I have replaced 2003 silverado water pumpthree times and it is still leaking? is this year 5.3 size moter knowen for internal leaking and if so how do I stop it?
it could be leaking from some were above and its driping on the pan causing it to look like its leaking from the pan or if you over tourk the bolts it will warp the pan causing it to leak
i have a 97 neon i took it to a shop they replaced the valve cover gasket but its still leaking oil in the plugs what has to be done
You've got either a leaking intake gasket or a leaking head gasket. It's a serious problem which needs to be repaired.
Did you check the thermostat to make sure it is working? If it is and you have enough coolant, you might want to check for head gasket issue. You can rent a tester at Autozone. HTH
Make sure it is the pan gasket leaking and not something higher up getting oil on the pan. Check that the pan is not warped using a straight edge. If it is straight clean both mating surfaces and tighten fasteners to specified torque. Do not over tighten this can cause the pan to warp and leak.
Find another mechanic.
Remember that there is no such thing as a "normal" leak. Sometimes water condensation will build-up on the AC pipes and drip-off, but there's not a "leak" involved. Get your manifold gasket replaced ASAP. It costs money but it's worth it. I've had mine replaced about 5 years ago and it still runs great.
blown head gasket is the usual reason for oil in coolant or radiator. sad part is if you have already replaced intake gasket, u wasted your money as you will have to replace again when you fix head gasket
Probably a bent valve cover from overtightening Replace or try to straighten then tighten to 10 inch lbs. only
The intake manifold are very bad about corroding a hole in them which means that you will have to replace it
Did you replace /check the seats also?
Not to my knowledge...but there is a gasket around the timing cover that will leak antifreez if it goes bad. It is a pain to replace, but it can be done. If you've replaced the water pump and it's still leaking (as was my case), then go one step further and replace the gasket around the timing cover. ***caution*** use a repair manual before attempting this!!! There are ***a lot *** of bolts to undo and some require sealant on them when they are replaced. The manual will tell you which ones to put sealant on. steve phx az
Maybe it's not the radiator. Maybe it is one of the radiator hoses that is leaking. Or possibly the radiator cap or a level sensor.
Coolant lines? Shift linkage? could also be the rear or front seals leaking
If a lower radiator hose was replaced on a 1999 Dodge Grand Caravan, but it is still leaking fluid, it could be that there is a hole in the radiator. It could also mean that there is damage to the overflow reservoir or its hoses.
Where is it leaking from? Could be front or rear seal or coolant lines Did you change gasket when you changed fluid?
Bad installation. Try some permatex "gasket maker" and re-do it. dave
it could possibly have either a blown head gasket or intake manifold gaskets leaking
Either the water pump impeller is loose on it's shaft, or you have a leaking head gasket.
They fixed the replaced the raditor and it still leaks in front of the vehicle.
if you had it heat high enough it very likely worped your heads and or damaged the head gasket
Were the spark plugs oil fouled? If so it can be a valve cover gasket, oil would be leaking into your spark plugs.
leaking anti freezei also have a 1997 Avalon xls it has 191,400 miles on it,i also had radiator problems,had a hose blow out replaced that then radiator blew replaced radiator while ill replaced the bottom hose at that time also ,then i noticed it kept leaking from the hose ends,so i tightend the hell out of them then i reliazed the cap was bad replaced that i finaly came to relaize that there was to much pressure so drained a little fluid from it still seems to leak a little because i can smell it but i don't know where its leaking from and its not getting into the oil,somebody possibly said to much pressure and it could be the head gasket,but since draining it it seems to be ok
If the pan is leaking at the mounting surface on the engine, then try tightening the pan bolts to 6 ft/lb of torque. If that does not stop the leak you will need to remove the oil pan and replace the gasket. If it is leaking at the drain plug, replace the gasket with a fiber gasket and toss the metal one. If it still leaks at the drain plug you will have to have the pan removed and welded and new threads cut as the threads are stripped or the pan is distorted.
