Hi guys,

I've been dealing with a major coolant loss in my 96 xlt for about a month now. I bought the truck off of craigslist about four months ago and have been upgrading stuff since then, but am at a loss as to what's going on.

Recently, I put in new gaskets on the lower manifold, valve covers, and intake manifold hoping that might be the problem.

I've tested for cracked block / blown head gasket, but the truck passed the radiator gas test (http://www.uview.com/index.cfm?dsp=productdetail&id=45700&productid=5122). No oil in the coolant or coolant in the oil. I did a partial compression test (my tool doesn't fit in the tight spots on the passenger side and kept blowing out the hose) and the cylinders with a true read were around 150psi.

It does have a squeal/ whine especially when it starts up. No puddles. New plugs and wires. New thermostat.

The next thing on my list is water pump, but would that fit the symptoms?

How else could the coolant get through the exhaust if everything else is solid?!?

I'm thinking the worst now and am really concerned I've got a cracked block. I've already ripped it down to the lower manifold and replaced all the gaskets, but I still have white smoke exhaust and now there's a coolant puddle.

Either I f'ed up the gasket and made things worse or the problem is the head gasket and/ or block.

Was hoping I'd get a bit more time between having to tear it down again.


Just to clarify, if this was something as simple as the water pump I wouldn't have the white exhaust issue, right?

When I lost my water pump there was no white smoke, you would have circulation issues and heating issues not white exhaust smoke. There is no way for a water pump to introduce water into the exhaust. If youre sure its not the heads then it must be a head gasket or block. Im in the middle of a full rebuild myself because of a head gasket.

That's what I figured...

Got the new head gaskets on this weekend. Just need to get the intake manifold and belt back on before firing her up. No cracks in the heads or block, but definitely lacking any RTV. Felt like the previous owner changed gaskets as well, but didn't do a bang up job of it. I found a lot of "easy fixes" on the way in so I wouldn't be surprised if he had reused the head bolts and got some coolant seepage that way. Both gaskets looked like they weren't torqued down properly and had leaks between the coolant ports and cylinders.


Hopefully, tomorrow I'll get her running after reassembly.

can u tell where the coolant is coming from? i had a coolant spewing out from my engine block somewhere, an white smoke was coming from under the hood, my truck barely started, an had no power, i found out i blew out my block heater an coolant was coming out there. its a hard spot to see on the passenger side, but it was an easy fix in the end. was just something u dont think of. i thought i had blown a head gasket at first.
