1995 dodge dakota v6 has antifreeze leak between water pump and block. leak is not at water pump gasket. it appears to be right aginst the block. the leak is on the pass. side right behind where lower hose would attach to water pump. does not appear to be any sort of freeze plug. it looks like it is leaking between the block and the alum. support bracket for the altenator. no residue in the oil. just leaking antifreeze. can see it spraying out when the engine is running. any ideas would be appreciated..

YOU MAY WANT TO CHECK THESE FIRST
make sure your radiator is clear and not blocked in any of the fins and openings and make sure your fan is working
u may need to flush the cooling system-could be blockage somewhere bleed valve should be on bottom of radiator on right side looking at front of truck if u still can't find it just remove the bottom hose on radiator-make sure engine is not hot before doing this u can buy flush kit at any auto store after flushing-put water if-not antifreeze run for 15 to 25 minutes and see if it gets hot if not-drain and put antifreeze in if it still gets hot you may have gasket problems allowing fluids to leak out or hot gases from exhaust to get into you're cooling system check tail pipe for steam
the frost plug wont pop unless youve frozen the truck with only water in the block, if you did and the plug went you'd know.. the rad would have blown and leak extremely. and the block plugs would do more than just trickle under pressure. and for some reason if it didnt pop but it froze then your block will be cracked. or you over heated it badly and warped the heads and now the gasket is leaking.(need more than just the gasket, also need freshly machined heads) I'm thinking you have warped heads, as your truck shouldnt have any pure unmixxed water in it unless it brokedown on you and you had to add it at which point you know you did it and should surmise that thats whear the problem stems from. Good luck Rott.
the black chunks could possibly be from someone putting a stop leak solution into the radiator first drain the coolant system fill up with clean water put in some Prestone 10 minute flush and then drain and put in a flush tee in the heater hose not the one going to the water pump but the one going to the engine block open up the drain hose and run water through until clear and refill with new antifreeze and make sure car runs until all air bubbles are out and then replace the cap
DO NOT DRIVE THE CAR until this problem is fixed! You could destroy the engine.
Many GM V6 engines of 1995-1999 had defective Upper Intake Manifold (UIM) gaskets (this is especially true for 3800 V6 engines). The antifreeze/coolant (especially orange DEX-Cool) will deteriorate the gasket material over time. If there are abnormal exhaust noises accompanying the leak, and/or the oil appears cloudy (check this immediately), you may have a blown head gasket or Lower Intake Manifold (LIM) gasket. Start with the UIM gasket.
The repair is detailed in the Haynes manual for that car ($17 at NAPA and Carquest), and (DIY) will take 5-8 hours plus a new gasket and RTV sealant (parts should be under $40 for all). A shop will charge $250-350 for this job.
