The bearing in the water pump supports the shaft. When it goes bad the shaft can move sideways. This ruins the seal, causing a leak of coolant. I think at higher RPMs the shaft run out is so bad that the pumps impeller is making contact with its housing., a terrible racket. Get it fixed before you overheat and do some very expensive damage.
Best of luck!

My 93 Geo Metro 1 liter 5 speed runs fine but ifvu


6th post wins, with Injector.
the injector can fail for these reasons.
the problem in car lingo, is FLOODING.
and after doing all that did it run? (my other shoe drops)!

1: the 0-rings bad, on side.
2: the injector is bad, it leaks.
3: the ECU injector drive line is failing. (bad ECU)
4: loss of spark always ends in flooding.
5: ECT sensor bad, sending water temp reading to -40C Siberian.
did you get the FLASH codes from the CEL lamp yet, with the
diagnostic jumper , inserted?
6: bad need of tune up, air filter clogged, spark plugs long ago, dead.
do a tuneup every 10 years, or 60k miles and win..
7: Cam belt slipped, low compression for any reasons. again, the 60k mile tune up wins.

when you crank the engine over, with the throttle at wide open throttle
this ACT, cuts all injections. cranking, this covered in the operators
manual, for UN-Flooding all gas engines. and all EFI engines.
and all Suzuki's' (or Geos)

on old dogs like this, i do compression first.
saving a fortune in parts , time and labor, if bad.
do it WOT, wide open throttle.

cheers !

Engine turns over but won't start


Catalytic converter in the exhaust system might be plugged solid.

It is one of he things you mentioned.
LEAK: Check the water pump itself. The seal might be gone.
CIRCULATION: Check water pump and thermostat.

I did tune up on 5.4 and it will crank but dies immediately


There is only spark plugs

Tune-ups are long gone.back around
1988 some 25 years ago

The coil boots don't need any replacement

You may have created a vacuum leak around an
injector o-ring

Check all your coil & injector wiring positions,may
have switched some of them

1976 VW 2000cc bus, fuel injected, automatic single loud backfire, then dead! Pulling out of a parking lot at around 25 mph, I had a single very loud backfire, then the engine died. The motor will crank /...


I'd check the compression now, before getting involved with anything else. And double check the timing because that would explain a backfire and failure to start.

2000 3.8 mustang waterpump leaks at pipe that goes to heater core


That's the return pipe to the pump from the heeater core.It's leaking at the pump? Is it leaking
from the hose that's clamped on,do you think? That is probably a pressed fitiing into the pump
and if it is leaking around the fitting, and the pump has over 30,000 miles on it, I'd just bite the bullet and replace the pump.
I know.....on a 3.8 it isn't the easiest job. (:^) don-ohio

94 buick lesabre 3800 engine, stalls after 10 mile drive and will not start till cools. replaced TPS, Fuel pumpand filter, cam sensor, crank sensor, and ignition control module.


next time it won't run after it heats up, spray or pour water in crank sensor and see if it will start. I have seen new crank sensors go bad.

Recently I had my 2000 gmc 2500 6.0 liter truck start running rough. I changed the spark plugs, checked the coil packs and replaced the fuel pumpand fuel filter. Still no change....Any suggestions?


ROUGH IDLING CAN BE CAUSE BY MANY THINGS.I AM LOOKING AT LEAKING VACUUM HOSES OR INTAKE MANIFOLD GASKET LEAK.DIRTY FUEL INJECTORS AND WORN ENGINE VALVES WILL CAUSE ROUGH IDLING.ALSO LOW IDLE SPEED CAUSE ENGINE TO RUN ROUGH.

1992 ford explorer. Hit a deer. Messed up front end. Need to replace gasket behind timing chain cover to fix water leak. Already replaced water pump. still have the leak. Can timing chain cover be replaced...


sounds like the engin took a real wack????
i hope you eat that deer!! its cost you dear to fix it?
you could do the gasket in place but its a right old job,,,when mine started leaking i just tiped in a big bottle of rad weld or block weld (stop leak) what ever you call it,,, it stoped the leak dead in its tracks for years (3 or 4 years) till i sold the truck??
as for bad running yes it could be the crank sensor or that water leak getting every thing wet??

Car overheat frequently and at time the engine sound is very loud


Several things can cause this overheating. Have you recently done a:
1. Check Hoses for Leaks
2. Check Radiator for Leaks --- Also, Change Radiator Cap ( can loose pressure there if
cap is bad)
3. Check Water Pump for Leaks. If Water Pump is bad, you will hear a loud noise from it
4 Complete Tune Up? Should be done at least 1x a Yr. Depending on how much you drive the Vehicle. Includes: Plugs, Plug Wires, Gas Filter, Air Breather Filter, PCV Valve, Adjust Timing,
Check Belts -- see if worn
5. Changed your Thermostat & Gasket and have the correct degree Thermostat in the Vehicle?
6.. Had your Radiator Rod and Cleaned out?
7. Temperture Sending Unit (located near Thermostat) could be bad
8. 02-Sensor (Generally located in the Exhaust Manifold - needs a socket with a space in it
to allow the Socket to fit over this top wire of the 0-2 Sensor )
9. Change oil and oil Filter.
10. Change Gas Tank Cap ---

Do all this yearly ( except the Radiator Rod & Clean ( do every 2-3 yrs), and you should not have
any over-heating nor stalling out, etc. and should pass emissions as well.
