Engine was slightly knocking when i drove it

sounds like the water pump. BUT check your hoses first. if you had a weakened hose, it may have split... but the gurgling issue sounds like the pump stopped. good luck!

Sounds like it may have blown a hose and you lost all the coolant. IT could also be that the puddle you drove through caused the head gasket to blow. At any rate, this is not going to be cheap.

When you work with such problems make sure you change your seal's oil leaks and give smoke cos' it is leaking through. Make a real engine overall.

1t ck the fluids. Check the heat shields on the exhaust for secureness. Any exhaust leaks or vacuum leaks?

Okay, it may be due to overheating, that may be the noise you heard, lets hope. first allow engine to cool, open radiator cap or the resivoir cap, which ever is the fill, remove the bleeder at top hose and fill radiator slowly until coolant comes out bleeder.

note if water pump was replaced due to leaking and engine was overheated at that time then it may be a good idea to replace the thermostat .
after filling is done start engine and allow it to run. watch temperature if temp start to climb past half way shut engine down and let sit for 5min. then restart and check level, in res do not open cap . feel air from fan and see if it is getting hot, this may take up to a half hour but do not drive,

A few questions, does this jeep have an electric fan?
when you heard the knocking was engine temp hot?
If you start jeep cold does engine knock?
Did this jeep get a new thermostat with waterpump job?
did it overheat when pump went bad and why did water pump get replaced?

sorry for all the questions ,just trying to get all the info to help you .

Theres a neoprene chain keeper inside front engine cover if that was broke loose in there it might have wore your belt to the point that it broke

• Hi, I can help.
• When your water pump goes bad it will begin to grind. I had one I let got far to long and it sounded deafening when I opened the hood. You can open your hood and listen and see for yourself. The water pump is on the belt line, left side under the hood, last pulley toward the rear.
• Now if your asking can an oil change effect the water pump? No, not at all. Water pumps go sporadically.
• It would be odd that you heard no noises before the oil change and now the water pump is loud enough to take notice after the oil change. The bearings usually go a little slower than that.

• I would be interested in some more of the details to this. And what your overall concerns are. I'd be happy to further. help. Otherwise get a second opinion on your cars condition.

• Hope this helps and thank you for using FixYa.

sounds like you may have blown the head gasket is there water in the oil?

take rubber hose and place near ear use as stethoscope, pin point noise, and pull apart, till problem is located. buy manual

If you can be more specific about the engine knock it might be helpful. I am assuming this knock happens after the engine warms up and can be heard while the engine is under a load. If it is a strong knock sound then it would be a crank shaft bearing. You may want to check the oil. Check for level and condition. If there are water droplets on the dip stick or anti-freeze in the oil, or oil in the anti-freeze, you could have a bad head-gasket. Redused oil pressure, pressure testing the cooling system, doing a cylinder compression test, could help in figuring it out. Also it is possible that it could be piston slap or the fly wheel is hitting inside the bell housing.
