Hello,
I have a 1993 Audi 100 quattro cs. I need to replace my radiator, and was going to purchase it online since I was quoted by a mechanic $600 for the part alone. I have seen cheaper ones online, and my brother in law is going to install it. So my main question is besides the radiator, what other parts should I invest in to make the whole cooling system function properly? Hoses, thermostat, etc. I had to replace the heater core right before the radiator started leaking. Thanks in advance!
