I'm losing antifreeze around the pet ****, but its tight and I can't see exactly where its leaking from. Any thoughts about what the problem is?

Best way and safe to check coolant leak. Use or you can rent one from
auto part store. "Radiator pump presure tester"
Let the engine cold down and hook it to radiator filler neck make sure it's good tight then pum untill you feel some presure, then it time to check for leak. You'll be able to see water comes out.

Water pump gasket most likely. or you did not ge the hose tight enough. Failing to get the pump gasket sealed is common.

Check you oil for signs of coolant contamination. If coolant is present in the oil, you may have a leaking head gasket or intake manifold gasket. If there is no sign of coolant in the oil, the antifreeze could be leaking past the intake gaskets and into the combustion chamber. It could also be a leak that only shows up when the engine is running, and you are losing the coolant as you drive. This kind of leak is very difficult to locate. You will have to look for signs of antifreeze around the upper and lower intake gasket area with a strong flashlight. Also check for signs of leakage at the upper and lower radiator hose connections and the drain valve at the bottom of the radiator. If you smell antifreeze inside the car, check the carpet for dampness caused by a heater core leak. Sounds like a lot of work, but these mystery leaks as I like to call them, can take repeated inspections before you finally locate them. I hope I have been of some help. Good luck and let me know what you find.

if cant find any spots on the ground an you're still losing anti-freeze, from my experience its always been the headgasket, if the headgasket isnt fully blown out your car will seem like its running fine an burn the antifreeze up during the combustion stroke of the engine, or it could be leaking onto the exhaust. check to see if theres any puddles of anti-freeze on top of the engine an check for leaks around the heads. if there is no puddles of leaks it could be your antifreeze is leaking into the engine an burning up during the combustion stroke

you will need to remove the radiator and upper and lower radiator hoses. get it out of the way, then unhook the a/c lines on each side of the condensor, then remove the retaining bolts that hold it to the body. it should come out then.you'll lose the coolant unless you drain the coolant[antifreeze] into a holding fan for reuse. remember if you have pets to store that antifreeze up and away from pets and children. you will also lose you a/c refrigerant. unless you have an a/c vacum pump.you'll lose it when you loosen the condensor lines.but if you're replacing the condensor i suppose you've lost it already. good luck! and thank you for choosing fixya.com

You state you checked the top hose, did you check the bottom hose as well? Also, there is the possibility it could be leaking at the water pump.

your heater core is definitley leaking and your blower is pushing the vapor into the cabin. It will only get worse. You can minimize the smell by not running your heater or defroster, but you wont prevent the coolant from leaking and potentially getting worse. Sorry to say, the core will need pulled and repaired or replaced. Sometimes stop leak additives will solve the problem if its not too severe. I have never been a fan of them, its only a band aid in my view. also if u got pets afoid leeting they smell the antifreeze very toxic can kill pets easily. hope this helps. rate above 4* cheers

hi i would try and re rout the hose, also you can buy the hose and fittings from most auto shops and if you having trouble fiding some, try a pet shop, the pump hose they use for aquariums is exactly the same and they do all sorts of fittings

There should be no anti-freeze under the valve covers, just valves, rockers, springs, and oil. If you are getting any antifreeze leaks at the valve cover then you have a cracked head. Since the engine has been pressure tested and has passed, my guess would be that the coolant reservoir is overfilled. Drain it down to the correct level and see if it does it again. If you are getting a strong sweet antifreeze odor when the car is running, you may be in need of a heat core. My PT Cruiser would leak sporadically, and after running a pressure test, it turned out that the 16 pound radiator cap I had on the car was losing pressure at around 8 pounds. so it would only lose antifreeze when it was really hot and/or I was running the AC.

the cover should be removable to be able to inspect the hose. if the hose is ok i would then check the water pump gasket and housing but be sure to check the hose clamps are tight first. hope this helps
