    the plug to the coils is a 8 mm maybe a 7 mm bolt in the middle of the plug.

    take the sc belt off, then in the sc tensioner is a nut, 13 mm if you have a 12 point deep socket it should fit inside. remove nut and slide it off. then theres 2 more nuts holding it on under neath it. taking off the idler pulley on the bracket could help too. 15 mm normal threads on the idler bolt.

    make sure you put that little ground wire back on when you re install it.

    Ok. It's not a split hose. It looks like it's leaking somewhere on the water pump housing and the block???

    I did. I have the hoses off and am down to the water pump so I put the lower hose on it and filled with water and it runs out the back side of the water pump housing is where the light is shining. Now I took the tensioner blacket off so can't fill with water it will come out the elbow hole.

    yes, water pump bolts to the timing cover.

    you need to remove the harmonic balancer then. un bolt the timing cover, you can leave the water pump bolted on it.

    heres a crank sensor how to, http://www.grandprixforums.net/threa...a-crank-sensor you need to remove the balancer this thread tells you how, and the bolts you need for the puller and tq for the crank sensor when you put it back on.

    once the balancer is off and the timing cover comes off. you clean up both sides witha razor blade, then the bottom 2 inches oil pan to the first location dowel smear rtv on the block, then install the new gasket and rtv the other side of the gasket and the oil pan gasket, then install the cover.

    That does not sound too bad. I will need guidance. Looks like the oil filter housing is part of it also or not.? Just looking from the top.

    Thanks for being there!

    it is bolted on there. with the oil filter off i think it will come out, if not its just 4 bolts.

    the gasket kit for this job will come with a new crank seal, do not change it unless you damaged the old seal taking the balancer off.

    old seal is mated to the balancer, a new one can leak for the fun if it. then you get really good at taking the balancer off lol

    a good air gun is nice to have for the crank bolt and the puller. the bolt is super tight.

    I only have an electric impact here so may have to resort to the flex plate hand tool method. Dumb question I should drain the oil then?

    theres a real good chance of leaking some coolant in the oil, the front of th eoil pan will be open, theres a line of bolts pan to cover. so plan on a oil change.

    you can do the "red neck crank bolt removal". breaker bar on the bolt to a jack stand, then turn the engine over, the starter will break it free. theres vids on youtube. search the quoted line up there.

    most of the covers bolts go directly through the block into the coolant jackets. bast to take the lower bolts out first, coolant thats left in the block will drain out via the threaded holes. let that all drain out before pulling the cover off. least chance of spilling coolant into the oil.


    when putting the cover back on you'll want to use thread sealant on all the bolts, this way they cant leak later on.

    this stuff, any brand with PTFE.

    Is this very common? I may fill with water again and make sure it's coming out from behind the lower radiator hose connection like in the photo but the hole area is wet from the elbow coming out of the intake manifold so that corner is wet. But I was sure the hissing in the video was lower.
