To replace the thermostat on a 3.2 L Isuzu engine, first ensure the engine is cool and disconnect the negative battery terminal. Drain the coolant from the radiator, then remove the upper radiator hose and the thermostat housing, which is typically secured by bolts. Take out the old thermostat, clean the mating surfaces, and install the new thermostat with the correct orientation. Reassemble by reattaching the housing, hose, and adding coolant before reconnecting the battery.
nope has to be the 32 valve engine
Valve clearance for the Isuzu 4HG1 engine is typically set at 0.25mm for both intake and exhaust valves. Proper valve clearance ensures that the valves open and close at the correct time, allowing for optimal engine performance and efficiency. It is important to regularly check and adjust valve clearances to prevent engine damage and maintain smooth operation.
First you want to reduce the coolant level by taking some coolant out of the system.You do this by removing radiator cap and then you locate the radiator drain plug at the front of the car not on the engine side on the driver side front radiator tank. You drain in to a clean pan. Next below the alternator you will see a housing jutting out from the engine that is the thermostat housing.Remove the hose that connected to this housing then remove the two 8mm bolts and you will see the thermostat with a rubber seal. Replace thermostat with new seal. Reinstall reverse procedure. But you will have to bleed the air from system on the coolant return pipe under the coil pack. You will see a 9/32 brass bolt threaded into this pipe.With engine NOT running loosen and wait until coolant flows from the pipe and no more air bubbles coming out .Now top off your coolant. Your finished.
U UNbolt the Outlet---- (Gooseneck) where the Upper radiator hose connects 2 the Engine-- Clean the Gasket-or O-ring surface B 4 U install the NEW Thermostat-BE SURE 2 INSTALL the Thermostat the CORRECT way B cause some can B installed backwards & U will Toast the ENGINE due 2 OVERHEATING.I'd like to add that drilling a couple of SMALL holes (1/8" or 3/32") on the flat part of the thermostat (near where the valve will seat while closed) will allow air bubbles (which would otherwise be trapped inside the engine block when the thermostat is closed) to harmlessly flow into the radiator. This is helpful when re-filling the radiator tank.You will need to drain the antifreeze out of the radiator below the thermostat housing before you remove the thermostat housing or you will have antifreeze going everywhere.
it is ok to reuse the old ones just be sure to pay attention to your torque values, replace any of them that look bent, stripped, or damaged.
What does code 32 mean on Dodge Ram 1500 ,5.9 engine
?
start with checking thermostat
32 ounces of freon for all three engine sizes......
25% means 25/100 = 0.250.25 * 32 ( just 25 * 32 and replace the 2 decimal points )0.25 * 32 = 8=========Like this.25 * 32 = 800Two decimal points to the left.So, 25% of 32= 8====
32
what should replace the question mark and why?
