i had closed loop cooling installed on my 05 210. since then i can use it about two days before it runs out of coolant. i dont know much at all about engiens and followed the hoses but could not determine where really to check. any tips would be great.

RE: coolant leak
Radiator shops have a tool that can pressurize the cooling system, and look for leaks. You might need to do that, or have it done.
By the way, there has been some problems with the DEX-COOL (orange) coolant causing problems and turning into jello way before it should in cars. Check at the radiator shop about that, also. -
RE: coolant leak
You need to look at this carefully. Vortec 350s are known for a poorly designed intake/gasket/fastening system that fails and allows the coolant to drip into the block. I second getting a pressure tester and testing....best if you test with the engine hot. You might also consider grabbing an oil sample and have it analyzed for glycol. If the amount is high, your oil will be sticky and the level over full.
Also agree on the dexcool jelly. Don't run dexcool more than 50/50 to 60/40 or over about three years. It tends to jelly up the surfaces in the system.
Keep us posted.

RE: coolant leak
i've got the green dex. it sucks b/c im picky about my boat and the morons at south east in orlando installed the system and i picked it up on my back to alabama when i moved. then i took it to a nauti dealer in slidell and told them specifically what happened and they just added coolant and said it was cool. i assumed they did more than fill it up, but apparently not. i guess i'll just run through another bottle b/c i want to go out one more time before winter w/ my new wet sounds 3some and syn6 amp. oh and i want to stick my kick flip finally. i've basically landed it a few times ahhh. anyway, thanks for the help.Comment

RE: coolant leak
You need to make sure that coolant is not going into the pan! At least check the oil and make sure it looks, smells, and feels normal and isn't over full.
If you get a bunch of glycol in your crankcase...you will ruin your engine.

RE: coolant leak
i'll definitely do that. in that case i might just chill and get it fixed and winterize it

RE: coolant leak
pressure check that thing
any car radiator shop has the tester

Clarification:Originally posted by AirTool
If the test is done with the coolant above boiling temp...it will be hard to find the leak because most of the leaking coolant will vaporize and not drip down the block.
If the test is done with the engine "cold", you may discover some small trivial leaks at block parts that won't leak hot because all the metal has expanded. Again, common on the latest version of the small block chevy. These leaks may "scare" or "bug" you if you are anal like me. So you might be happier not knowing.
I suggest starting the test cold and only pumping to about half the cap operating pressure. If you have a common gasket or hose failure, you'll figure it out now because cold water will be dripping out the leak.
If you don't find the problem by this time, remove the tester and start the engine. Get it up to operating temperature (with cooling water attached of course) and let the temp stabilize. Kill the engine and the cooling water and let it rest for 15 minutes or so. Then do the test...probably at cap pressure. It should hold for at least 15 minutes....hopefully 30. If the pressure drops, keep pumping it back up until you find the leak. If this goes on for a while, check the oil level to see if it is rising due to water dripping into the gallery.
