Can the temp. sensor on a 2003 be replaced with a Stewart Warner gage setup? Will it effect the computer? Thanks.

You got several answers at RVNET on this -- looks like the iRVers are sleeping on this one.

Why would you want to disable the stock gage when you don't have to? Just screw the S-W sender into the unused sender hole on the other cylinder block.

fatman...
whaddya drivin? plz add some info in your signature box.
if u have a gas eng you can use a scan gauge 2 to get a digital readout of coolant temp as well as about 20 other parameters.
i got mine from mileage pros...
it works well.

Mahlon, don't really trust the gage that came on the rv. It has such a wide range on the gage I would like one that is more accurate. I posted this over on RVnet, but the answers over here are answered by folks that seem to have more knowledge then some who answer over there. Some seem to give infomation on topics and shouldn't be...enough said..

Fatmanobx,

Do like DanL told you.

Get a Scangauge II. Plug it into your "on board computer" (near the steering column- under the dash on mine) and your done . Digital info is all there, including tranny temperature, engine temperature, throttle position, Horse Power, Torque, RPM, MPH, oil pressure, vacuum, etc, etc, etc. Its a great tool. Go here to Omeys site, call him, He'll send you one all set up.

Go here to see To see more on this wonderful instrument. It'll cost about $180-- Well worth it!

Good luck,

Like Mahlon said... get a scan gauge or an Interceptor. Both just plug into your OBDII port and give you all kinds of neat information. One good one is you get transmission temperature.

No, that wasn't my point. It just seemed to me that you were creating work for yourself.

The cyl heads on the 8.1L engine are identical in all respects, including the pipe-tapped hole for the temp sender (one side has the sender, the other side has a pipe plug in the hole). Just screw your new temp gage sender into the unused hole and don't bother messing with the stock sender.

Mahlon · 12-04-2008, 06:25 AM

Oh, another thing: a Scanguage will simply give you a very precise readout of whatever the stock temp sensor is putting out, along with whatever inaccuracies go with it.

fatmanobx · 12-04-2008, 12:20 PM

Thank you all for all the great responces. With everything else that can go wrong on these things, I am going ahead and buy one of the scan gauges and have all the info mentioned at hand. Thanks again, Ron

fatmanobx · 12-04-2008, 12:37 PM

Just ordered my Scan Guage and it will be here in a couple of days. Thanks again to all and maybe this will make me more at ease. Thanks, Ron

DAN L · 12-04-2008, 02:28 PM

MAX...
there is no oil pressure readout on my scangauge.
LINEAR LOGIC, the manufacturer, says that they are working on that and to keep checking there website about new x gauge functions.
my coolant temp runs from 197-202 deg. wh and brazels say that is normal.
