Can be lots of things,,,
overheated engine, warped head, and now head gasket blown.
or cracked block.
or cracked heads.
we find this doing tests. want to test or gue$$.
do a compression test or the cylinder leak down test.
on DOHC we do the latter, by hand.

SOURCE: What is the Radiator Cap Pressure for Isuzu Rodeo 1996 2.6-4cyl

Cap pressure is best determined by going to the auto parts store and buying a new one. You can ask the counter guys to look it up online before actually buying.
Most radiators today run 15 PSI, but the cap is just a safety valve, and has nothing to do with controlling the actual pressure. The thermostat does that, and if your having boil over problems, then you need to be looking to other causes (plugged radiator, bad water pump, etc.).

Pipe from radiator to exhaust and engine block


That there are deposits (probably from using tap water in the coolant system instead if distilled water) which have built up. They are built up in the entire cooling system including the radiator and heater core as well as the cooling passages inside the engine. The entire system needs to be flushed...it may take multiple times to completely clean it out. Then the system needs to be refilled with coolant and distilled water

How to replace water pump on 1991 pontiac quad 4


2.3L Engine
  1. Disconnect the negative battery cable
  2. Detach the oxygen sensor connector.
  3. Properly drain the engine coolant into a suitable container. Remove the heater hose from the thermostat housing for more complete coolant drain.
  4. Remove upper and lower exhaust manifold heat shields.
  5. Remove the bolt that attaches the exhaust manifold brace to the manifold.
  6. Break loose the manifold to exhaust pipe spring loaded bolts using a 13mm box wrench.
  7. Raise and safely support the vehicle. NOTE: It is necessary to relieve the spring pressure from 1 bolt prior to removing the second bolt. If the spring pressure is not relieved, it will cause the exhaust pipe to twist and bind up the bolt as it is removed.
  8. Remove the manifold to exhaust pipe bolts from the exhaust pipe flange as follows:
    1. Unscrew either bolt clockwise 4 turns.
    2. Remove the other bolt.
    3. Remove the first bolt.
  9. Pull down and back on the exhaust pipe to disengage it from the exhaust manifold bolts.
  10. Remove the radiator outlet pipe from the oil pan and transaxle. If equipped with a manual transaxle, remove the exhaust manifold brace. Leave the lower radiator hose attached and pull down on the outlet pipe to remove it from the water pump.
  11. Carefully lower the vehicle.
  12. Remove the exhaust manifold, seals and gaskets.
  13. Loosen and reposition the rear engine mount and bracket for clearance, as required.
  14. Remove the water pump mounting bolts and nuts. Remove the water pump and cover assembly, then separate the two pieces.

My 2001 isuzu rodeo is losing water from the radiator, no sign of leaking. over heating (of course), water from resevior is not feeding into radiator at all like suppose to.


The reservoir is used to catch overflow coolant after the coolant heats up and the cooling system builds pressure. Since you said there are no visable signs of a leak, if your coolant doesn't have a correct mixture of water/coolant or if you're just using water (I've seen this done many times) it will vaporize. Ethylene glycol has a high boiling point water doesn't. If you have a 50/50 mix you're good and I would suggest that you may have either a blown head or intake gasket and your coolant may be either seeping into engine or blowing through exhaust system. First check your dipstick, if your oil is really black change it, if it's muddy looking it has water in it. If not start your vehicle let it warm up for a few minutes and check your exhaust for any moisture dripping from tail pipes and you would smell a distinct antifreeze smell too. I would also first open the drain valve at the bottom of my radiator and run water through your radiator neck and run your vehicle until the coolant is flushed out and only clear water is coming out (be sure to note the condition of your coolant, if there's a lot of **** or rust in the system, your radiator cores may be stopped up and not allowing flow to pass through them) then replace with 50/50 coolant mixture.

How do I replace a water pump on a 1999 malibou with a quad 4?


Water Pump REMOVAL & INSTALLATION CAUTION
Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old. 2.4L Engine

COOLANT LIGHT STAYING ON BUT NOT OVER HEATING, ADDED 2 5 GALS HALF AND HALF ? WHAT DO I NEED TO DO


The coolant light is warning low coolant level. If left unchecked then overheating will follow. Find out where the coolant is leaking from. Look around the engine bay for a brown stain in a arc perpendicular to the water pump pulley. Water pumps as they age often leak through the water seal at the centre and as the engine runs this water spins off the pulley around the engine bay. Check all pipe unions and the radiator core for leaks. Then check the interior heater unit supply and return pipes and unions - check the foot well carpets fro tell tale dampness. Check the filler cap rubber seal is good - enough to hold the coolant pressure. Check the inside of the oil filler cap for white mayonnaise build up - if there is it could be head gasket leak. Lastly check the exhaust for white gases (steam) and remove the plugs one at a time to check them. If water leaks into a cylinder(s) the plug(s) will look clean

Oil leaking into coolant -- not head gasket


That vehicle has the transmission cooler built into the radiator. You may not be leaking oil into the coolant, but transmission fluid, they both make the same mess. Replacing the radiator will probably fix your problem. Let me know if this helped.

How to replace the water pump on 1993 oldsmoblie achieva.


2.4 enigine is the harder of the 3 enignes. it will need a timing chain to be removed and a coolant tube in the back of the engine to be removed. this job on the book calls for almost 7 hours.

if its 3.3 or 3100 its alot easier.

3100 is just 4 10mm pulley bolts and 5 or 6 small 8mm water pump bolts.

3.3 is alittle more work, but same concept as 3100 engine. more owkr only cause its in a tighter area.

good luck,

EXHAUST LEAK INTO COOLING SYSTEM?


Sounds like you have a partially plugged radiator. Try flushing it out and see if the problem changes at all. When flushing, force water to flow backwards from the normal flow direction this usually frees up some of the debris built up on the core passage ends. If you must, remove the radiator to do this. Depending on accessability, I usually just tape up the end of a garden hose and put it into the outlet on the radiator (but have gotten as radical as using a pool pump and lime out to do this job!
Is there any coolant in the engine oil or trans?
