SR 5 Speedo Cluster Question

bentyota · 01-08-2007, 11:06 PM

I have had a few tries at this one. DOH! I did the usual. With the first try, I pluged in the cluster with the wrong oil pressure sending unit. One down. With the second, I put what I thought was the right oil sending unit in. Had low oil pressure, found out there was a different oil sending unit, put it in and wa la...good oil pressure, but the water temp read half way on a COLD motor and never really changed. Gave up, put the stocker back in, ended up throwing that cluster away. That's how it stood for a couple years, then I got a "hair" to try again. Just put another SR 5 Cluster in and guess what?? The water temp reads half way on a COLD motor AGAIN??? Any ideas...oh and yes, I searched!

On a *completely* cold motor? Or luke warm?
The temp sensor seems to be electrically dampened.. It's "normal" for it to jump to the "normal" range 1-2 minutes after starting the truck... Or at least that's how it behaves on my rig.

X2,I was wondering if mine was bad.The other day it was low on coolant and finally moved.

i think the toyota system holds so little coolant that when its low things like the heater doesnt work or the coolant temp sensor. at least thats how mine works or doesnt depending on how you look at it.

i have a 85 sr5 so if theres anything i can look at for ya let me know. sometimes i forget how lucky i am to have a 85 sr5 efi xtracab

Bob Garrett..it's an 85 with A/C.
dcg9381...on a completely COLD motor.
My stocker didn't do this, so I wouldn't expect this one to. I'm gonna give up for good this time. Stocker going back in. Thanks

i had one that did that...but after you drive it for a little it would go back to operating temp...

from what ive herd they like to stop working. I have a sr5 dash in mine now and if i tap the dash it works once ina while. i tried checking all the connections and its just broken. My stockie works fine. I am about to get another dash very soon. I need the pressure sender, soooooooooo ye they just break an when there f`d they stay at whats "normal"

I tried this a long time ago myself. Had pretty much the same result. Temp and fuel is enough for me. I bought a guage to put under the hood for oil pressure. It's still in the box. I put a shift light in as a joke and my jackass roomates put a 3000 RPM pill in it so I know when 3000 rpms hits and I'm blinded, thanks. These engines run pretty well no matter what. If its low on oil press it knocks a little. You can hear it.
