When removing the radiator start by disconnecting the battery's negative terminal. If available, you should also remove the automatic transaxle cooler lines. After that take out the radiator together with its fan ensuring to release the air conditioning condenser from the radiator clips. As you lift up the radiator be careful not to damage either air conditioning condenser or fins on it. Check for any leaks or damages in your radiator. Wash out some of these bugs and dirt by spraying water from a garden hose nozzle at the back of your radiator. Ahead of fixing it, flush out your radiator using a garden hose pipe as well. Also inspect rubber mounts which are found at bottom side of a radiator for any wear and tear and replace them as necessary. To attach the radiator into position guide that is attached to it/fan assembly being sure that bottom side is properly seated into related support made up of rubber mounts. Tighten securely all bolts through which condenser connects with a radiator besides those holding air conditioner brackets close to this cooling device itself. Fill up coolant system with right mixture of antifreeze and water after installing it; then restart engine and check for possible leakage points around gasket components where motor sections meet one another while running normally (in case there are any problems). Once again after normal operating temperature has been reached recheck level within coolant reservoir plus add some more if need be; Finally remember about checking transmission fluid levels regularly as required.
