Ford F-150 - 1997-2003 :: Sensor Broke In Cylinder Head?
Oct 7, 2012
I have a 1999 Ford E150 4.2l. My cylinder head temp sensor was dangling but still connected to the sensor... the connector was loosed from the filament but was still connected by exposed metal pins.
I figured I would replace it like i did to my ECT by the Water Pump. So I pulled the connector out and it started to leak...a little. and when I put the socket on it I instantly broke the sensor flush with the Cylinder Head.
I researched on here and found many people believe the CHT gives info to the Dashboard Gauge and the ECT is used by the ECU. I thought that was correct because I had ECT readings from my scantool...and my Dash Gauge never worked. When I found the dangling CHT I figured it was never working.
So I JB welded CHT hole. figuring i would fix it properly later. I replaced the ECT and expected everything to go back to normal.. No gauge reading on dash and a scan reading with no codes.
I want to replace the CHT sensor properly. Do I HAVE to remove the manifolds. Or do you think its safe to drain the coolant and drill it out. Its easy access. Im worried about all the tiny pieces getting into narrow passage ways.
I am almost 100% going to drill out. Manifold sounds like hell and its getting cold. What sensor controls what? Can I drill it out safely?

I have a problem nobody can figure out. My check engine light is on. Took it to Advance to have it scanned; came backwith Code 1226, Brake warning light ground short ( not concerned that at this time); Code P1285, cylinder head over temperature; and P1299, engine overheating (this repeated 4 times).
Now for the symptoms: Truck start and runs good, except with engine light on, runs about 4 miles, then the temperature gauge goes all way up, oil light come on (But oil pressure gauge is OK), Have loss power, and heater has no heat. I shut key off, restart, runs perfect, gauges OK, heater OK.

My wife is talking to someone about purchasing a 1998 4.6 4x4 EB Expedition. The owner says the only issue is a tick coming from the driver's side head. He claims the shop told him it was "just a cam stator". Now, say what you will, but I've dabbled just enough with mod motors (2v and 3v, 4.6's and 5.4's) to feel like I'd rather stick to old pushrods. I've never heard of a "cam stator" on a 2v 4.6. I also realize that stator is a word that gets tossed around a bit by people who don't fully understand what it is.
Now, this is a relatively high mileage engine (something like 220k I think) so I know it could be a whole slew of things from cracked/leaking exhaust mani, lifters, timing chain, etc. But, in all my searching, "2v 4.6 cam stator" keeps leading me to people troubleshooting pushrod distributors, 3v VVT troubleshooting, and alternator related posts. Is this such a thing, what this shop may have been trying to refer to? He claims it's done it for about 5 years now, and runs perfectly fine. I'm leaning towards lifter, but the truck is 3 hours away so I haven't got to check it out yet....

Ok I got this truck from my mother-in-law for free with a blown head gasket cylinder 6 driver side. I did the replacement had the heads machined put it all back together by the book. Now I can't get it to fire on all 6 cylinders only 5 I think. Thought maybe bad gas (it sat since late November) put 5 gallons (over double the gas) fresh gas and half a bottle of b-12 chem tool. Dubble checked all plugs wires connections (coils plugs wires all new). I drove for about 10 miles oil pressure and temperature stayed perfect but no change in running truck shakes a lot and no real power. Don't sputter or backfire no engine codes other than imcr bank 2 open. Engine is 4.2l v-6 170k miles.

Well i had an exhaust leak on this F250 and so I started torquing the bolts on the manifold to the head. (45 ft.lbs) A couple were very loose so I was thinking "Great, this may fix my problem!"
My first mistake was probably the Harbor Freight Tools torque wrench.
I am on the driver side, second from the rear and then bang! I see a gaping hole where the bolt used to be. Bolt on the floor. I cant see up in the hole to the head, I think it broke flush with the head.

(The truck is a 05 f250 with a 5.4l). The problem first started out with the engine temperature gauge spiking and then resetting itself when the truck is turned off and then turned back on. If I drove the truck for any distance it would go into limp mode and the CEL would come on. The code was p1299, which is the cylinder head temperature sensor, and I replaced the sensor but no luck. Then the shop and I went through all accessories hooked up and couldn't find a short until I remembered that my prodigy break controller would occasionally read "ol" or "sh" which both readings are from shorts. I tow a enclosed trailer about 85% of the time and the past week I have been towing it with a different 250 and the same break controller without a problem so I have eliminated the trailer. But the shop just said the problem was the controller and unhooked it.
Now the next day it threw the same code with the controller unhooked and the trailer hooked up. after thinking it seemed that it was happening when i accelerated so I took apart the 7 pin and sure enough there was a little water in it, but after driving it around for a little and no code being thrown I hooked my break controller up and it still was showing ol or sh so i believe there is still a short. Also I noticed that my voltage is reading right at 13v instead of the 13.8-14v it was reading before this issue arose. I think I have narrowed it down to the 7 pin harness and/or electrical in the break components, but do not know what would loop back to the temperature sensor.

I was attempting to replace the front abs sensor on my '03 Excursion 4x4 when it broke off inside the hole. I tried grabbing the plastic surrounding the magnet, but it just kept breaking off. How I can get it out?

