L.G. is right, some leaks won't show until pressurized. My radiator didn't leak until reaching operating temperature (system is pressurized), then the leak was visible, from a crack in the top radiator plastic reservoir. Also, do a compression test, you could have a head gasket leak. Good luck, Dave
just idle the engine, any you will bet 12.5 pSI , (the rad cap does that)
or drive around block and then idle it and just look.
you will see the leak. 12 lbs is plenty of test pressure , really.
if not ,then the you have a bad head gasket or cracked block or head.
are you running the proper ration of Antifreeze and water.
they sell a Radiator Hydrometer for $2 at most stores.
there is another test kit that attaches to the rad cap called the combustion gas tester.
if you have any leak at all, from water jacket to cylinder , it will show this fact.
looking in the overflow tank for brown or worse black soot is another clue.
the tick is to not leave the drive way, so you can see the puddle.
a compression test may help too. all cylinders must be equal. look careful.
look at all hoses , even the hidden ones, and on the right side, fire will inside and outside for the green puddles near the Cab heater radiator.
thanks you guys -ive got this sidekick on an island in the bahamas and two blondes decided to take it to lighthouse beach at the southern tip of the island today and not check the fluid. they arrived back with the vehicle overheating and i no longer have a problem finding leaks. im seeing one on hoses that go to the heater core and im hoping the other one is coming from the heater core itself. i sure hope they didnt fry it. can i join the heater hoses together and bypass the core?
yah mon the bahamas is great but the two blondes are nothing but trouble! im sort of isolated so getting suzuki stuff is a bit of a song and a dance. i couldnt even find anyone with a radiator pressure cap so i could pump it up. but the fishing is awesome!.
