Coolant Loss

[paingod5150]

Ok so heres my odd issue of the day.

On a 2G theres basically 2 lights that involve the Radiator fluid level. The overflow light and the actual fluid level light so far as I can tell.

On Friday my overflow light came on and sure enough it was empty as could be. I checked for leaks in the hoses (none) and filled up the radiator and the overflow. I knew that the overflow would piss off and cause some steam but figured no big deal. Overflow empty light went out.

Now my Radiator light will come on randomly indicating low water. Sure enough after it cools down the overflow is full but the waterneck will take 1/3 of a gallon of water before its full.

The lower radiator hose is slightly crushed by my intake. Not enough to close off flow but enough to slightly (and I mean slightly) restrict it. Would that be enough to cause this issue? The only place the car drops watter after a hard drive is under the overflow tank so I am thinking it might be a case of needing a cooler thermostat.

Suggestions?

Thanks.

Note these issues started after putting on a FMIC, Slimline fans, and the intake that squishes the lower hose. That points me towards the hose. The fluid temps are actually lower then they used to be with the stock fans.

I'd recommend running a compression test.
You should have a 180°F Thermostat in the vehicle. Part number is in the Tech Article section under "Engine".
Also try replacing the radiator cap as it may be slightly damaged.

Yes it sounds like you do have a leak. Your hoses might look fine but there probally not. Do the squeeze test, crush the hose in your hand if it rebounds quick you're good, if it feels "sticky" and doesn't rebound fast then it needs to be replaced. Also if one of them is going replace both of them! They have both been through the exact same use and are both in similar condition. You might as well anyways because you already have the antifreeze drained out and a hose is an 8 dollar investment to protect your engine. Also check for any oil in you coolent from your radiator cap and overflow, if you find this your coolent is going out your tail, and you have a head gasket leak. Good luck

If after all that you still can't find the leak, have your coolant system and cap pressure tested (or you can buy the tester at Sears and do it yourself).

If you cannot still pinpoint the source of the leak, get some uv coolant dye at a local parts house. Find or borrow an ultra violet light to inspect after the dye is put in and engine warmed up. Trace the bright green trail to the source of the leak. Good Luck
