Leaky Radiator Help???

Took the TJ to pickup the kids from school a short drive and then parked it in the garage. Went back out an hour later to a puddle of water/coolant under the jeep and the undercarriage all wet. ( I did shut the engine off while it was rolling in).

Crawled underneath with no obvious signs of dripping. The bottom portion of the radiator appears wet though. Coolant level is slightly below full, fluid comes out of the radiator cap when I try to take it off(even when cool). No problems with overheating. Drove the same pattern again and his time no leaking???


Could I have a leaky radiator that is just plugging itself back up. Everyone once in a while I get a coolant smell in my garage after driving it. Not very mechanically inclined but learning to wrench as I go.


Also is the picture below something to worry about or could someone explain what is/was leaking?

The best way to find a coolant system leak is with a pressure tester. Many parts stores have them in their loaner tool inventory.

Intermittent leaking, especially following a drive, is typical of a failing water pump shaft seal.

After additional research it probably is the water pump. I'm gonna try to replace it myself. Do you guys recommend Mopar or a cheaper aftermarket(if so which one)?


Thanks.

Don't bother wasting lots of time choosing a water pump. Aftermarket is Ok for a water pump, but do not get the parts store cheapest option which is usually a really dicey rebuild. Get a new one. Any parts store should have it in stock.

Aftermarket store-brand water pumps are prone to failing prematurely, I won't touch them. I'll run store brand floor mats, seat covers, or grab handles but for critical parts like water pumps, starters, sensors, etc. I'll run nothing but Mopar.

Don't let the so-called "lifetime warranty" given with aftermarket store brand parts fool you into believing it means they have good quality. It doesn't... it just means they'll give you a replacement when it fails again.

About 10 years ago, I was in a bind and had to buy a water pump on Sunday. Got one at Autozone. Since then, I have replaced it four times. The longest one lasted was 20k miles; 5k was the shortest. Even with the "lifetime warranty," I have spent more on antifreeze than I have saved on water pumps.

If you don't like replacing water pumps, round up a Mopar unit.

Agree on wearer pump oem as a real job to replace and an leave you stranded but for a starter after wife's Rubi key stuck in start and fried starter been real happy with zone lifetime

If ever fails can bump start and change out is a 3 minute job plus the 7 days a week available all you need is phone number no box or receipt BS is handy

So far three years on that autozone starter with no issues

Round up some Teflon tape as well. You will need it (or some pipe thread dope) for the heater hose nipple that screws into the water pump.
