    Never had an issue, car was sitting for a week in below freezing temps.. Radiator did not have anti freeze just straight water.. Would that make water pump leak?

SOURCE: Replacing water pump in 98 Lex GS300

Removal of the crankshaft front pulley/damper can be removed without any damage being caused to the cam belt.
They are a good fit on the shaft, I personaly use a lead tup, weighs 2lbs and will not damage anything if used properly.
Tap equaly all the way round the pulley, that should be ok.

SOURCE: How to replace a water pump on a 1999 dodge

so i just replaced my water pump today on the same car, mine is a 5.9 magnum. I drained the whole system before i started working on it, next you have to take off the fan, if you look on the inner side of the fan there is a big nut there, in order to loosen that i put to bolts into the holes on the water pump pulley and used a thin screwdriver for leverage, while putting pressure on that, i loosened the nut, be careful not to slip cuz those fan blades are dangerous. but once you have removed that nut from the pulley take out the four bolts holding on the housing, pull the fan and the housing out at the same time. next remove the belt, after that is done, disconnect the hoses from the water pump, there are three, one on each side and one on top. there are a total of eight bolts holding the pump on, keep track of them because they are different sizes. But that is how i removed mine. It was all farely simple i am a girl and i managed to do it so i think you should be fine. Hope it works for you becuase it didnt work for me, i now think that it is my head leaking, if you know anything about that let me know.

Possibility of a cracked block. how can i be sure/


Vehicles: Any with the above symptoms

A cracked cylinder block will cause either:
(a) motor oil contamination of engine coolant
(b) coolant contamination of motor oil
(c) white exhaust smoke, due to coolant seeping into one or more cylinders.
(d) more than one of the above
(e) all of the above

Oil infiltrating into coolant is easy to see - drain some coolant out through the pepcock at the bottom of the radiator, and place it into a styrofoam coffee cup. Oil droplets floating on top of the green (or orange) coolant are easily seen. Or visualize oil by looking into the top of the radiator through the radiator cap.
Coolant infiltrating into and mixing with motor oil will permanently damage the engine (seizing it up through loss of lubrication), and must be prevented.
A leak from above the front suspension is, as physicians like to put it, "nonspecific", with the most likely cause a water pump seal or hose/hose connection.
A leak from near the fire wall will usually be a heater core hose, or hose connection.
A coolant leak on the same side of the engine as the water pump is a leaking water pump or water pump seal until proven otherwise.

To rule out everythng else, here's the 1999 Honda CR-V Troubleshooting Guide for Coolant Loss/Coolant Leaking:

Priority Action Part Type Cause
1 Inspect Water Pump - Worn, Cracked or Leaking Water Pump, or Water Pump gasket.
2 Inspect Head Gasket - Leaking Head Gasket.
3 Inspect Radiator - Leaking Radiator Hose(s).
4 Inspect Radiator Cap - Worn or Damaged Radiator Cap.
5 Inspect Radiator Hose - Ruptured, Cracked or Leaking Radiator Hose.
6 Inspect Freeze Plug - Leaking Freeze Plug(s).
7 Inspect Intake Manifold Gasket - Leaking, Worn, or Damaged Intake Manifold Gasket.
8 Inspect Water Outlet - Cracked, Leaking or Damaged Water Outlet.
9 Inspect Heater Control Valve - Leaking or Faulty Heater Control Valve.
10 Inspect Radiator Drain Pepcock - Loose, Damaged, or Faulty Radiator Drain Pepcock, or Pepcock O-ring.
11 Inspect Engine (DOMESTIC ONLY) - Cracked Cylinder Block Leaking Coolant into at least one Cylinder, causing white exhaust smoke.

Coolant leaking from above front suspension


If it's from the front of the engine, the water pump may have failed. Check for water coming out from the bottom of the pump.
Was the overheating caused by low coolant level?
If not the pump, check your engine freeze plugs and hoses.

TRUCK IS RUNNING HOT AND WATER IS LEAKING


There are many locations water can leak from. Worst case is the head gasket its blown and the water is leaking into the combustion chamber or the block. Best case check hoses and radiator. Also make sure no air is in the system. Check freeze plugs as they corrode out.

Replacing water pump in 98 Lex GS300


Hi,

I bought this old car and the seller did not provide a manual book with it, I got the luggage compartment not working over a sudden after i bought the car, also the keys are not turning, so i can't open the luggage at all. I tried to look for the fuse box maybe i could find the fuse burnt but i can't find the wright location or the fuse.
I need a diagram for the fuse box if it's inside the car not at the back, and if it's on the back how can i open the lauggage then?
