2017 Ford Explorer Sport Trac Engine Replacement
2017 Ford Explorer Sport Trac Engine Replacement – So we’re going to try and run a castthat we’ve done a few times on the Ford Explorer Sport Trac engine replacement.
So this vehicle light wason, very minimal amount of power, the vehicle would barely run to be honest it was surprisingthey could even be driven to our shop.
So we proceeded using diagnosis, it was apretty complicated diagnostic, there’s a number of trouble codes without getting tootechnical, there’s a number of trouble codes stored in the vehicle computer for a varietyof misfires on the right cylinder, in the right engine bank there was also a cam phasercode for the left engine bank which seemed a little odd because problems all seemed tobe on the right.
It kind of made sense there’d be a camshaftlike a valve timing problem could be the issue so we proceeded to do some diagnostic, itwas a very long arduous process and in the end we found that the engine needed to bereplaced basically due to the fact that the oil pressure in the engine was too low toadequately operate the valve timing phasers and eventually the timing chain would startrattling and the valve timing would go out and that was part of our a lot of our misfireissue.
We did, we ended up replacing theengine so whenever an engine needs to be replaced we look at options, and it’s always an expensivejob.
For used engines, good used engine which aresometimes a good idea, in the end we settled on a rebuilt engine from, directly from Fordwas a factory rebuilt engine bolted on, complete valve covers, all new sensors, reallydeluxe package and quite a treat.
A lot times you get a rebuilt engine, it doesn’tcome with the oil pan, you have to change a whole bunch of things over and this onewas very complete, so it worked really well.
I’ve got a few photos to share and justa couple of things here, so basically here is our view of the top of the engine, it’sa 4.6 litre, it’s a lot of plastic which is typical for modern engines.
As far as diagnostics and I mentioned thatit was a bit of a tricky diagnosis on this vehicle, some of the tools that we use, oneof lab scope and so this is a lab scope pattern, there’s a yellow and a green trace you cansee on the scope and this is, this shows the cam timing of the two different cam phasersand it’s something we use to figure out what’s going on with the engine, whethervalve timing’s out.
In this particular photo everything’s, thispicture everything’s good at the moment but it changed as time went by and we couldverify a lot of things but it’s a time consuming process but it tells us a lot of good accurateinformation and finally there’s our Ford engine.
This is the new engine sitting waiting tobe put in, actually the other thing that’s really neat about it is actually it comesfilled with oil and a new oil filter as well which is pretty awesome so that’s the newengine right out of the crate and yeah, so there’s our photos, so I’ll go back tous.
Bad maintenance, yeah this enginecame in was way over due for an oil change. The oil was hideous and it did have 200,000kilometers oil changes, done at the right time, 200,000 kilometers is really nothingso I’d say it’s bad maintenance absolutely was the cause.
So once you put the new motor in howdid everything run? Bernie: Well it ran very smoothly and we gotit on a road test in the parking lot and it still but what else happened becausethe owner had driven it for so long with the engine misfiring it actually melted the catalyticconverters and caused.
Converters and thenit was fine, so the lesson here is when your check engine light is on, it’s blinkingdo not run the engine for very long, drive it like, drive it gently as possible and getit fixed.
When the check engine light comes on and it’sjust on solid, it’s not often a big deal but when it’s blinking that’s a seriousissue and you know that catalytic converter job on most vehicles is another 1,300 buckson top of the engine so and that’s buying aftermarket conversion, if you went to Forddealer it would be twice the price, so maintain your car that’s what we always say here.
