Car not leaking but is now?
Answers:
No make or model listed.
Pump area is that round the gasket or from the shaft,
If from the gasket it might just want a tweak on the securing nuts or bolts.
From the shaft it is the seal, take the pump back under warranty,
Head Gasket is an unlikely cause of this, unless it has been run short of water or suffered corrosion through lack of Antifreeze.
but start it without the cooling system cap on and look for air bubbles, big bubbles could be head, gasket, but new head gaskets seldom solve the problem, get a new well recon engine.
General rule dont prat around with head gaskets, change the engine.
Practical suggestions, does the temperature gauge read high, if so does the radiator fan work, common cause of overheating leading to leaks that., also Thermostat, does the radiator get hot, If the gauge reads high, and the rad is cold the thermostat is stuck change it.
I had a water weep on a Holiday in Scotland 600 miles from home etc and each day as soon as the temp gauge moved off its stop I pulled over and released the coolant cap released the pressure and put it on again, this stopped the problem, and it has not recurred on the flatter cooler roads of gloucestershire.
he may have just gotten the gasket in wrong, it could be that simple or it could have been a bad water pump just because it is new doesn't mean that their not subject to failure. Find someone with a pressure check system and have them pump the system up and check it for leaks.
Don`t emerse it in water then..!
What kind of car is it? Older Chevy's had water pumps with a back plate. I bought a new one, and had to take it off and seal the back bolts because some of them went into the internal pump area.
If you fear a head gasket leak, you can have your coolant tested to see if there are any fuel remnants in it. A radiator shop should also be able to check the pressure in the cooling system, which will also verify HG leaks.
He does a job, and then leaves the country. that sounds about right.
Could be a number of things from bad water pump to loose hose or bad gasket or gasket slipped when installed,take it in and have it pressure tested or maybe have a dye test which in my opinion is much more reliable for it will show exactly where the leak is.The dye will seep out and the mechanic can tell right away where the leak is.
you didnt say what kind of car that would help it may just be a loose lower hose clamp if its a v6 or 8 it could be the intake manifoldgasket the best thing would be to get it pressure tested the leaks always show up that way
if your friens used silicone to seal the pump it could be leaking from there as silicone is almost always garranteed to leak use "the right stuff" sold in many auto parts stores if installed corectly it wont leak
Yes, the gasket may be the problem, although sometimes what happens is that if you don't replace everything around the pump, that may lead to problems in the future. I suggest you check the pumo first because it might still be good, but you may have to replace the gasket. Also check your radiator and hoses because sometimes the leaks are som tiny that you can't even see them on the spot.
GOOD LUCK
Are you sure the water is coming from the pump and not the head gasket?? It sounds like the pump seal maybe leaking due to dodgy seal or incorrect fitting, it's unlikely for a pump to go so quick!! The head gasket goes due to overheating or age.Check your rad water for signs of oil and your oil filler cap for water (creamy gunge) If OK I would remove the pump and check it's sealing onto the block.
try tightening the hose clamps down around the pump, as for the head gasket. do you see white smoke when you start the car? some chevy's also have a water jacket running through the intake manifold and will also leak coolant down into the cylinders and cause this smoke.
either the gasket has pinched when fitted or the pump is duff.
when you have sorted it get the system pressure tested to make sure you have no more leaks.
head gasket
try a new gasket after all mechanics are only human
