Regarding Engine Coolant and Oil Filter

Two questions.

1. I looked at my engine coolant reservoir and its really low. I cant see any "lines" that say MAX or High or anything. My engine isn't overheating but I'm worried since its way at the bottom of the container. I've read 8 million different things online what do I need to fill this?

Some people say do not mix it 50/50 with water some say do, some say get HOAT some say don't what is the factory recommendation?

2. I got a microguard oil filter is this ok? Every brand I look up people say it sucks. Fram-Sucks MicroGuard-Sucks Wix - Sucks STP - Sucks. I don't know what the hell to listen to. I put in Mobile 1 Synthetic Extended Performance if it matters.

I use the regular Mopar oil filter that I get on Ebay for about $6 each. I buy them 10 at a time for $60.

I run the mobil 1 filters, Fram does suck, but everything else you should be fine with, just replace it everytime you change your oil. And I have no clue about the coolant, I've been wondering the same thing.

Coolant
If your Jeep is 2012 use Hoat, if it is 2013 use OAT meeting MS12106 which I could only get from Jeep dealer. I needed to top off the reservoir after I burped my 2013

As far as oil filters, Wix are great and they make the filters for many auto companies.

I've noticed my 2013 JKU had low coolant recently as well. Bought in September 2012 and just eclipsed 8,000 miles this weekend. After I filled it up a bit, it seems ok. Most of my driving has been highway in very windy conditions.

This. And you cannot mix any other coolant with it! I got mine back after first service and dealer had not topped off the washer fluid or coolant. I was surprised to see only a spoon full of coolant in reservoir with only 4500 miles. I cannot find fill mark either. You may be shocked when you purchase a bottle. I just paid the local dealer $62 with tax for a gallon (or liter) this morning. Hey even the parts guy joined the pity party.

Can I pour it in with the coolant that is in it already?

You can just use distilled water to top off. You're ok with distilled water 60/40 ratio, even in a cold climate. I wouldn't go more than 60/40, even in a hot climate, because you still need the anti-corrosion agents regardless of your climate.

Trust me, its not a problem, and this is coming from a paranoid person that once sucked excess oil out of a tube to get the level perfect! lol. Seriously though.

Trust your 2013 Owner's Manual. Two quotes below. Applies to 2013 only. I used a 50/50 mixture with distilled water(the recommended water).


"CAUTION!

Mixing of engine coolant (antifreeze) other than
specified Organic Additive Technology (OAT) engine
coolant (antifreeze), may result in engine
damage and may decrease corrosion protection.
Organic Additive Technology (OAT) engine coolant
is different and should not be mixed with
Hybrid Organic Additive Technology (HOAT) engine
coolant (antifreeze). If a non-OAT engine
coolant (antifreeze) is introduced into the cooling
system in an emergency, it should be replaced with
the specified engine coolant (antifreeze) as soon as
possible." Page 578

"Component Fluid, Lubricant, or Genuine Part
Engine Coolant MOPAR Antifreeze/Coolant 10 Year/150,000 Mile Formula OAT (Organic
Additive Technology) or equivalent meeting the requirements of Chrysler
Material Standard MS-12106." page 611

2013s use OAT coolant which is purple & is a 10yr/150kmile. 2012 & down use the HOAT which is reddish/orange in color & is a 5yr/100kmile. And any of those oil filters will work jhust fine as long as you regularly maintain & change your oil accordingly.

We ONLY use Wix filters, and top off your coolant bottle with 50/50 coolant

Does anyone have a recommended coolant bottle I should buy? I'm not seeing HOAT on anything at Walmart and a lot of the ones I see are already premixed.

What happens sometimes is that the factory doesn't get all of the air purged out of your cooling system. Most of them will purge themselves and then draw the coolant from your recovery bottle back into the radiator as it cools down, that's probably why you are low in your bottle.
If 2012 you must use Hoat, 2013 Oat. Just go into your Jeep Dealer and purchase the correct coolant. When you add you want a 50/50 mixture of antifreeze and distiller water. Do not add tap water.
If you decide just to top it off with water, use only distilled! If you do this your bottle will not have any freeze protection until you drive it for a while so that the current coolant will mix with it.

As for the oil filter, your Jeep Dealer will sell you the correct Mopar filter for $5.70. I just purchased two of them at that price from my Dealer.
As for oil use what your manual recommends.

I think this is good advice, given the confusion.

It won't say HOAT on it I am sure, the Mopar kind doesn't say HOAT on it. It will say 5yr/100k mile Embittered on it. Heres a pic of the Mopar coolant for you. If you lived near me I would give ya some, I got about 12 gallons of it under my table right now. And I know people say mixing this 5yr red coolant with the standard 3yr green coolant will cause it to gum up & clog. I have yet to ever see that happen. I had them mixed in my CJ w/o issue. What we have been told is that if you mix them is that you lose the extended life properties of the Embittered coolant. It means you only have a 3yr coolant instead of a 5yr. Kinda like mixing synthetic oil & conventional oil, you only get the protection of the weakest ingredient basically.

I assume you have a 2007-2012. If so then this is the stuff: Valvoline.com > Products > Zerex > Antifreeze Zerex > Zerex G-05® Antifreeze / Coolant The stock fluid is orangish and the Zerex stuff is yellowish, but it is HOAT and is DaimlerChrysler MS 9769 Approved. As legitposter already indicated you can just top it off with distilled water.

Do any of the major parts stores carry it?

There is a "Max" and "Min" line on your expansion tank facing the drivers side fender. Not easy to see sometimes but it's there. From the factory, it's filled anywhere from 1-3inches above the "Min" line "cold". If that's where it is it's normal. With a hot engine it should be between both lines not to exceed the "Max" line. If you fill it to max when cold it will will most likely push out when the engine gets hot. I would use either Wix or Mopar oil filters.
