I have a 91 Jimmy, I have a coolant leak and can't

I have a 91 Jimmy, I have a coolant leak and can't figure out where it's coming from. I replaced the water pump two days ago and it still leaked, so yesterday I replaced the radiator to water pump hose, and it's still leaking not from the radiator and not from the water pump. And it's not from the motor because its under the radiator to water pump hose. I tightened the hose clamps real well, can you help me?

I think the overflow tube is leaking and it is flowing in a path to the hose

SOURCE: coolant leaking

Hello Kasalama :

Is it possible to wash off the engine while protecting the distribuutor and other electronics so we can start with a clean and dry engine ? . * Make sure that your radiator is full and that the Radiator/ Coolant overflow reservoir is at the proper level . * I would put a large piece of cardboard on the floor and along with a bright flash light or shop light use it to guide you where the leak s coming from .

If that is not helpful , I would perform a pressure check on the cooling system . The pressure check can be performed as a diagnostic tool . Put the truck in park and apply the parking brake . Attach the pressure diapham and Start the engine . You will have to manually pump it to a specified pressure as indicated on the gauge/ manometer .

The pressure diaphram usally attaches where the " radiator cap " is . Applying pressure can show leaking hoses, pipes and leaks in the radiator or fittings .

Be mindful that you can also have a leaking Intake manifold Gasket .

I hope that this info has been of help to you .

Changed spark plugs now runs rough and has thick white exhaust

Changing the plugs probably had nothing to do with it.
White smoke is usually a sign the engine is burning coolant or trans fluid. You might want to check those fluid levels.
If the coolant is low, you may have a leaking head gasket or intake gasket.

Water leaking under my2001 gmc jimmy

Could be a hose, could be a soft plug, could be a water pump, could be an intake gasket. Need a little more information, couldn't the people who found the leak tell what was leaking? You will probably have to get under it and look around and see where the water is coming from. Please rate my answer so I am rewarded points for it.

My 96 Jimmy leaks coolant from below, sometimes worse than other times. What's the problem do you think? How expensive? Thanks! Gordon

Look at the water pump. These will usually leak more when the engine is cold, such as when it sits over night, and can sometimes stop leaking all together when the engine is warm. There is a breather hole in the pump, right below the fan blade, and that's usually where you'll find the leak. See if the lower hose has a coolant stain on the bottom of it. follow it up to the water pump and you should probaly see the breather hole leaking.

My 1998 jimmy has always leaked antifreeze but the last month it has got bad to were i have to fill it up everyday

You need to get or rent a coolant system tester and identify where it is leaking from. They are very simple to use. You just remove your radiator cap and install the tester and pump up the cooling system and then you watch for where the coolant is coming from. Look closely at your water pump, intake manifold gasket, radiator, heater hose coupler on the intake manifold, and coolant hoses. Those are all the common leak areas.

I have a 1999 jimmy with 115,000 miles and I,m hearing about the intake manifolds leaking antifreeze what concerns should i have with my jimmy and what type of antifreeze should I be using

A leaking manifold could cost you a VERY expensive repair. I recommend getting it fixed as soon as you can. And with the antifreeze...seeing how it it a GM it should take DEX-COOL. But look under the hood and look for a white sticker and it should say "This vehicle takes DEX-COOL coolant. Do not mix with any other coolant" and if not the cap for the coolant should say so. If so, then obviously you need DEX-COOL or universal coolant. Universal will not harm anything, but I would use the manufacters reccommendations just on the safe side.

1999 GMC Jimmy Running Hot w/ Engine coolant reservoir empty

I guess the burning question is , where is the coolant going.
Is this a 4.3 engine? How many miles does the vehicle have?
Has the intake gasket been changed?
I'm guessing a can of "Bars Leak" may cure your problem.
Let me know.

Coolant leak

There is a hard line on the back side of the engine block and the hard line sometimes cracks. i would check that line and see if it is leaking. If is not that hard line check your heater core hoses.
