I was going to order a ECT gauge and was wondering where to mount the sensor. I have already used the port under the T-stat for the coolant filter. The gauge sensor is a 1/8 NPT. Would the block drains be a good location, or is there another location that will work.
I know the coolant filter housing has a port, but I would prefer the sensor be on the motor.
I drove my 99.5 7.3 F-350 1 mile to a friends and hooked it to the OBDII to get a code for my abs light.it had not been drove all day. we hooked into the pcm and he noticed the temp at 375* it was idling. is this right he didnt think it should have been that high???Will the engine coolant temp sensor, if it were bad,show a high temp of 375*? On the OBDII it showed a temp of 375* .....
View 14 RepliesPlugged in my ScanGaugeII on a whim, it's usually on my 6.5 Suburban daily drivers, but was curious to monitor a few things on the 7.3
Noticed this right away, coolant temp reading a solid -40*F and never budging.
Coolant temps getting much higher than oil temps under load. Is there any problem that could cause this other than a bad temperature sensor? Reading temps with an Edge CTS 2 monitor. Think I'm going to hook up a mechanical gauge in the morning and see what it shows.
View 8 RepliesNoticed a while back that the plug for what I assume is the air intake temp sensor is looped. I assume because I can't find the sensor anywhere. how critical is the sensor? The new S&B has a hole for it so it's either gonna need a new sensor or a plug. The local autozone has one for 16.99.
View 12 RepliesFor some reason my OH display decided to show 140 deg F when its 40 deg F outside. Continues to show 140 all the time now regardless of out side temp. In case its the related outside temp sensor sending unit, where it is exactly on an 02. Unless someone has solution may try changing that out to see if that is the problem?
View 14 RepliesHad coolant in oil, so pulled motor. Got used motor to replace it with, thinking about doing some work on it before reinstall.
Got bellowed up pipes, injector o-rings, front and rear main seal, and will use best parts from both motors to make one. I'll also shim injector armatures back to spec.
Should I do injector cups too? What else is recommended to do at this time? Both motors are 350k or so, I was on a budget at a moment and have to make it work with what I got.
Ok I have a p0197 engine oil sensor low.. Temperature is cold right now and truck was not plugged in.. Truck surges when started unless I give some steady throttle and oil warms up. Also service engine soon light comes on.. Oil change soon but been a while.
View 9 RepliesI have a late 03 f350 and see some relay boxes under the hood drivers side rear bolted to the fender, looking for a diagram of what those relays do,also one box has a 10a fuse. Also any have a fusebox breakdown for same truck in cab under steering with 4 plastic cover screws?

It has a lost of engine coolant. The oil is 100% clean with no signs of Coolant. No chocolate milk effect. Also it makes a Odd thumping noise at idle. I think it is coming from the Exhaust Manifold.
Bought this truck, and the engine coolant temp gauge does not work, so I replaced the sender, still don't work.
View 8 RepliesI have a sensor on the top of the engine on the driver side that has oil coming out of it. I think it is called an IPC but I want to make sure before I go buy a new one. It sits right behind the power Steering pump. I am replacing the Power steering pump and hoses so I thought I would replace that as well. Also since there is oil in the connection what is the best way to clean the connection electric parts cleaner? By the way this is a 2000 7.3 4x4 ....
View 11 RepliesEver since having the EGR delete done, the oil temp has been LOWER than the coolant temp. I am assuming this is bad info from the sending unit? They are reading with in a degree of each other at start up, but when at operating temp the gauge will read lower. Before the EGR delete I had a delta of about 4-7* oil hotter than coolant.
View 1 RepliesJust over 6000 miles....Yesterday morning the light came on. Dealer wouldn't look at it for a week. Went to my mechanic this morning to check the code it was p0181 fuel temp sensor. I read something online about the block heater making it too warm. The other night it was cold so I plugged it in, then yesterday morning it got warm overnight like into the lower 40s. I noticed the grill felt warm too. My mechanic cleared it if it comes back on do I have an issue? Is it ok to drive?
View 14 RepliesJust got my truck back (450) from rebuild on tranny. Hooked up my new obd link mx , and was out running the truck for a while. Started running it pretty hard to see what the gauges would do. Noticed the engine coolant was getting up pretty high, usually around 240-250, and then hit 270!!! My temp gauge on the truck wasn't budging , just stayed between hot and cold. Is this normal?? Seemed pretty hot to me but if i just took it easy on the throttle it would average around 230. If i stop and idle it quickly goes down to 206. Look at oil temp and tranny temp also engine coolant temp is bottom middle.

View 4 Replies2002 ford sport trac.I have been having an ongoing issue that started with the engine cranking but would not turn over until an hour passed. After replacing multiple parts (cam shaft sensor, crankshaft sensor, ignition pack) I am now down to poor fuel economy as the last of the issues (roughly 12 in the city and 15 highway). I was told the issue may be the engine coolant temperature sensor going bad so I decided to replace it. I found this was very difficult due to it being a plug and locking pin design and in a very tight spot in the engine.
I tried to purchase a replacement and the parts store kept trying to insist on selling me a part with threading. I finally found someone that figured out the issue and found the part for the 2001 sport trac had the same plug style with clip that did fit but was shaped a little different on the sensor end which I assume was due to being aftermarket. I noticed that there were two plugs side by side and the one easiest to access was on the left and I was told the one on the right was the sensor that gave the temperature reading to the gauge.
After installing the engine coolant temperature sensor I found the temperature gauge on the dash now will not respond and is sitting below the cold end of the gauge completely off. Is it possible this is because the part was for a 2001? Is the sensor on the left (passenger side) the engine coolant sensor?I would hate to put the old sensor back in just to test if that's the issue due how difficult it was to put that locking pin back on. What to check that could resolve the gauge issue before pulling this sensor back out?
So I got a 98 GMC sierra and the ect sensor that is on it only had one wire running to it. Obviously the previous owner tried to make something work. I bought a new ect sensor and pigtail to rewire it but can't find the ground wire anywhere. Looking for a wiring diagram?
View 14 RepliesI recently got the solid check engine light for my 2003 VW Jetta 1.8T GLS. I used a bluetooth OBDII dongle and Torque Pro to pull the code P0118. This seems to coincide with my symptoms:
Car idle at start in park stays around 1100RPM then in reverse it drops to 1000RPM then back into park and it stays around 900RPM and keeps that at idle.
If I start the car then immediately reverse out of my driveway then the car has a very rough idle but if I wait around 5 seconds in park idle then reverse out of my driveway it is smooth.
My car dash thermometer stays pretty close to the bottom low then after about 4-5 minutes it shoots up to 190F and stays. Gas mileage is also very poor.
I looked up a tutorial which shows the parts needed and how to replace the sensor : [URL] .....
I removed the engine cover and believe I found the coolant temp sensor in the spot the tutorial shows. My question is if there is anything I should be aware of before attempting to replace this sensor that this tutorial doesn't cover? I took a screenshot of what I believe is the coolant temp sensor.
My temperature has been randomly dropping, them back to middle, and recently my engine was overheating because I'm guessing the fans didn't turn on, because I'm also guessing, the engine didn't know it was overheating?
Anywho, during my replacement, I made sure to get rid of the pressure, and the car was cold. I tightened the cap again, but when I took the sensor out, all the coolant spewed out.
Now if I understand this correctly, do I have a leak? I figured the leak I had was coming from the temp sensor as it is.
Here's some pictures for those who'd like to see ....
