Junk In My Coolant

[Enes]

you can also do compression test while you have the gauge hooked up on the coolant side, and when the engine cranks there should be NO gauge muvement at all.

NO smoke what so ever, out the exhaust at any time even at WOT.


What I don't get is since we put this car together I've had this heating issues (2 summers of this crap)

I've replaced my head gasket 3 times. And replaced the Head with a new one, I've replaced the thermost 4 times, and put on 3 radiator caps.

And Nothings Changed during that time. I've always run hot, and I've always had to fill up my coolant when the temps went up. And like everyone seen my car doesn't smoke at idle, cruise, or WOT...

tried different radiator? how did you clean your current one?

Screw the compression tester hose into each spark plug hole and apply direct air pressure to each cylinder one at a time with the cap removed. If you see bubbles, you have a problem.

Never cleaned it. - I actually found my Coolant Cleaning stuff/flush stuff. And I brought that with me. Don't know what all it intalls but at least i have it if need be.


My current Radiator has 164K miles on it. - But I took my aircompressor and lightly blew air through the fins so that the junk got blown out (did that when I was first trying to figure out the problem?)

I am planning on buying a fluidyne shortly - but it's just a matter of Time & Money when that happens?

I was thinking that the Gunk might be from something that's clogging the system?

The only problem would be where would that be possible? and what possibly could it be?

I know we had problems with my Heater core when we first assembled the car. Where the coolant would leak into the car.

but we found out it was coming from the lines that go into the fire wall.... They attachement points weren't round so when we put the hose's on there the clamps weren't creating a good seal. So we had to take the hose's off and round out them Heater Core lines. After that I haven't had coolant leak into the car or from that area since.


The only other things I've changed in my set up is the Magnus SMI. I had to lengthen the Lines that go to the TB and I'm also now running a 1G TB instead of a 2G one?

Otherwise I can't think of anything else that's been changed since this motor was in my GS-T that pertains to coolant system?

A/C's gone?

do I do it with only 1 spark plug out at a time? or all 4 out and then 1 at a time?

all of them out.. makes it easier to turn ;).. plus that way you can isolate which cilynder is leaking ..

It would take time for the bubles to come around out.. so i say just keep it preasurized at X preasure and watch the gauge while you are doing the compression testing.. both gauges that is...

and your engine compression should be at 160+ or whatever...
but your coolant preasure should be the same, not raised or droped..

All out, 1 cylinder at a time. Crank the piston down to the bottom of the bore first, just in case you have a hairline crack down in the bore somewhere. Pressure it up with compressed air and let it sit for awhile and see what happens.

Don't crank it over, let the compressed air do the work for you.
