The first thing I'd do if I were you would be to replace the radiator cap. It should be holding pressure and if it isn't it's likely that that may be a part of your vanishing coolant.
A radiator cap is pretty cheap and likely to solve the problem.
I wouldn't recommend replacing any other parts without more investigation but the cap is an easy fix and if it works you're all done.
92 camaro rs dissapearing coolant?
Hey guys i have a 92 camaro rs automatic 3.1v6 . The coolant is dissapearing i have to add a gallon every week. I dont see any leaks but when i unscrew the radiator cap it doesnt seem to be pressurized? I want to fix this problem but i dont want to replace parts that wont solve the issue. Help!
- If the cooling system isn't building any pressure and you're loosing coolant its time to have have an inexpensive *cooling system pressure test done as soon as possible to find your internal or external coolant leak.00
- I additionally agree that it may desire to be the engine temperature sensor. I actually have a ninety one Firebird with the comparable engine and it did the comparable factor as yours yet it would basically do it whilst at a end. whilst i might decelerate it would chug and whanot. examine it out- it would be left of the thermostat housing in the direction of the front of the intake manifold. I replaced mine and have not had any subject. what number miles are the automobile by the way?00
- I believe you are losing coolant from the bottom of your water pump. There is a weep hole that has a seal over it that breaks when the water pump bearing gets loose. Likely the pressure does not build up until you get the car up to freeway speed and then you lose coolant . And if the cap is old, replace it as the other answerer indicated it is an important part of the cooling system. Get the front end up in the air and look under neath with a flashlight at the weephole under the water pump, it is likely super clean from the hot coolant pouring out all the time. Replacing the water pump and the cap should help a lot and the car will run better. You need to get all the air pockets out of the heater core and the water jackets so turn the heater on fill up the car (use distilled water or purified water and coolant) while cold, start the car and let it idle ( oh yea, replace the theromostate too) until the thermostat opens and the coolant starts to circulate. Rev the engine slowly several times to try and get air pockets out put the cap on, drive the car for five minutes kind of hard around the block then park and leave it alone for several hours. As the coolant cools the overflow should suck coolant into the radiator until its full. Start it up again, drive it around and make sure it does not over heat, and park it again after 5 minutes or so and let it cool then check coolant level radiator should be full. good luck.00
