Radiators Leaking Time to Replace It / Jeep Wrangler JK / How to 

🍻

Its not the valve thats the issue. Its the fact that it's streaming right onto his front steering linkage and spreading out everywhere.

@@bobaganoosh88 sure - but they valve is made for a hose to be connected, avoiding that issue.

🤘

It was already done.

2008, add coolant last.

It shouldn't be, coolant for 2007 - 2011 jk is hoat technology which mopar is like a red, maybe you should ask.

Prestone is green and works with any system. The Mopar coolant is problematic and causes tons of issues with the heater.

Rotates in place.

Yes CSF radiator am looking at that as well I do need a radiator with built in trans cooler since mine is has a auto trans

If nothings coming out then your radiator is probably empty or you haven't removed the drain plug.

The radiator is probably leaking, a pin hole can be hard to find and make a big mess.

The issues happen at the seam between the metal and plastic. The coolant breaks down in time and the metal will start to corrode.

Have fun!

Use your original cap.

I'm in the middle of a headgasket on this old jeep, should have the video out this weekend. The first sign was the reservoir filling ......

I've read this same story a lot of times in newsgroups - folks going away from the MOPAR replacement part and upgrading to aluminum third party radiators, only to have them fail in the first year. When possible, I try to avoid MOPAR parts, but there are a couple of parts on a Jeep where MOPAR is the best option - and it seems like the radiator is one of them. The radiators on the Wranglers take a BEATING due to the way the air flows through the grill. Because of the high heat design of the 3.6L Pentastar (which is designed to operate at 221 degrees F), we really can't change out the grille to something that offers more protection from debris, as ANY limit to airflow is known to cause these engines to overheat (even the mesh that some people install can cause overheating). So, I've just budgeted replacing the radiator every 4 years (how long my first one lasted) for $350. Worth noting, though, that the MOPAR radiator has been upgraded over the years. The part # now is NOT the same part # that was used off the factory line on my 2016 JKU.

This is why Jeep added stop leak in all the OEM coolant at the factory. The downside is that the stop leak kills heater cores.

@@oscarwinner2034 damn, is there anyway to mitigate heater core problems?

@@sdericmonty Replace it. It's easy. Rock Auto has replacements for around $75. Takes about an hour to get in and swap it. I did all the flushes and all like an idiot before I just replaced it. Was kicking myself for not just doing it from the start and being done with it. The original core - once drained - was caked up solid inside. Hard bonded black material. The fins are narrow inside. So most of the core was clogged solid. It isn't sand. Sand don't bond like that and sand is very fluid in water.

@@oscarwinner2034 damn that’s crazy! Thanks for the info!!

No more than 4 hours,, that's with using a camera along the way.

Good time to fix it

Thank the minimum wage increase. Sorry🤷🏻‍♂️

Rock auto has them for less.

It's over $500 now.

Everybody wants to make $20+ per hour, not realizing that it causes everything you buy to go up dramatically…..duh

🤙lol

Ah, honestly, you need to do alittle more research. The only place you going to have you tesla serviced is tesla. Their going to charge you what they want. Lol. Dont think they don't have problems. Lol.

Generally, the engineers design these things to work, and work efficiently. It's when the bean-counters get involved that you get cheap build quality.

Turns out they have more problems than just a regular truck hahaha 😂
