Ford 7.3L Power Stroke (1999-2003) :: 2002 - Oil Temp Of Block Heater - 56 Too Low?
Oct 24, 2015
I wanted to specifically ask about the block heater though. Since I bought this truck I never was able to start the truck without plugging it in. Now that it's not running I'm thinking much more about the block heater.
Is 56 too low for this old truck to start? What temp should a block heater have the oil temp as seen by AE be?
I live in the southwest so it's not very cold here. plugging in the heater was even required in the summer unless the truck had been running. What kinds of engine trouble would require being plugged in in warm conditions?

I don't think that my block heater is working correctly if not at all.

I can't get my truck to start. The block heater isn't working and I previously put flush and water in it, intending to drive it and flush it directly after. Well I never really could drive it and now it won't start again. The weather is going to turn off cold, around zero this weekend. I need to know how to keep the block from freezing and cracking!

What the coolant temp should be around after plugging in the block heater overnight? Not looking for an exact measurement since this can be affected by OAT and the length of time it has been plugged in. But when it's -15 to -20F this weekend I was wondering what to expect.

When the block is cold my truck will not start. If i keep the block heater plugged in it will crank but is still a long start. I have tried just about everything i can think of and it is way too much to list so i will give as much info as i can.
New- gpr, glow plugs, HPOP, batteries, starter, fuses, valve cover harness/ injector and glow plug wiring, vacuum lines. I have checked out just about everything remotely possible.

I didn't have time to trouble shoot but heres my problem. I plugged my 2016 6.7L in last night and when I checked it this morning the block was still ice cold. I didn't have time to investigate but i did make sure i had power up to the truck. And i noticed there's a connector just after the truck plug as well.

Does the block heater come with some kind of a cord? I found the Box Link stuff under the back seat finally, the dealer said the block heater should be under there too? But it aint there?

I have had this happen twice now. Starts fine, idles fine, then either sitting or just driving a block or two it starts running very rough, no smoke that I remember seeing, and now no power. Barely makes it up a hill. The first time I thought is was related to the heavy rain the night before. I had the tow truck coming and decided to try it again, this was after a few hours sitting. Ran perfectly. The second time, no wetness/rain, pulled away from the house and in a block or two, same thing ... rough, no smoke, no power. Pulled back into driveway, turned off for a minute, restarted and ran fine. Ran perfect today. What is the best injector cleaner to use in the fuel?

Don't drive the truck but once a week but since its gotten colder here than usual is been harder to start when cold. Of-course I go thru the glow plug wait and then it kinda stumbles when its about to start. I do it again and most of the time is starts but seems rough for a few seconds. Once the truck is warm, no more problems starting.
I'm wondering if I have a glow plug gone bad and that cylinder is not warming up for me. Today I plugged in the block heater for maybe 2 hours and it started first time. Also, if just leave the block heater plugged in for long periods of time.. would it get to hot?? and wonder how expensive that is, most heater are costly to run. I have a timer but just wondering.

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.

Well, I swapped a 2011 F250 SC for an F350 CC and I really enjoy driving it. 300 miles on the clock. My old 250 had the block heater and the pigtail to plug it in was low in front of the radiator. This truck also has the block heater, but I cannot find the pigtail to plug it in. In 2016 where Ford hid it at?

Ok, is it possible to blow a fuze if the block heater is still plugged in when starting? Almost did this the other day and wondered if its possible to cause a short or something.

Is this common? No coolant in the oil-YET........
Any way to fix it without pulling the cover?

2002 7.3L SD ... He told me when he was taking his son to school he turned on the heater. When he did this he could feel the truck lose power, he turned the heater off and it drove fine. Turned it back on and power loss happened again. I haven't driven it to test yet or see what is happening but I also don't understand how this can happen. The heater did get warm, and he does not have to add coolant to the system.

The heater fan stopped blowing the other day. The fuses check out ok. What would be the most likely culprit after that? relay? Switch? Blower motor?

I notice my trans temp gets really hot fast. For instance just moving my trailer from front of my house to side yard makes temp go to 250. Without any load and driving a couple miles it does the same thing. It's been doing it since I installed the trans temp gauge just trying to figure out what's up.

I've searched, and gone back through my computer history and can't find it. I have seen a thread here which Mark contributed too which said what the max temps were and for how long etc. I know book is 230 and optimum is around 165 but there was some degree of play in that.

2003 CC 4x4 ... I am pretty sure I know what is going on, but I wanted to start a thread for when I confirm it. I am driving to work this AM and I hear the door ajar chime and I think to myself, uh oh...gauges all look good, there are no lights illuminated on the dash. I get to work and turn the truck off and my fan stays on. I think the ignition module is going bad. Either that, or my remote start is going on the fritz. I will update when I find out more.

Heater control will not adjust, the one in the middle. I can turn it up and down, but it doesn't affect how much heat the heater is putting out. The other two work correctly. Do I have a bad switch or is the blender valve sticking? How can I tell? '99 F350, 1.25M miles.

Noticed 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.
