Ok, if my intake manifold wasnt mess up and it could be my water pump would I still smell a syrup odor and WHY would it be leaking green antifreeze? especially when the antifreeze I use is orange?
Anti freeze (ethylene glycol) has a sweet odor, as for the color change, got me there. Some anti freeze's are green, have you drained and re-filled or just topped off?
You could have a leak in your heater Hose or Bad Water Pump, Small hole in rad. Do you notice as increase in Temp? Need more info i.e. How old is the car, How hot is it getting etc.
Heck cowboy if thats a Chevy the intake manifold gasket and the water pump is both leakin'. Your coolant bottle has orange and the engine block has green and they have not mixed? If so you will need to get the same kind if antifreeze in both and flush all the old stuff out of both places. Clean new Dexcool orange will show up the leaks really fast. Sounds like you need to pressure test that truck partner.
Okay, I take it you've added orange anti-freeze to your cooling system. If the system originally had green in it- you just did something really expensive. The two kinds of anti-freeze don't get along. Mixing the two together then getting them hot makes them into a gel. SO, what you get to do now is a complete system flush(by taking the whole system apart-heater core, radiator, hoses, heater valve, the works) use some sort of flush product, and get a large tub. Then, after you've gotten an amount of it out, reassemble the whole thing, and with the engine cool-put some more flush agent in it. Then, take a garden hose- and fill the system. once it's full open the petcock and continue to use the garden hose to flush the system until the water comes out clear. Now, close up the system and run the car for a bit and check the bottom of the water pump to see if the weep hole is leaking. There is on just below the pump shaft. If that's leaking, the pump is shot. If that's not, then there could be a cracked head, or a bad head gasket. A few things to check for that are- if when the car is running, are there air bubbles coming out of the radiator(with the cap open)? Does it seem to overheat easily? Have you run the engine hot?
