87 c10 350 water pump?

[JonB9]

Ive got a 1/2 ton  c10 i love, but I've got a few issues and Im just looking for some advice... Unfortunately, money is an issues some I'm just trying to get the most out of any input. 

Ive got a water leak for sure.  My gauges are not hooked up so i have not idea if its overheating.  Thats next on the list to fix...
I bought it this way. 

 i brought it in last year and the mechanic said we checked the water pump and we don't believe thats causing the leak.  they replaced the hoses and made sure all was tight, but as soon as i drove up a hill  the leak started again. I had the tech but a gauge on it while they drove it back to me and no overheating at all...  It feels like its running hot to me though....

No cloudiness in the oil so i don't think its the head.  At this point I'm thinking just to replace the water pump and go from there.

Any other thoughts or ideas to try?   Thanks all

Do you see a leak, are you smelling coolant, or are you just having to add to the recovery tank?  Is coolant dripping from a hose or off the engine, or puddling on the ground?  Is coolant collecting on the passenger floorboard?  Is there any visible exhaust smoke - what color?  If money is tight, I wouldn't replace the water pump unless there is good reason.  You need to take some time to diagnose the problem rather than throwing parts at it.

Thank you-  The its dripping on the ground fairly steady.  It touch to see if its coming from a hose or the actual water pump.   I made sure all the hoses are tight etc, but originally the leak was coming form the hose...  No smoke etc, I guess i stet with a pressure test and go from there...
Thank you....

Can you follow the drip back up to its source?  When water pumps begin to leak they often have telltale green or red scale buildup on the underside of their snouts, around their weep holes, which maybe partially obstructed from view by the pulley.  Such leaks are most pronounced when the engine just begins to warm up, or as it cools down after being shut off.  If you pressurize the cooling system to about 20 PSI when it is cool or barely warm to the touch, you maybe able to spot the leak more easily.  Don't forget to look at the freeze plugs along the side and in the front of the block.  Other common leakage points are the four corners of the intake manifold at the coolant crossover ports.

im going to add something. if you noticed the leak when you parked on a hill i would look towards areas where fluid isnt normally but got there just due to the hill. since your rad should be full the engine should be completely full. the only thing that isnt under pressure and can change due to gravity is the overflow tank/hose

IM in the thick of it now..  thank you al very much. I'll let you know what I find...
