind i dump the fan in the garbage



it's going to take 2 1/2 - 3 hours to install depending on your level of experience

these are fairly high amperage upto 12-14amps(At full SPEED) fans so using a resistor is not. going to work unless you want to start a fire
$89
http://www.ebay.com/itm/310703224125

has the Heavy Duty option and yes it works in normal car
The fan is fairly quiet and is not loud at all(I can't hear it from inside the cabin )
my friend installed it last night for me
in exchange for a part I bought for his car.



The car has not gotten passed the 1/2 mark and stays below it now before it was get to the 3/4 mark

The radiator changed in 04-05 and the mounting points for the fan assembly is different. From my research in looking for coolant pressure tester adapters, I think GM went to a sealed radiator (without a cap on the radiator) and the only cap in the system is on the coolant recovery reservoir.

I figured it would fit too five years ago and ended up buying a used 05 fan assembly for my 01 (since the 04-05 has replaceable motors) after one of my motors went. Turns out I was wrong. Wink

Correct. The Dorman assembly that retails for around $200 supposedly has replaceable fan motors. Might as well go for the heavy duty 9C1/9C3 fan assembly. Wink

If you want to go used, check the fitment on AC Delco's website for what years/makes/models are interchangeable then go from there.

The Dorman HD unit is still running strong in my Imp. Takes about 30 minutes to change out
