Our JK Wrangler is getting some love today.

We’re fitting it out with some seriously useful gear, along with a range of off road parts like this tough E-locker, to make sure this Wrangler is properly equipped to go wherever it needs to, mainly Jeep Jamboree and back.

If you’re in the workshop, make sure you check out the range of products we have on display at the front of the shop.

Charlie’s getting stuck into the hose in the valley on this Grand Cherokee as part of our four hose package, before it heads north for some off roading in FNQ.

A blown hose in the valley is the last thing you want putting an end to your outback adventure. Better to tackle it in the workshop than get stranded on the tracks.

Haven't done yours but still want to get out there? Throw one of our hose packages in your kit, just in case. Better to have everything you need in one place than wait on a tow.

You may want to save our DIY video just in case you do need to do this yourself:

The factory towing eye that could end up flying through someone’s windscreen.

The towing eye in your ’s spare wheel well should NOT be mistaken for an offroad recovery point.

Using the screw in front towing eye to drag your Grand Cherokee out of a bog can turn a recovery effort into a flying metal projectile and put someone’s life at risk.

Watch this before you attempt a , there is a safer option from factory.

An EGR leak doesn’t automatically mean your needs a $3,000 EGR cooler.

We’ve seen these leaks quoted for complete EGR replacements when the problem was actually the seals underneath it.

The cooler itself can fail, but finding exactly where the coolant is escaping could save you a hefty bill.

In this video, we show you where these seals sit, what leaks and why checking the little things matters before replacing the expensive parts.

Cant find the green O rings? You can match them at your local bearing or engineering shop.

This well driven Supercharged Wrangler came in with a nasty whining noise from the rear end.

A quick inspection revealed very metallic diff oil and a magnet through the fill plug pulled out a broken tooth.

So, there was only one thing for it. Time for a rebuild.

Wont be long before this weapon of is back on the trails.

"Can I run just the headers and keep my factory exhaust?"

This is the number one question we get, and the answer is: technically yes, but it's not a bolt on system then. The pacemaker header fl**ge has 4 bolt holes, while your OEM system only has 2, a different bolt pattern and smaller diameter. So the stock cat back physically won't line up without some cutting, fabrication and welding. Add in the fact the factory cat is a lot longer than the pacemaker unit, and you're looking at a proper fab job. Our advice: just run the full pacemaker system, it's a genuine bolt on with zero fabrication needed, sounds amazing and is Australian made.

Dannie answers other frequent questions we get asked like do you need a tune? and are they easy to fit?

We've run this system ourselves on and and never had an issue, sound and finish are top notch. Full breakdown in the video.

We often get asked how we flush coolant in the Grand Cherokee's, especially after an oil cooler failure.

We use specialist equipment that evacuates the entire cooling system, removes trapped air, and then draws in fresh coolant under vacuum. That means:

No air pockets
Proper bleed and flush the first time
Full coolant replacement, not just a top up

For the DIY guy or girl at home, I know that’s probably not what you wanted to hear 😅

But fret not, you can make it work if you own a garden hose. Just take your time and please be mindful of the environment when disposing of the old coolant. It’s harmful and should never go down stormwater drains.

If you’d rather have it done properly the first time or not deal with the clean up and disposal, give us a ring on 9987 2818 and we can sort your out

This 3.6 Grand Cherokee came in with a misfire on cylinder 3.

During the diagnostic process we opted to do a visual inspection on the cylinder after removing the plugs.

Lo and behold, there’s the issue.

A blown head gasket means coolant has been making its way into the combustion chamber and effectively steam cleaning the top of the piston every time the engine runs.

And when we say clean, we mean clean. The piston crown is so spotless you can clearly read the serial number stamped into the piston, along with the QR code.

It’s a pretty impressive visual, but unfortunately it’s also a very clear sign that coolant is getting in where it definitely shouldn’t be.

If your develops a sweet coolant smell, unexplained coolant loss or an occasional misfire, don’t ignore it. If you have a misfire on a it is unlikely to be plugs and coils but usually something a little more sinister but still very fixable.

Two RAMs. Two cams. One very problem.

We’ve got two 5.7L HEMI RAMs in the workshop, both with the same P0308 cylinder 8 misfire, and both showing very similar camshaft and lifter damage.

One has travelled 102,000 km, the other 126,000 km, and in both cases the plugs and coils had already been moved around without the misfire following them.

Once we got further into them, the problem became clear. The camshaft lobes are starting to erode. With corresponding wear and pitting on the lifter rollers. On one engine, we can already see the beginnings of the same damage across multiple lobes.

It doesn’t take a completely destroyed camshaft to log a code either. Once the lobe wears just enough that the valve isn’t opening as far as it should, the ECU can detect the difference and start logging a misfire on the 's. We often see the SRT Jeeps come in with far worse lobe damage and misfire.

So if your 5.7 HEMI RAM has a persistent misfire, don’t immediately throw plugs and coils at it.

Move the plug and coil to another cylinder first. If the misfire stays on the same cylinder, it’s time to start looking deeper.

And if the heads and camshaft have to come out anyway, it’s the perfect opportunity to carry out an delete and replace the affected valvetrain components while we’re in there.

Watch the video to see exactly what this wear looks like before the camshaft is completely chewed out.

Jeep Grand Cherokee Coolant Leaks?

Coolant leaks are something we see constantly on , but where they leak from depends heavily on which engine you have.

On the 3.0L , there are quite a few potential culprits, including the valley hose pack, water pump, EGR cups and the infamous O ring on the octopus.

The 3.6L commonly develops leaks from the radiator, heater hoses and water pump.

And on the V8s, we regularly see leaking heater hoses, radiators and water pumps, particularly from the seal behind the water pump pulley.

the heater hose assemblies are different between the diesel, 3.6 and V8, so make sure you’re getting the correct part.

In this video Dannie runs through the common WK2 coolant leaks we see in the workshop and shows you exactly what to look for. We'll release an updated video with some shots of the leaks themselves soon.

If your Grand Cherokee is mysteriously losing coolant, this is one worth watching.
