Answer 1

A 24 mm wrench will fit. If changing coolant at home, easiest way will be a drain and refill, the petcock is at the bottom of the radiator. Or you can loosen the lower radiator hose, just watch for flying coolant.

Update: Because of the pepper, I would suggest a good power flushing at a local garage, we charge about 99 bucks for a power flush, local garage may be cheaper. The heater core may be clogged bad enough that the pepper will not come out, and require a core replacement.

Update 2: If you can rig up a nipple to attach a water hose to the heater hoses, you can try flushing it at home. Also can do the rest of the cooling system as well, it just will not have the chemicals a power flush uses. To replace the heater core, remove the heater hoses, remove the floor duct under the middle of the dash, and there are four screws that hold the heater core cover in place. Remove the screws and the cover and remove the heater core out the bottom of the dash.

Answer 2

Can't tell you the size wrench to use for the EGR valve, but the flush is easy. On a cold engine, remove the top hose to your radiator. Point it away from the fan at the front of the engine. Put a garden hose into the top inlet of the radiator. Turn on the hose to a slow steady stream. Start the engine, and wait for the block to heat up enough for the thermostat to open, circulating the coolant through the engine. The stat will close, then open again. Let this process repeat itself until the water coming out of the engine is totally clear. Then, shut the engine off, and remove the hose. Replace the hose, and open the radiator. Open the radiator drain plug, at the bottom of the radiator. Once draining is complete, fill with the reccomended amount of antifreeze according to your climate, and engine specs.
Good luck,

i own a repair shop,and i always use an adjustable wrench on the pipe,and as for the cooling system you need to drain all the old anti freeze out of it,and hook a garden hose to one end of the heater core hose and flush it all out,and then flush the whole engine out by running water through it, through any opening you can ,and make sure it all drains back out of it this can take a while if you do it right but it will help the car run cooler ,and put out a better heat inside also,all you do is run water through any hose and any part of the engine that you can on it,and this should flush it out pretty good,i hope this help,s..good luck with it.

Answer 4

You can disconnect the heater hoses and just flush the core with a garden hose, but if it's been without circulation for a while, it's probably in pretty bad shape.
