basically, im replacing my timing belt, thermostat and water pump. i was wondering if i could just fill up the radiator and block and no worry about air in the system.

i have a 96 civic with a boosted d15b...pretty much the same...i change the engine oil and flush out the coolant myself...basically, the radiator flush thing will have no problems just twist the drain...then add a new coolant...but flushing out the block is a different story...after you flush the block, you have to wait for a while to let the residue reside then add another set of second-grade oil and additive, start the engine and leave it running for 30mins then flus it out again, now you put the high-grade oil and additive which fits the engine preferences perfectly...you have to chose a variety of oils and additives which fit the preferences of your block...you cant go and purchase any fluids which are not designed for your engine...there are classifications and viscosities of different oil brands for specific engines, unfortunately i am not familiar with that...

if there's nothing wrong with your water pump and thermostat why change them? just flush the radiator and block and it's good to go, maybe do that once a month...

what do you mean "if there's nothing wrong with it"? its part of the service. you change all three at the same time, and how would you bleed the cooling system?

there's a drain somewhere, you just have to twist it...are you gonna clean your radiator afterwards? maintenance and change of parts is actually a good thing..make a schedule for that, especially the oil change...

it's not really neccessary but if you have to,just remove the hoses connected to the block and rev your engine, it'll flush air out but be careful not to rev the engine too much coz it might blow out the oil and it'll be a nasty mess...

dont do it that way ...to get your fans to turn on and get the fluid through the block rev it between 1 and 2 grand til the thermostat opens

theres actually a bleeder valve on top of the block, above the hose that goes to the radiator. i just open it and when it squrts out fluid, i had air in the system. when the fluid ran out of the valve with no sudden burst of air, the system was air tight, thought it took me about 2 hours to bleed it cause i had to drive it around to put a load on the engine to get the pressure up.
