Hey Jack. I haven't checked the manual but what is the recommendation to change the radiator fluid? I'm at 80k now and I don't have any heating problems.

Prestone Radiator Flush Safe?

on the bottom right of the radiator (driver side) there is a drain plug
I drained my SVT cooling system and only got maybe a gallon of brown liquid. Does opening the drain plug completely clear the system or does the thermostat prevent engine-side coolant from getting out?

Also, I put in a container of Prestone Radiator Flush this morning (and topped up with water). Now I can't get back in the garage to flush the flush. Will it harm the cooling system to leave the Prestone Flush in overnight?

I will not worry about leaving the flush overnight. You really should only run the engine like 20 minutes min with that inside. That is what the instructions say.



Also let the car heatup a little to normal operation that way the thermostat will open

and now you have access to the other coolant side.

Then let it cool down and buy a kit from Autozone that you can actually install in one of

the heater hoses and connect your garden hose and let it flow until from the radiator

the water come's out looking clear.

Getting ready to do mine. It's got 80k miles, so I guess it's time. I usually use one of those kits, but I'm not sure which hose to put that on, the heater hose going to the overflow tank? They recommend the hose coming from the firewall which is near impossible to get to. Also, did you remove the upper hose to flush it from? Thanks.

Alright let me get this straight, if I am going to flush the cooling system and run distilled water and some water wetter, I basically need to open the drain on the bottom after the car gets hot and is still running and add the warm not "ice cold" water into the coolant overflow/resivoir>sp? and wait till the drain is flowing the water clear?
