Fits To A Tee
Q. I got the Prestone Flush and Fill kit. It says to connect the tee between the firewall and the engine. What is the firewall? Is it the radiator or the thing that goes in your car so your heater works? Do you think this will work with a 1988 Olds? The model is 1998. Its a V-6 3.8 liter. Do you think it would work with a 1994 Cadillac Deville, 4.9 V-8 engine? It isn't a northstar.
A. The firewall is the body between the engine compartment and the passenger compartment. Look for two heater hoses that lead to this "wall". They are your heater hoses and that kit is telling you to cut a hose and install their tee into it. It should work on both cars.
