![]() One common problem in these engines is the valve seats fall out which is, which involves some major engine disassembly and major expense so you know, overall they’re not the most reliable vehicles out there, there’s a lot of them and if you’re asking do we want, which is better the diesel or the gas, I couldn’t really say which is better but because the diesels are, the diesels have their engine problems and they cost a lot to fix so if you’re wanting a vehicle that doesn’t have any problems, this isn’t the vehicle to buy but they are nice little niche vehicle you know, their size and being all wheel drive. Mark: Or into the, just into their competitors even.īernie: Yeah, yeah I’d say these vehicles do have their issues, the engines have problems you know, we’ve seen timing chain issues with them, we’ve also seen one common problem with this engine and it’s a 3.7 liter V6 Chrysler, also uses a 4.7 liter which is basically the same kind of engine but it has two extra cylinders, it’s a V8 and not a V6. ![]() Mark: So how reliable would you say these gas powered Liberties are in comparison?īernie: Comparison to the diesel is what you’re saying? Mark: So besides leaking coolant and you know potentially causing overheating problems, what other problems did this cause?īernie: Well this was actually causing the engine a slight misfire, the sparkplugs in this vehicle were quite old and we replaced them but I mean, had it started leaking a lot worse the engine would have developed, definitely developed severe misfire and with coolant seeping into wiring connectors, it can cause damage as well so I think, you know this leak may have been going on for a little while but we caught it at a good time to fix it, so the repair, basically new spark plugs just based on age, cleaning up all the leaked coolant and the ignition coils and replacing the coolant bottle and we flushed the coolant system with fresh antifreeze as well. but these ones are covered especially this one in the antifreeze residue and its run right down into the spark plug tube and caused, created an engine misfire. We have one more photo here, this is, these are the spark plug, sorry these are ignition coils taken on that cylinder bank so you can see that these coils are, this one’s o.k. Now around here we have fuel injectors, we have ignition coils, that’s kind of the critical piece, the ignition coils sit in this area here and coolant is dripping down on top of the ignition coils running down into the spark plug wells. I’m just going to work my way through these shares here, so this is the result of that coolant leak and if you look down, this is the top of, this is the right cylinder bank of the engine, and coolant bottle sits on top, now all that reddish coloured stuff that’s dried up anti-freeze, Chryslers anti-freeze from the factories are reddish coloured so that, it ends up showing like this. ![]() Now where this bottle is located on the engine is kind of the critical part. There’s a very small diameter hose, it’s basically an air bleed supposed to keep air out of the system so it circulates coolant and where the bottom arrow here, is where this piece here is supposed to attach into the coolant bottle so what’s happened is this, this has actually created a coolant, a small coolant leak that spews coolant out. This is where you fill the coolant, now the red arrows are pointing to what’s broken on this piece. So this is the coolant overflow bottle, it’s located on the right hand side of the engine compartment and it’s basically an expansion tank for the cooling system, this is where the radiator cap, it’s, it’s out of the frame off to your right over here but the radiator cap sits on top. I’ll just show some photos here, this is our actual coolant leak. Mark: So was there a lot of coolant leaking?īernie: There wasn’t a lot and the interesting thing is the way the coolant was leaking, you know the way because of where the coolant was leaking, it wasn’t a large leak and could never amount to a large leak but where it was leaking was what’s really the most important thing. So this is a gas engine which is a bit different than, talked a lot about their diesel vehicles, this is gas, what was going on with this vehicle?īernie: Well, this vehicle came to us for a maintenance service and an inspection so we had a look at the vehicle and found a few things, one of them was a coolant leak on top of the engine which was not a huge leak but definitely something potentially serious which is why we’re talking about that on this hangout. Mark: So we’re going to talk about jeeps, we’re back into the land of jeep, a Jeep Liberty 3.7 liter.
