Hey Guys
I'm near here. I have a 99 Silhouette. I am wanting to do a coolant flush and fill but I have been unable to find ANY quality information about this process. I am hoping to get some detailed step-by-step processes (even images) to help me through this process. Any help would be greatly appreciated. Thank you.

its a pretty strait forward process, i dont think you are going to find pics and such. you just have to find your heater core hoses, smaller ones that go into the firewall. then get some flush chemical and follow the directions. i like to get the hose adapter as well and install that at the same time.

I appreciate the response but I still need a little more info. I'm not sure exactly where the "heater core" hoses are that you refer too. Also, you refer to "flush chemical"...is that the "Flush and Fill kit" you linked on Amazon? A little more info would be helpful. Thank you.

flush chemical could be prestone or any similar thing available at your parts store and the heater core, never done one on a van but should be two tubes going in to the firewall

my pos computer wont let me look up anything right now but if you go on autozone they give you free manuals and you could look for a pic.

I looked on the site and couldn't find the manuals.

I found them, had to register. Thank you.

found a better one, the black rubber hoses are the heater core hoses and the ones going into the hard lines down under the car are for the rear heater core, i would find the one that warms up faster when the heat is on that would be your inlet.

Great picture! Thank you. Are those hoses in the pic the heater core hoses? Could you explain what should be done with the hoses in relation to the flush (your first post was talking about this). Also, do I need to drain the heater core by removing the heater core plug in the picture? Thanks again

for the hoses-you should splice the prestone tee (garden hose adapter) into the heater core line. i believe its the inlet side, check the directions when you get it.

for the plug-not necessary, when you hook your hose up after completion of the tee fitting installation you run the engine with your garden hose on and this replaces everything in the heater with clean water. then you drain the radiator and refill, just remember that there is a bit of water in the engine and heater. so you would probably want to do a quart or two of strait concentrate before topping off with 50/50.
