Default Water pump leaking and A/C problem?

Hey guys

1st, My coolant light came on a month ago and i finally decide to take a look at what was wrong i looked underneath my car and i saw a little coolant dripping down off the water pump. It looked like it was coming out of the weap hole on the bottom. My question is do I need a new pump or do i just need a new gasket or something?

next

I have been trying to fix my a/c for a while now, no matter what i do I cant get it to take a charge, it wont take in the freon. the Compressror does not come on. I replaced it a couple of months ago when the old one locked up. Is there a temprature switch i need to bypass or something? The pressure switch should be good because i pulled a vaccum on it and saw there was pressre with my gauges. What do I do?

Thanks,
Adam

#1 When you see coolant coming out the weep hole on any vehicle's water pump, it's replacement time. You can't fix them at home.

#2 You'll need to jump your A/C compressor directly to the battery to get the clutch engaged. This assumes that it's only a low charge problem and not something else preventing it from coming on. A pair of alligator clips and a dimes worth of wire is all you need.

checking it a month after the light came on is neglect and will cost you dearly if not fix'd now...i'll give you a grand for it how it sits...other wise fix it before a bad pump becomes an opti or a head gasket

for the A/C you can look at the compressor relay in the drivers side fender well fuse box. A/C was out on my car when I got it. Wouldn't kick on the compressor so I uncapped and manually actuated the relay. Compressor came on, no cold air (didn't have a set of gauges to see if it would hold vacuum, so I stopped there until I had the tools to check that and do a charge/ leak test with dye). If you're sure there's refrigerant in the system, you may just need a relay.

You don't need top jump it off of the compressor directly as you can make a jumper wire about 3 inches long and just jump it off of the relay. Pull the relay in the fuse box and put a jumper wire in there to kick on the compressor manually and check the pressure in the system once its running before you dump 134A into it. As said you could just have a bad relay, esp if the compressor is new.
