Was filling my recently rebuilt d16a6 up with fluids today, car is up on jacks in the front and I start filling the rad up, get about 2L in there and I start hearing a drip.

Look under the car, coming from drivers side rear, throw a bucket under there and climb under right away, theres a little steady stream that seems to be coming out of a little hole that is directly infront of the alternator

I just checked on my spare motor here and at the bottom right of the waterpump is a hole, kind of on an angle, on this motor here it wasnt plugged either

Is something supposed to go inside this hole or something? Obviously its not supposed to leak, but its not a threaded hole so I dont know what to do or what is the oem setup like

Thanks guys

 

I goes into your IM and out to your raditor.

 

Water pumps usually have a hole in the bottom of them near the pulley. When this hole is leaking it means your waterpump, bearings/seals are shot and the pump needs rebuilt/replaced.

 

Yes and it is called a weap hole.

 

the waterpump was new less than 12k ago, ran for one season only

the car HAS not run since rebuild, Im just filling up the fluids and it leaked

 

Its not bad though, its basically new, oem pumps dont blow after one season

The pump ran fine also when the engine was pulled, new internals instlaled and now put back into engine

If I just plug this weep hole with some jb weld, will the water just go somewhere else or will it stay contained in there?

dont jb weld it, that hole is there so u know when the pump is fucked. MY truck started doing this last week lol. Just get another one before your bearing takes a poop.

 

Would definately recommend replacing and Honda OEM water pump is not too expensive considering alternative of replacing a block or engine.

 

I just replaced it though, so I dont beleieve its the problem, I need a running car and Im not paying for something I dont think is brokn

 

its the water pump.. my friends rx7 just did the same thing yesterday.. if you plug that hole, the water will go into the engine.. go ahead.. plug the hole, buy a new engine when you get hydolock.. just buy a new fing water pump and quit bitching..

fing checker sells em for 27 bucks.. cheapest and 31 bucks most expensive.. thats shucks if your east coast, and kragen for you cali folk..

?</TD></TR></TABLE>if there is no coolant going through a pump that has previously had coolant flowing through it, then the seals will dry out and hence your leak.
replace the pump immediatley to avoid ruining your newly rebuilt block

id just replace the pump, it means water is getting past the seal. if you plug it water wont go in the engine(its already there), but evently the bearing will go bad and u'll break the timing belt because it'll sieze. now i dont know about u but id rather change the water pump rather than change the engine

If you don't think it's "broken" then please explain how you think the coolant is getting past the seal.

I dont get it man. It seems that lately you dont want to spend a dime on this car! Just like in your tie rod thread...

From your description of where its leaking from, you need a new pump.

 

Just like the old commercial,"pay me now, or pay me later". Replace a cheap pump or an expensive motor, your choice! Get a pump man!

 

I had the problem before with my stock motor. I just use BARs LEAK and it stop leaking.

Is it possible that the water pump to block gasket (o-ring) was installed poorly and it's causing the leak?

Yes. If some other cheap silicone sealent was used other then Hondabond that could be part of it as well.

 

Probably not installed, plug the ****** if the pump is that new

Hey man it work for me and I didn't really care about my stock motor since I had a D15B sleeping in my garage.

 

i had this same problem on my motor, and the problem was that one or two of the 4-5 bolts that hold the pump are longer then the others you MUST make sure the blots are in the right holes and to torque them to spec

 

did you fix it?

 

JB weld fixed it, I just plugged the hole with it, let it set overnight and I will fill it tomorrow
