Default 1998 sportage antifreeze leak. HELP!

I have a 1998 Sportage four wheel drive. I've replace the timing belt and I just recently replaced the front drivers side axle needle bearing in the hub. They went out because the vacum host cracked and let water into the hub and dried out the needle bearings. I couldn't find a part number for a local parts house, the dealer had some in California. After measuring the bearing I discoverd they were a standard 1/2" x 1 1/8" X 1 3/8. I bought one at a bearing store and it seems to be working fine. A couple of day I discoverd a antifreeze leak under the car by the bell housing. It looks to be coming from the back of the engine in the bell houseing. My first thought are a freeze plug failure. I was hoping someone has a quicker fix to this issue other than pulling the engine. Any ideas? Someone give me an easy magical fix Please.

There is also a block-off plate on the back of the head. It's where the thermostat housing would be if the head were mounted on an engine in a front wheel drive car. Although, it's really not that easy to get to either. You may want to get a mirror and check everything at the back of the engine. There are some hoses back there for the heater core. Is the coolant leaking from inside the bell housing or out from around it?

Do you have a brand and part number for that bearing you got? I'm in need of one of those also.

Default Kia coolant leak

I believe it's coming from inside the bell housing. I'll take a closer look today when I get it in the garage. I'll be sure to check the hoses. Thanks for the advice.

As for the bearing it was just a simple 1/2" wide, ID of 1 1/8" and OD of 1 3/8. The dealer wanted $13.00 for the bearing but the wait was a killer. I paid $12.00 and had it that day. I believe the makers is Torrington and the part number is B-188. When I measured it the axle shaft was 1.18. The bearing ID is 1.25. I wasn't sure if the .07 was from wear or not but it seemed to work fine. I've only put 1K miles or so since the bearing change.

When I had taken a quick look at the leaking coolant the other day, It looked like coolant was leaking from the bell housing but I was crawling in from the passenger side. When I pulled it in to the garage I looked at it from the drivers side and I could see that the coolant was running down the oil pan to get to the bell housing. It turned out to be a bad O ring around a steel pipe going to what I would guess is a heater core tubing. I bought a O ring from the local parts store and it looks like it has stopped leaking. If not atleast I know where the problem came from.
