Replacing radiator hoses

So ive gone a bit modding crazy. Anyways ive decided my modding action plan:

1) All of engine bay
2) Exhaust/test pipes
3) rims, tint
4) Coilover, sways

Anyways im on step one, and almost done. Im going for a red and blue engine bay. So i want to change my radiator hoses to red to match bb's grounding kit (which is great). I know where to get them but im looking for a DIY or a yes or no recommendation. I have no idea if it would be hard or not, or where to even start

So basically im asking, is it easy or hard, and how do you do it?

It's not hard.


You need pliers, #2 Philips screwdriver, 10 mm socket and ratchet, 2 gallon of coolant, 1 gallon of distilled water.
1) Drain coolant (drain cock is on the bottom of the radiator on the passenger side).
2) Remove 2 bolts holding the overflow reservoir.
3) Remove overflow reservoir. Replace 2 small hoses connected to reservoir by squeezing clips with pliers and sliding them away from the ends. Remove and replace hoses, putting clips back in place on the new hoses.
4) Remove upper an lower radiator hoses by squeezing clips at the ends with pliers and sliding them away from the ends. Replace with new hoses and put clips back into place.
5) Refill system with 50% coolant/50% distilled water. You can adjust the ratio to less coolant depending on your climate if you like. System capacity is about 10.5 quarts including overflow reservoir.
a) Refill reservoir tank to MAX line with 50/50 solution
b) Remove driver side intake box to access air relief plug on the back side of the radiator at the top. Remove the air relief plug.
c) Remove engine cover. Remove another air relief plug on top of the heater hose that runs behind the driver side TB and beside the brake reservoir box
d) Replace the drain cock on the bottom of the radiator. SLOWLY refill the radiator with the 50/50 solution. When the coolant begins to come out of the open air relief hole in the radiator, stop filling and replace the plug. Continue filling SLOWLY until it begins to come out of the open air relief hole on the heater hose. Stop and replace the plug and the radiator cap. Rinse overflowed coolant off of the engine (it has a strong smell if it is left on the hot engine). Run the car up to operating temperature and check for leaks. Continue to run for 10 minutes and then shut it off and let it cool. Remove radiator cap and check level. If it's low, remove air relief plug on the heater hose and slowly refill until it flows out. Replace plug. Do this until the level doesn't drop. If you refill very slowly, you won't have air trapped in the system and you wont have to top it off more than once if at all.

You can also just buy 2 gallons of premixed 50/50 and top the remaining capacity off with the distilled water so you don't have to do any mixing.
