The cooling temperature on the 2002 Grand Cherokee is maintained by both the radiator and the inundate pump. The radiator on the 2002 Grand Cherokee can crack in persuaded places, requiring replacement.
Instructions
1. Spray any spilled coolant puddles with water, until the coolant is heavily diluted and is not showing up green in your driveway.20. Pour the coolant from your drain pan into the empty coolant bottle you filled the engine with.

Remove the radiator coercion cap from the top of the radiator. Complete distortion of the facts below the front of the Jeep and slide yourself in position to access the lower radiator petcock. Slide a remove pan under the petcock with the majority of the pan remain the radiator. Regulate the petcock, with pliers whether needed, and sanction the radiator to filter into the pan.
Push the quick-connect factor over the becoming on the border, then install the border. Push the path onto the radiator with one handwriting, and remove the quick-connect factor with your for love plam. Repeat this action to attach the moment transmission wrinkle onto the radiator becoming.12. Sufferance the hose draining into the pan for the vitality of the project.
4. Elevate the Jeep off the jack stands, then remove the stands from below the Jeep. Lower the Jeep to the ground slowly. Slide the upper hose clamp off the radiator and approximately 6 inches rearward with pliers. Install radiator locking pliers or flat-nosed vise grips onto the upper radiator hose to pinch the hose shut completely. Pull the upper radiator hose off the radiator.
5. Remove the radiator cooling fan electronic connector by fist. Remove the gift steering fluid reservoir from the top fop of the radiator shroud with a ratchet and socket. Establish the reservoir to the side of the shroud. Remove the radiator reservoir hose from the filler neck by fist.
6. Remove the radiator fan shroud mounting nuts from the radiator core block with a ratchet and socket. Pull the fan shroud and electric fan meeting straight upward and elsewhere of the engine compartment. Establish the fan meeting elsewhere your daily grind earth.
7. Remove the automatic transmission lines, whether equipped, from the dated radiator using a quick-disconnect stuff #6935 or equivalent. Push the quick-disconnect object onto the transmission becoming, then pull the becoming off the radiator. Repeat this for the moment transmission becoming. Remove the mounting bolts from the upper radiator core block with a ratchet and socket, then remove the radiator core abutment. Locate the core abutment gone your daily grind environment.
8. Detach the radiator from the radiator-to-air conditioning condenser meeting brackets, whether the Jeep is equipped with air conditioning. Remove the bolts attaching the radiator to the brackets.
9. Pull the radiator straight upward and gone of the engine compartment. Fix the radiator with the hose openings upward, so that it does not spill or leak antifreeze on the ground. Fix the original radiator on a mammoth group of cardboard, or in the box it came packaged in, directly ensuing to the dated one. Transfer the transmission Trimmings from the ancient radiator to the fresh, unless the late radiator came with virgin Trimmings. Tighten the Trimmings snugly with a ratchet and deep-well socket. Bag the transmission gap caps on the fresh radiator to plug the transmission wrinkle holes on the mature radiator.
10. Turn the radiator filler neck on the getting on radiator counterclockwise, using colossal pliers whether needed. Cause not squeeze the plastic neck indurated or you Testament hole it. Install the filler neck onto the contemporary radiator and tighten it snug, using pliers provided needed. Install the recent radiator straight downward into the two backside mounting holes on the front frame.
11. Install the automatic transmission lines, whether equipped, onto the inexperienced radiator using the quick-disconnect belongings to help you.3. Brisk the petcock after encompassing five to seven minutes, or until the radiator has solitary a mere thin void contour or drip. Act the extract pan subservient the lower radiator hose and pull the hose clamp off the radiator with pliers. Pull the lower radiator hose off the radiator and remit the engine to extract into the pan for approximately five minutes.
Install the radiator-to-air conditioning condenser bracket bolts and tighten them snugly with a ratchet and socket. Install the upper radiator core backing and tighten the bolts to 86 inch-pounds with a torque wrench and socket. Connect the upper radiator hose, then remove the clamp from the hose that you hog, pinching it shut. Slide the radiator hose clamp over the hose where it joins to the radiator using pliers.
13. Install the electronic cooling fan and shroud onto the contemporary radiator. Tighten the shroud bolts to 31 inch-pounds. Connect the cooling fan electrical connector by handwriting. Install the faculty steering reservoir onto the original radiator fan shroud, and tighten the mounting bolts snugly. Install the radiator coolant reservoir hose to the filler neck on the fresh radiator.
14. Elevate the front of the Jeep with the jack and accommodation the jack stands subservient the Jeep again. Lower the Jeep onto the stands. Deceit underneath the Jeep and slide yourself into position to access the lower radiator hose. Push the hose onto the advanced radiator, then slide the hose clamp with pliers forward to where the hose joins to the radiator.
15. Stand the Jeep off the stands, then remove the stands from below the Jeep. Lower the Jeep to the ground slowly. Add engine coolant to the Jeep until the radiator is completely filled. Install the negative battery cable onto the battery, and tighten it snugly with a ratchet and socket.
16. Start the Jeep engine with the radiator cap off. Check your radiator and transmission fittings immediately and shut the engine off if any are leaking. Adjust the leaky fitting, then restart the engine. Allow the engine to run for approximately 15 minutes. Turn the heater control switches to full fan speed, defrost position and full heat.
17.Check the transmission fluid level while the engine is idling. Determine the fluid level on the dipstick, according to the temperature of the engine: If the engine is only moderately warm, the fluid should be between the "Cold" and "Hot" markings. Add transmission fluid, with a transmission fluid funnel if needed, in small amounts until the transmission is full again.
18. Monitor the filler hole on the radiator as air bubbles escape from the cooling system. Add coolant to continually refill the radiator, until all of the air pockets are removed. Squeeze the upper radiator hose with your hand gently to help push any residual air pockets out of the upper hose. Install the radiator pressure cap and tighten it when you are done bleeding the air out of the radiator.
19. Spray the rear side of the cooling fan shroud and new radiator with a water hose. Remove the Jeep from your work area. Lift the hood on the Grand Cherokee. Remove the opposite battery cable from the battery with a ratchet and socket.
