Thread: COOLING ISSUES... help

man, if you were closer danny, i'd plug my laptop into your car an we'd find out exactly what temps shes runnin at..

i wish bro. i wish. ok... so far... new thermo is in.... now bleeding it while at work.. temp is moving up a tiny bit . but thats it. if the temp is at the middle right now.... when i start driving it slowly goes down. is there a wrong way to install thermo stat? beside the lil hole thingy aiming up what else"?

It seems like you're not getting the OEM temp gauge logic.

If your temp gauge barely goes up, your temps are not barely going up. They are probably toggling from 212 to overheating and back.

And if your temp gauge goes down, it only means your operating temps went below normal.

(I've had dirt and oil on a perfectly fine sensor cause the needle to move around more quickly than OEM should)

The OEM gauge has 3 "settings" Cold, operating temp, and hot.

Cold is 0 deg and something like 150 deg.

Operating temp is (150 deg) to 212 deg.

Hot is over 212 deg.

----

If your engine is 170 deg. your needle will read exactly in the middle.
If your engine is 200 deg. your needle will read exactly in the middle.
If your engine is 185 deg. your needle will read exactly in the middle.

It may not look exactly in the middle, but it's in the same exactly spot close to the middle if everything is working as supposed to.

If your engine is 0 deg. the needle will be all the way to the left.
If your engine is 120 deg. the needle will be all the way to the left.
If your engine is 50 deg. the needle will be all the way to the left.

If your engine is 190 deg. your needle will not be "a little over the middle." It will be in the gauge's normal middle (which may be a little below the hash mark).

--

Furthermore, your needle does not start moving upward until the moment you hit 213 deg.
The only way to see this and have it make sense is to hook up something that sees actual engine temperature, not engine temp status. Like an OBD2 scanner or an Informeter or a Scan gauge.

Any updates ?I haven't replaced my sensor yet but I tried one I had laying around.same results ,at idle gauge reads halfway.driving it goes to C .

You replaced the single wire sensor? Is the metal tab loose on it?

STILL DOES IT OVER HERE.. LIKE LLAPRAD SAID could be oil seeping onto sensor distorting signal..

Start off with taking a temp reading of both coolant hoses on the radiator ... That will help u figure out of it's a electrical issue or a mecahnical issue ... Once u get that then u have something to work off of
