If it's running hot, most likely it's not getting
good airflow or the radiator has issues, clogged or
too small.
How clean is the radiator? If the vehicle sits, crud
precipitates out and clogs the core. Coolant shoud be
changed at least every two years as the corrosion
inhibitors lose their power.
How many cores does the existing radiator have? The
more cores, the cooler it will run.
If it's a good copper, four or five, more, core
radiator, it can be rebuilt for less than replacement.
If it's aluminum or plastic get ready for the hit.
Mechs prefer to replace, it's quicker and the margin
is better.
