![]() Be careful, as the fluid can become extremely hot to the touch. Once the bubbles stop, check to see if there are any leaks and take the car for a test drive.You won't be able to see anything in the crankcase thru the drain plug because there's a draft baffle in the way. Typically a crack or leak in the oil cooler would put oil in the coolant, because oil pressure typically runs higher than coolant pressure. You’ll likely need to squeeze and release the hoses to remove any trapped air bubbles in the hoses as the car cycles the new fluid through the engine and radiator. I'm assuming that's one of the tubes thru the oil cooler. Start the car with the radiator cap still off.Check the radiator cap to see how much pressure to apply without going over this number. Check the Radiator Cap for the System’s psi. Push down and twist the connector clockwise until you feel it click and it locks in place. Reconnect all the hoses to the new radiator. Tighten the coolant pressure tester to the adapter or the radiator or coolant reservoir.Remove the tape from the hose that housed the old thermostat and replace it with the new one.Insert the new radiator and bolt it back into place.Install the fan bracketry on the new radiator.Remove the fan bracketry from the old radiator.Holding the top of the radiator, remove the top nuts and bolts holding it in.Another is in the oil cooler, if it is an oil-to-water heat exchanger. Find the bracketry holding the blown radiator in place and remove the bottom nuts and bolts first. One is at the head gasket where oil can leak across the top of the head to the water passages (or into the cylinder or out the edge of the gasket) if the head isnt properly torqued of perhaps if there is corrosion in the cooling system.This causes a loss of compression as compression leaks from one cylinder to the next and can cause exhaust gasses to flow back into the intake. PD diesels some times comes with EGR cooling system, where emission gases flows from exhaust manifold in to intake pipe, and cooling system ment to cool down those gases. Compression leak between cylinders: Rough idling, misfires, and a loss of power may indicate that the head gasket has failed between cylinders. Some cars have fans mounted to the radiator, so you’ll need to disconnect the fans. PD (pump duse ) engine injector do not goes near coolant nor oil lines. The easiest way to identify if you have a coolant leak is by checking underneath the engine for any puddles that are forming when youre parked.It can also cause the coolant to leak into the combustion chamber and burn. Plug the holes by taping over the outlets. A blown head gasket may cause the oil to leak into the cooling system.Once drained, remove the remaining hoses connecting the radiator to the rest of the engine.Drain what’s left of the coolant from the radiator into a bucket by loosening the hose clamp near the base of the radiator or unscrewing the drain plug.Let the car rest and cool for 5-10 minutes.
