As far for the crossover gaskets , would you prefer any over the other?
- 02-12-14 04:07 PM #34
I ordered all my gaskets from Chris. I'm actually not sure anyone makes aftermarket crossover gaskets.

That victor reinz kit comes with the crossover gaskets,aap has fel pro crossover gaskets they are labeled under water pump gaskets.out of those three brands AC Delco,fel pro or victor reinz are any better than the other? Also do you remember what size the quick disconnect tool for the fuel line is?

MC,I was reading your thread on your crossover job, what green silicone hoses were y'all talking about being changed?
- 02-15-14 09:55 AM #37
I used permatex high temp thread sealant.
Not sure what size disconnect you'll need, but cheap ones are usually sold in a kit anyway.
I used A/C Delco gaskets. Victor Reinz is a name brand as well. I wouldn't worry too much about it.
The silicone hoses are for pre '00 cars.

Ok, thanks on your crossover thread someone said the fuel disconnect tool was 3/8 .

I got a coolant pressure tester today to test the system .first the radiator cap won't hold past 16 psi , once I pump the pressure past 16 psi I could here the pressure hiss, so basically the cap only holds 16 psi.so I assume I need a new cap.also when I pump the system to 18 psi I couldn't find any leaks and it held the pressure for 5 minutes or more till u relieved it.I can't find a leak but I have seen coolant on the top crossover gasket before (not a lot ) and there is dried dex cool around the crossover gasket close to the water pump.idk maybe it leaks worse in really cold weather which we had a lot of the past month.

Some of these cars do have 16 PSI caps.
You could go up to 20 PSI for the test if you wanted to. If it's just seeping, you may not hear any hissing during the test. You leave it pressurized for 30 minutes or so and then check it. If the pressure dropped, you look for the wet spots.

Yea my cap says 18 psi but won't hold past 16 psi, should I get a new one or will it not make a difference? I actually pumped it up to 19.5 psi and left it on there for five minutes or so and it never dropped,I would if let it sit longer but I was already out side for a while and I didn't want to leave it while I was inside being that I live in an apartment.if a gasket is starting to go bad would it leak worse in really cold weather?
- 02-16-14 06:06 PM #42
The 2 PSI won't make a difference as far as the leak goes, but the cap is faulty and should be replaced.
Ambient temps don't make any difference once the car's running, the gaskets/seals are touching 200+ degree metal and coolant. While the engine is cold, theoretically bad seals should leak worse, since everything is contracted.

Yea I read somewhere when the crossover gaskets first start leaking its usually after the car is shut off and cooled Down , and we have a had a lot of really cold weather this winter (-0 a few times ) this has been the coldest winter in twenty years here. I have seen a little dex cool on the top of the crossover gasket after the car has cooled off, its leaking more underneath where I can't see.I'm going to have to wait till it warms up before I attempt to fix it.are Stant radiator caps good to use?
- 02-16-14 07:05 PM #44
Stants are just fine.

Re: 2003 STS coolant leak (possible crossover leak)?
ok,weather should be good here this weekend so hopefully ill change the gaskets then,one more thing does the egr inlet pipe need to be replaced when doing the crossover,i read that it has a crush seal and the whole inlet pipe has to be replaced if removed.
