I have a 99 explorer with the 4.0, I was doing a cooling system flush a while back and was out of town when a freeze came to our area, luckily the block didn't crack but I noticed it was missing a freeze plug in the passenger side, I put one back and added some water but found a leak in the water pump wich I'm fine as I new I needed to replace it as it was getting noisy, but I know I have another leak and can't figure out where is coming from. I see a constant flow of water in the back of the engine, transmission area if I look under the car. If I turn on the engine I see 2 water sprays from the back of the engine in the driver's side. Where that water could be coming from? Thanks in advance.
