2002 Chevy Tahoe - started leaking anti-freeze after took to a fast lube shop. Leaking a little and sometimes a lot when the truck is in the driveway. Anti-freeze appears to be originating from above the oil filter leaking down over the skid plate. Any suggestions. Not over heating and still holding pressure when take the reservoir cap off.

    i am not at the shop so i cant look at the picture of the oil filter housing at the moment but most of the oil filter housings are also asking as a oil cooler coolent flowes through it to keep it cool. there are two hoses going through it if they are damaged coolent can leack out of there. but the question is where its leaking from??? inspeck the engine its not always the mechanic lol they are there to fix unless you are taking to some cheap *** place. this truck have alot of room to go under and inspect if the leack is by the radiator cluch fan shaft its the water pump. if its near the bumper its the radiator if its in the back of the motor that can be the heater hose if its on the sides can be the hoses

SOURCE: Anti-freeze leak

If it's leaking at the top of the engine down. Look at the top of the engine at the front and you'll see a bleeder valve on top a black housing. These housings like to come apart at the glued seams. If it's leaking at the lower part of the engine towards the front, it could be your water pump leaking. Check your oil and if you see the color of the oil looking like chocolate milk, your water pump needs replaced, the oil will need changing as well. Do a coolant system pressure test and see if your hoses somewhere are leaking. Also check for your surge tank leaking. This is the tank that you put coolant into.

SOURCE: 2007 Escape oil pressure issue/oil pump

one thing to keep in mind that even though the vehicle is new you can still have major engine issues, because of the bearing material may have been bad at production.taking this in account any part on a vehicle can fail prematurely either because of poor insatllation or improper manufacturing. As far as oil filters are concerned bthe odds of mechanic installing the wrong filter are slim to none.the oil pressure sending unit only senses that here is oil flowing through it. it doesn't set the light off unless there is absolutely no pressure at all the only way to see the pressure is to have a gauge. oil prssure should be abot 45 psi at 2000 rpms. the only way a filter would effect oil pressure is if it was completely clogged. It would take a great deal of coolant in the oil to ruin a set of bearings and before that happens your vehicle would not run very well and you would notice a great amount of white smoke out the exaust. this would indicated either a blown head gasket.cracked head or a cracked block. you never mentioned what they found in the anaylasis of the oil. I presume that your vehicle is still under warrenty on the powertrain. I would suggest that you have the dealership check your oil pump out. every vehicle will have a small amount of metalic residue in the oil. large shavings and chunks of metal would be a worry. please rate this thanks.

SOURCE: 2002 chryler sebring is leaking anti freeze

It depends on where the leak is coming from. If the water pump is leaking, it has a hole on the bottom of it. You will see a trail of dried anti freeze coming from the bottom of it, indicating a bad water pump. It's best to dry everything off, crank it up and let it come to operating temp and check for where the leak is coming from. It may just be an old hose or loose clamp.

I have a 98 chevy tahoe (5.7l) i have changed plugs, wires, cap, rottor, oil, and mass air flow sensor. but the computer reads every thing is working. except misfires in cilnder 5&7. HELP!!!!!!!!!!...

do a compression check on those 2 cylinders to rule out head gasket, check the new plugs you installed to see if they got fouled out, it is possible some anti-freeze may be leaking into those cylinders from the intake gasket.
1998 uses dex cool anti-freeze and it is known to eat away and corrode the gaskets.
the only good way to use dex cool is to mix precisely 50/50 and use distilled water.
switching to the green can cause water pump damage since they are designed for the lubricant in the dex cool.i mention the anti-freeze because a lot of people will change the gaskets and run the green only to have a failing water pump not long after, if you decide to switch make sure you replace the pump.

if you put a little of the fluid that has leaked on your finger tip and taste it,if it tastes sweet then its engine coolant(anti-freeze),if its bitter tasting then its brake fluid,if its dark in color(brown/black)it could be motor oil,if its red in color it could be transmission fluid.once you know what type of leak it is then you can check for were its coming from.

Steam from antifreeze coming from right side of engin

I would check the hoses in that area. It maybe the the water pump bearing shaft seal. There is usually a small drain hole towards the bottom of the pump, that will leak anti-freeze when the seal goes bad. With an inspection mirror, you may be able to see if anti-freeze is leaking from the pump.
