The water pump bearings can go bad. Look for the belt to begin moving laterally or chatter on the water pump pulley. You may also see metal shavings beneath it.
If it is, change the water pump. It is a rather simple and inexpensive but important fix.

Recent head gasket repair. leaking coolant and fuel


Sounds like one of 3 things.... (none are good)

Someone made a mistake on a freeze plug and thats the leak.

The water pump wasn't installed properly, leaking from the base.

The block is cracked near the water pump.

As for the smell of fuel..... something was not re-installed properly and you have a fuel leak.

Sorry this was not a solution as much as it was bad news.

Code 410


code po410 on a 2004 gmc envoy is that there is a problem with the secondary air injection system, you will need to check the fuse located in the engine compartment first, the next step is to start the truck cold and listen for the air pump to turn on for a few seconds, this will sound like a jet engine but not that loud, after it runs for 5 min and you dont hear it then you may have a bad pump which is located under the driverside on frame but if you hear the pump then you may have a bad valve, this valve is located on the exhaust manifold area and has a hose from the pump to valve, remove the hose and check for water, drain any water in the hose, also remove hose at pump and drain, the most common cause for this code is the valve is not opening and the air pump gets water inside and goes bad, thats the po410 code. a quick note; if fuse is blown look under truck near pump and check relay as it fills with water and blows fuse, if this is the case replace relay and blow water out of connector.good day.

1995 lexus es 300 . I have replaced the water pump. the thermostat, the radiator and it runs at normal temperature, but when I shut the engine I hear it gargleing, like it`s a little hot. what do I do to...


Make sure your radiator cap is new as well. I sounds like you may have to bleed the air out of the system. There is a bleeder screw near the water inlet neck that is for this purpose.

Doesn't seem to be getting fuel. Has Gas but may not be pumping. How do I check pump


Have another person with you in performing this test: Have other person stand near rear of vehicle near fuel filler door, turn key to on position (DO NOT START). If fuel pump is working, there should be a short hum (or buzz). It may be necessary for helper to kneel near ground in order to hear fuel pump. If there is no sound, check the fuel pump relay located under hood in master fuse block. To check if relay is bad, use a jumper wire and insert into slots that hold relay. If fuel pump makes a sound, then replace relay.

My engine is making a gurgling grinding sound near


Is the coolant system completely full? It may have air in the system and what you are hearing is the air trying to pass the water pump.
You could also be hearing the valves and air flow through throttle body.

Spinning sound when pushing gas peddle, sitting


try it with the belts off you can start it and see if the spinning noise goes away then it's accessory's like bad alternator or power steering pump but dont run it more than a minute or two or it will start to overheat. and if it still makes spinning noise make sure it's not coming from the transmission /use a broomstick against the engine block near each piston to hear the condition of the pistons if there scored real bad it makes noticable diff noise than a diff piston will make. check the front of the engin the water pump sometimes needs to be replaced because the bearing in it drys up and fails / there sealed bearings in a water pump than go make noise . good luck give you stuff to think about.
