DIY cooling fan fix?

My 05 LGT is out of warranty (37,000 miles). Is there a way to fix this problem without Subaru replacing the ECM? Like maybe removing the fan out of the circuit, and installing your own relay that is energized by the temp sensor? Any thoughts on this, would be appreciated. I don't think I stand this noise this fan makes any longer!

theres a TSB on it so im pretty sure it doesnt really matter if your outa warranty

What I am really worried about is that I've done enough to my car to void the warranty, including AP. I can reflash back to stock, but the ecu will throw engine codes as soon as its driven. I really don't want to put all the old parts back on just to take it to the dealership. So I'm just trying to think of a fix I could do myself.

I believe that Subaru's factory scanners are NOT ABLE to detect flash programs by the AP. Search for a post by whitetiger, he used to be a Sube Factory Tech, who had his car scanned by his dealership pals and the car came up clean according to the scanners.

Even so, the car will throw codes as soon as they test it with the new ecu. I guess what I'm saying is I would rather just find a fix on my own instead of reverting my car back to stock. Besides it seems like people who've had their ecu replaced report the problem coming back.

wwhat new ECU are you talking about? they wont replace the ECU its a mechanical fix...from what i remember they replace the relay...nothing related to the ECU

Since the fan fix has nothing to do with the mods done on your car, I'd suggest asking them to do the fix and nothing more. Tell them you'll handle the CELs later - you just want the new relay and replacement ECU.

 

They don't even need to test-drive it after the swap - just make sure the engine runs.

sorry im dumb...i guess they do replace the ecu, dont forget to unmarry your ap before hand

There's no way you can fix this problem yourself. The only people who reported the problem coming back after ECU replacement were those who didn't also get the re-designed relay replacement.

 

Luckily, your ECU is covered for 8yrs/80,000mi by the Federal Emissions Extended Defect Warranty. The relay, though, is out of warranty but you can just buy that part and install it yourself, in conjunction with the ECU replacement done at the dealer.

 

Make sure you un-marry and bring all your ignition keys when you bring it to the dealer.

My fan is running again. I had my ECU replaced already for this but I guess they didn't replace the relay with the newer version. That's annoying...

I was stage II, but they fixed it anyway. Divorved the AP, used the resistor for the uppipe and a mech fix for the o2 on the downpipe.

Jim, it took over a month for Subaru to recieve my new ecu. So I'm finally taking it in this week. Can you tell me what kind of Mechanical fix you used for the o2 on the downpipe. Thanks

Check with Rallitek , They sell it and are a vendor on the board. They are local for me in Portland . I havnt been down to them since they merged with ipd .

has anyone had this issue and taken their car in, with an aftermarket exhaust?

 

i know they can't say that it caused the situation. and i know they have to prove it, but has anyone been given trouble by a dealer for this kind of thing, given that it's a known issue with the car (TSB)?

I ended up removing the Perrin tmic and flashing the car back to stock a couple blocks away from the dealership at a gas station. I was worried that if it had an engine code showing that would say something about it. What really suprised me was that after picking the car up later that day, I drove it for two more days without reflashing with the cobb stage two program, and never recieved an engine code. Thats driving for two days with a Perrin downpipe, uppipe, and axleback and not getting a code. I wonder if one of the service techs did me a favor and changed something so I wouldn't get a code.
