Evan Purple240zt Posted September 12, 2002 Share Posted September 12, 2002 Guys, heres the deal. My car overheats in about 5 minutes of driving time. Steam pouring out the overflow etc... I replaced the HG in hopes to alleviate this problem tonight, and it didnt do crap. Its 2:30am and I need to get this solved tomorrow morning/early noon. Before the HG swap, I was blowing coolant out the overflow tube under boost. I dont think its happening anymore. Any ideas guys? give me what you got, im desperate. The only thing i noticed is that my radiator seems to be full of junk, needs to be flushed. Its an MSA 3 core. Could this be my problem? HELLLLLLLLP. Thanks - Evan Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted September 12, 2002 Share Posted September 12, 2002 A generous dose of Electro Sol dishwashing powder to the radiator may heip to clean the radiator crud out but it takes a few applications with the motor running. Mix up a cup to a half gallon of hot water to start. This has worked for me if it is simply a clogged radiator.Remove the thermostat for this operation. You may want to postpone the trip until problem is solved. A flush kit inatalled will help and speed the process Quote Link to comment Share on other sites More sharing options...
denny411 Posted September 12, 2002 Share Posted September 12, 2002 The fact that coolant is blowing out of the overflow under boost, suggests to me that you may still have a blown head gasket or even worse, a cracked head or cylinder wall. If you have access to a coolant system pressure tester, I would suggest checking that first. Pull all of the plugs and see if the system will maintain a constant pressure level. Afterwards, check all cylinders for any trace of coolant, and check the dipstick before and after to see if the oil level goes up or not. my.02 Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted September 12, 2002 Share Posted September 12, 2002 Denny has a point! Check the oil for tiny droplets (microscopic) of water. The oil will turn gray undisturbed in the crankcase overnite Quote Link to comment Share on other sites More sharing options...
Evan Purple240zt Posted September 12, 2002 Author Share Posted September 12, 2002 Alright guys, after some thinking on things last night (late) I decided that I was NOT loosing boost through the radiator, but it seemed like it because coincedentally, the thing started blowing steam one time. I think thats fine, i hope it is because this motor has 3k on it. Electrasol huh? Ill give that a shot. If i cant get it figured out I wont be able to make it most likely I opened the radiator cap, and there is sunflower seed looking crap in there, i wonder if some dumbass rodent didnt store stuff in there for the winter last year! That would explain things. When I opened the cap last night, it made steam of most the coolant, but the wierd thing was that the remaining coolant SLOWLY drained past the top down into the rad.. this is where i saw the mystery debris. I may take it out and try a backflush Evan Quote Link to comment Share on other sites More sharing options...
denny411 Posted September 12, 2002 Share Posted September 12, 2002 The other day when pulling the engine out of one of the Z`s, I pulled the lower radiator hose off and about two fists full of acorns came out of the lower radiator hose I`ve heard of ginger,pepper,nutmeg and even raw egg whites as radiator stop leak, "but acorns?" HHhhMMMmm, must be some "Alabama thing" Quote Link to comment Share on other sites More sharing options...
Sumo Posted September 12, 2002 Share Posted September 12, 2002 backflush is ideal and dont forget to see if the thermostat is not stuck shut. Quote Link to comment Share on other sites More sharing options...
Guest pvtkary Posted September 18, 2002 Share Posted September 18, 2002 When you remove you oil cap do you have white or opake dorplets on it? Is steam coming out of your tail pipe? Do a compression test! This will either make you sleep better, or help you to make some tough decisions. Also chek your thermostat in a pan of boiling water.
