Early 4.0 engines (like yours) had a known issue with pinhole cracks in left cylinder head. This required replacement of the head whenever a head gasket issue cropped up. If you’ve been driving around with no coolant chances are there is already damage done.
BTW, what kind of a mechanic doesn’t catch low coolant when they are inspecting a vehicle?
This is where im willing to bet I let it slip my mind because when i got it back from the mechanic he told me a whole bunch of stuff we had to do and a bunch of updates on it then something else happened and i was back the next day and I think it just slipped our minds. But I have complained about it getting really hot twice now and they said “well it’s an old engine” So I think it completely slipped everybody’s mind that we had no coolant. It really sucks though!
If the fuel pressure regulator is failed and it is the cause of the excess fuel consumption, then it is probably flooding half of your cylinders with lots of fuel to the point where it is only running on half of the cylinders, and that’s why the over heating wasn’t as severe. It’s like it is running in limp mode.
No backfiring just a knock in the engine when it’s cold. What you are saying about the truck running with half the cylinders sounds like exactly this truck though. Now my turning signal just went out and I really don’t want to get pulled over and have this thing taken off the road by a cop so im trying to figure out that problem!
In the other thread you started concerning the turn signal switch you stated you took it to Midas. What did you have them do?
Midas does not have a sterling reputation.
No its structurally fine just doesnt accelerate well. I have a couple friends who have had their cars taken off the road for aftermarket electrical here in BC and I’m just worried about an inspection. I keep everything I drive safe as possible otherwise it would be gone already.
I was getting my fluids checked out and a coolant flush. I watched them do it and they took their time and were very transparent about the whole process so I felt good about it. What kind of issues can Midas give me?
Chains like Midas and Pep Boys don’t pay especially well and tend to have young, inexperienced mechanics. This is where they learn their trade before moving to a higher paying position elsewhere. Their diagnoses are not what they would be with more experience and they might end up throwing parts at the car. Not all shops are that way. My car wouldn’t start on the other side of town and my insurer had it towed to a Pep Boys. They correctly diagnosed the problem and fixed it.
Ive recently had electrical troubles with it. I grew up a believer so I aint going to hell for dropping this POS on someone else. It’s getting driven into the ground and then scrapped or parted.
Update for anyone who cares. Replacing all the fluids over and over, getting a new starter and my mechanic messing with my throttle has completely revived the truck for now. Drives nice and strong. Transmission is still crap but the burning smell I originally complained about dissapeared since i realized I had a coolant leak and just started keeping coolant on me. Thanks everybody for the help.
