help with radiator replacement

Yeah, I just found a stock radiator at Oreillys and Autozone for under $200.00. This car has no shroud nor did it come from the factory with one so I will probably go that route. Thanks,Guys.
Nothing we buy at a parts store is really the same as what the factory installed.
If you have the original, have it cleaned and repaired if need be.
The metal is heavier. The seams made better. Fits exactly as it should. Accepts a factory shroud.
A slight rise in temperature with weather is normal.
A rise in termperature could be a cap not hold to rated pressure.
Could be a small leak under pressure somewhere else.
Narrow down the circumstances it occurs.
