I would get an aftermarket mechanical temp gauge if you want accuracy. You could look for a plug in the block or head that goes into a water jacket and install and don't even worry about the factory stuff. a higher thermostat is a good idea, as is putting some cardboard in front of your radiator, if your engine isn't getting hot enough. Cardboard is a good one, cause you can remove it easily in the summer.

 

i actually just replaced my heat sensor and sending unit today with BWD parts, and my heat gauge works now!!! :D the old heat sensor was corroded as hell and gonked up with carbon and gas and all that nice stuff and the sending unit was just a little corroded, not too bad, i think that's it may even possibly be a reason behind my bad gas mileage.


So justin, id check the heat sensor and the wire, you could posslibly even see how the colant looks, i also replaced mine (agian) in the process.

No specific brand name thermostat just with a higher temperature settings. Usually a 195.

 

well thank you jt, but liek i said, replacing the heat sensor and sender fixed it, at least in my case, but if i have future problems with the guage i wil deff look into that

 

You could always buy an aftermarket water temperature gauge, then from there watch the numbers. I'm pretty sure that these run at 180 Degrees?

 

Sometimes its the Needles inside the instrument Cluster it slips. I changed my needles from the stock white to the red ones from a crown Victoria. I just had to move each one by hand to dial it in. My temp gauge is actin up right now, and I don't feel like opening up the cluster again. I was just thinking about putting a gauge pod with the temp engine gauge in my truck to fix the problem but never did it before.

My question Is what size fitting do I get for the temp engine gauge( the fitting is already mounted to the gauge right?. what size will fit my engine. My truck is a 2002 ranger xlt 4.0 auto. and where does it connect to? have a pic where it connects to?-thanks

 

Same thing here got plenty of heat just gauge won't rise much..Also when i move the ac control from anywhere beyond full cold(on the red and blue colored dial) it will blow hot lol. So its full cold or full hot nothing in between lmao.

 

When you guys get the no heat or little heat and the needle that climbs up just slightly you should check your water pump impellars. Mine where GONE! ....... corroded away! It doesn't hurt to take it out and look. If anything you just have to replace an Oring if its still fine.
