Radiator Removal & Installation for a Fiero
Warning: Make sure the engine is completely cool before you install or remove your radiator.
Note: Late model vehicles use spring type radiator hose clamps. If you reuse these clamps, be sure that the hose is installed on a clean, dry connection. If the connection has been painted or coated, scrape it down to the bare metal. Do not try to reuse these clamps on aftermarket hoses. Instead, replace them with conventional worm drive type clamps.
Before you start, be sure to have a flare nut wrench available to remove the transmission cooler lines (automatic transmission only), and a drip pan to catch any spills.
Disconnect the negative battery cable from the battery.
Drain the cooling system.
Disconnect the overflow, heater, and upper and lower radiator hoses from the radiator.
If you have an automatic transmission, remove the transmission cooler lines from the side of the radiator. Do not twist the lines or damage the fittings. We recommend you use a flare nut wrench rather than an open-end wrench.
Plug the ends of the disconnected lines to prevent leakage and prevent dirt from entering the system.
If you have an engine oil cooler, disconnect the lines on the opposite side of the radiator, as described in Step 5, above.
Unbolt and remove the fan shroud. You may only need to remove the upper portion for most service operations.
Remove the radiator mounting brackets, if you have them.
Lift the radiator from the engine compartment. Be sure not to contact the fan blades.
Before you install the radiator, replace any damaged hose clamps and/or radiator hoses.
Installation is the reverse of removal. To install your radiator, follow the steps above in reverse order.
