tips/tricks/easy way to burp cooling system?

[ELVIS]

on a 94 vert? sometimes the low coolant light will come on. its not low or running hot, so i assume there could be air in the system?

god bless.

Fill it up with the upper radiator hose disconnected and wait for coolant to come out.

jack the front end up

those sensors are pretty cheesy though. seems they give alot of issue

Get beer, open one, turn on the music, jack up front end, crank up the car, grab another beer, turn your heater on, let the car run for as long as it takes while adding coolant, grab another beer, grab a chair, and watch the coolant level while drinking another beer.


Whenever you feel like you have gotten it burped all the way, then wait until you see the coolant swirling in your system. At this point I will raise the rpm's to around 2k. This usually gets me a little bit more room to put in coolant.

Cap off your radiator before you kill the car. Top off the reservoir as well.

Now get another beer while you clean up your mess.

That sensor is in the catch bottle. Sometimes the water evaporates out of the catch bottle and the sensor turns the light on. I used to worry about it, but every time i took the radiator cap off, the coolant was to the top. Now I just fill the catch bottle half full and the light stays off for about 3 weeks till the water evaporates again.

Why the f don't they put a bleeder screw on the tstat housing like most jap cars.

This.

For the records, the easiest way to remove air from a SBF cooling system, that I've found - is when you put the thermostat in, drill two 1/8" holes in the outter rim of it. (be sure they are in the path of the water, and not covered by the gasket). When you put the thermostat back in, you orient those holes at 12 and 6 o'clock. Now, when you fill it up, the water can run in the bottom hole and the top hole bleeds the air out back up to the radiator. Never again will you overheat a car trying to get all the air out.