Do I leave rods disconnected? If not how do I make this work without the delete?
Will probably modifiy later on but need truck back running right now have a load to deliver MOnday

I have a 1997 Honda Civic that I was given by an elderly neighbor's daughter after the elderly lady went to the grocery and ended up 100 miles away when she could not figure out how to get home. The car was smogged at the beginning of the year but when I got it ran very rough and the temp went nearly to overheating on the drive home when I was stuck in stop and go traffic.I found the radiator fluid level low and an oily residue inside the radiator water bottle. I took it to a mechanic to check it out and was told it had a blown head gasket and maybe worse.
I am thinking of buying a rebuilt cylinder head and replacing it myself but I am not sure how to diagnose if any other damage could have been caused to the engine. It's hard to know but I am guessing that the engine was damaged during the 100 mile road trip due to low coolant level. It turns out short term memory loss was the diagnosis for my elderly neighbor. I filled the coolant level and ran the engine for a bit and the temp stayed normal but the rough running remains. The oil dip stick shows no signs of coolant in the oil and the coolant looks bright green when I looked in the radiator after topping it up with some water.
Any way to detect if I could be facing bigger issues like failed bearings? I am OK to do the head replacement but an engine replacement starts to get into the realm of what it would cost to get another car of the same age.

I have a 01 f150 4.2L and a while ago the ac compressor clutch broke. I didn't catch it in time and the stress it caused on the belt broke the power steering pump pulley. So I replaced the steering pump and pulley and the compressor the accumulator/dryer and the office tube put the 134a back in and everything worked fine. three months later ac stopped working. I figured the condenser was bad so i replaced it. Charged it up still no cold ac. so i thought maybe the manifold that goes on the compressor was clogged so i replaced it. While I did that i said to myself well i should tear out the dash and replace the evap as well. so just about everything has been replaced on the ac system.
Aside from the cycle switch and the high side switch witch from my test both seem to be working. now here is the thing. the tube witch holds the office gets ice cold then goes to the evap but the suction line coming from the evap doesn't get cold and the ac blows warm air. this very problem is what convinced me that the evap was clogged and needed to be changed witch is why i undertook the task of tearing the dash out. in all it took 14 hours to do the whole job. now for the pressures that i get from the ac manifold low side goes 40 down to 20 ..... this is normal. high side is a little high. I charge it to 125 still no cold air. so i dump a little more 134 in. at 90 degrees high side pressure should be around 200ish i get it there still no cold air. I have just about replaced everything i can think of.

I went to unscrew the radiator drain plug but the head broke right off leaving the rest of it inside.
I drilled out a little bit of it so I could drain the coolant and bough a replacement plug but there are still pieces stuck inside and I cant get them out.
Should I just drill out the remaining pieces or is there a better way to get them out?

My rear-end differential came apart and is not repairable. I have a 1997 F150, 2WD, 4.6L engine, 5 lug wheels. Which years have the same rear ends so I can scour the junk yards for a replacement?

I have an oil leak where the HPOP hose attaches to the cylinder head. I have the removal tool for the hose. I assume I need a new fitting. What's the torque spec for this fitting, and any additional tips I need for doing this repair?

After replacing most of the underside of my Super Duty, Complete front end, backing plates, brakes, rotors and shocks, I have a misfire code on cylinder #4. I replaced the plugs, cleaned the MAS and filter and rotated the coil to cylinder #1. Still have a misfire on #4 and noticed the coolant slightly low and some condensation on the oil cap. Could this be the intake gasket? My mechanic is away for 2 weeks and I think the price at the dealer will kill me. I have 63K on the truck, don't tow and plow mostly family members. It's getting a little rusty but is still in good shape.

Is this job worth doing as a preventative maintenance item? I replaced the rear fuel rail plug (aka banjo bolt) o-rings because they were very easy to get to with the up-pipes out. But the cylinder head plug in the rear is pretty high up and even with the up-pipes out, there isn't enough room to get a breaker in there that's long enough and has enough movement to loosen it. The front would be easier to get to, but both accessory brackets need to come off to get to them on both sides.
As far as I know, none of them leak but they're all 17 years old... BTW in case you haven't been following, I'm doing up-pipes, injectors, turbo, rebuilt HPOP & fuel bowl, boots & clamps, etc. so I'm trying to knock out any PM items while I have it apart.

My truck broke down on the freeway last night. I heard a cracking noise (metal breaking) and it sounded like a backfire. The engine was running fine, good RPM's. I rev it up and the noise got worse, It sounds like a bad lawn mower or go cart. I was also smelling raw fuel.
Could I have broken a exhaust flange or the manifold? It sounds like the exhaust is bad and not burning the fuel.
There were no codes or a check engine light. I only went 1/2 mile after it broke down. I had to tow it to a local shop.
It's a 2003 4.6 with 205,000 miles.

I'll be working on an 03 camry this weekend with a small oil leak coming from the alternator and headers area. I know For sure its a gasket that will need replacing but which one and how difficult is it? On the last pic there's a blue circle ;the leak is from that area.....

A local mechanic tells me I have a blown head gasket on my 2003 Saab 9-5. He also said there's coolant standing in one cylinder. If this is due to stretched head bolts, might I remedy the problem by replacing the head bolts and torqueing to specifications?
