Question about 2002 Chevrolet Silverado

1 Answer

Keeps needing antifreeze and no leaks

My pickup continually needs anti freeze. It does not leak anything on the ground while parked. When the engine is running if I rev the engine and look at the tail pipe there is no smoke or anything. When the engine almost returns to the idel mode a little white smoke come out of the pipe. I thin the intake manifold gaskets are leaking. Can a dumb guy like me replace these gaskets at home in my garage?

You didnt state year make or model of it. But if you take pictures and mark everything you should be fine.when taking things apart be aware of bolt lengths.take cardboard and trace the part pop a screwdriver thrue the bolt holesand put the bolts thrue cardboard cutout.

There is a water port there. So it is possible. If you try cleaning the area as good as possible and then start the truck and let it run and watch that area. More then likely it is the intake gasket.

SOURCE: Anti-freeze leaking from either the freeze plug or

Without knowing what year or engine size is, I/m just guessing??????? But the 3.1L engines are FAMOUS for intake maniflod gaskets leaking. Look where the intake bolts to the heads. A freeze plug is in the block. Freeze plugs dont leak unless you have been running pure water or weak/cheap anti-freeze. They will rust out from behind and its BIG BUCKS to replace them all.

My 04 Tahoe is blowing out white smoke when I crank it. I seem to be using a lot of oil and antifreeze but I don't see a leak on the ground. Will it harm the engine if I continue to drive?

yes you can cause mechanical damage. have the motor checked out. the reason you don`t see anything on the ground is your burning oil and water, not to mention the excessive emissions that you can be fine for plus your doing damage to the catalytic converter.

Anti freeze on top of valve cover

A flashing check engine light is a very bad thing. You are not supposed to drive it when that light flashes because engine damage will occur. You may have a bad head gasket and now it is severe.

My 01 Blazer is completely will not start. There is no turn over sound; Absolutely no sounds at all.

You could have serious trouble with the engine losing that much anti-freeze. If it is not leaking out somewhere onto the ground, it may be from a bad head gasket that is letting coolant burn in the cylinders (you would see white smoke out the exhaust), or it may let the coolant get mixed into the oil in the lower engine's crankcase.
Pull the oil dipstick and look at it. If the level is way high, or if the oil color is milky brown looking, then you have water (anti-freeze) in the oil-a bad head gasket, and a big expense to fix it. That would explain the rattling: water in the oil stops the oil from lubricating properly, and the engine bearings and other moving parts inside the engine can be damaged. If this is the case, and the reason for the rattling, then the engine is shot and needs a total overhaul, or you need a different engine.
If the coolant was leaking outside, post back. Has the engine ever overheated from low coolant? The rattling is worrisome-have a mechanic listen to it if you get it started. If it won't crank over, have someone see if the engine can be turned by hand-if it still turns freely (not siezed up), then the starting circuit needs to be checked for why the starter won't work. Good luck. Check the oil first thing.

I have a 1997 Chevy lumina anti freeze is leaking from picture what might it be

It might be an antifreeze leak. Does the engine running hot? Does it stink? Are there drip marks on the ground below the engine? Then it's probably a leak.

Hope this helps.

I have water - I think - leaking from just behind the belts on the main engine (not part of the belt pulley system). When I rub my finger in the liquid, there seems to be no oil in it. There does look to...

This sounds like a water pump leaking. Get a mirror and see if you can see the place where the leak is coming from. On the water pump is a small hole, this hole is called a "weep hole". it is there to warn that the water pump is getting worn and may fail soon. Anti-freeze, once it leaks on to the engine and gets warm enough to dehydrate then gets some road dirt stuck to it, it does looks a lot like oil and feels a lot like oil. I think your are looking at a coolant leak coming from your water pump. A shop can pressure test the coolant system and find out if it is the water pump or a head gasket. Hope this helps FixYa up.

Tempature light on H and engine runs HOT and leaking Anti-Freeze underneath. oil light comes on, oil level is full

fix anti freeze leak, the oil sending unit is probably gotten wet and sending a ground reading which causes a false reading or light.

My 07 impala is losing anti freeze but nobody can find a leak anywhere how can i solve this problem

if cant find any spots on the ground an you're still losing anti-freeze, from my experience its always been the headgasket, if the headgasket isnt fully blown out your car will seem like its running fine an burn the antifreeze up during the combustion stroke of the engine, or it could be leaking onto the exhaust. check to see if theres any puddles of anti-freeze on top of the engine an check for leaks around the heads. if there is no puddles of leaks it could be your antifreeze is leaking into the engine an burning up during the combustion stroke

I have had my radiator replaced twice because my car started running hot. Now if my car idles too long the temp will go to hot. I have added more anti-freeze to the radiator but I never see anything...

possibly a blown head gasket. Take off the radiator cap and run the engine--are there any bubbles coming up in the coolant? Check the exhaust pipe--is it steamy or does it smell like anti-freeze?
