my bro has been driving a 325i four door and lately it has been having lots of overheating issues we have already spent 5,000 trying to fix the problem and just right now i had to go pick him up we pushed that heavy piece of sh.. 1/2 a mile we just got it back from the shop 2 weeks ago they replaced the radiator last year and the past month they put new hoses a new water pump a new fan a new thermostat etc. but it keeps leaking is there a possibility that there is too much pressure wich is causing small leaks some where in the sytem any help would be very appreciated thanks even though this isnt an rx-8

 

"HEY BUDDY" hopefully u dont have haterz on this forum because they will request that the administrators lock ur thread because its not an RX8 topic....i dont care....but theres snitches and haters in here.....just look out. <<---it happened to me...

 

I had overheating probs with my departed Z3. Once the engine overheats, it cracks the expansion tank. Replacing the thermostat (original cause of the problem), you have to also replace the expansion tank.
Common problem with that 3.0 motor. They use plastic impellers in the water pump and thermostats usually go within 50K.

 

thanks i'll make sure to check if they replaced that also. oh and zumn yeah some people are really **** about things lol but people talk about honda and nissan why not bmw.back to topic my bro said the car didnt tell him it was overheating so im more than sure it's a leak somewhere cuz the coolant can get on the motor and start smoking wich it was and man did it smell! lol and when he was pushing it the idiot jumped in the car trying to stop it by slaming the brakes but it was too late he hit a tree it was loud but there was no damage so its cool

 

could be a vac line blowing by which could blow oil back n which would make alot of smoke but iam not sure not there to c it sry cant help to much

 

Here is where I go for all my 328i ills:
www.bimmerfest
www.bimmerwerks
and the BEST resource, google pelican parts. They have several tech articles w/ detailed DIYs with pics and very good part prices for BMWs. They are TOP NOTCH! No affilliation, just a very satisfied customer.

Now, did they replace the thermostat housing? It, like the pump propeller, radiator tank, and expansion tank, is plasitc and can fracture when overheated or with age. Most of these have metal replacements available at the parts supplier listed above. Do you see where the coolant is coming from? Worse case scenerio is a cracked head or leaking head gasket, but unlikely since you say it is spraying.

 

Those piston engines, so unreliable.

 

Waterpumps are designed to leak when they go bad. There is a small wheep-hole underneath it, check to see if that is leaking.

 

rotor housing must be warped.

 

thanks for the link and i didnt have time to check it they took it back to the shop earlier today and yup piston engines are unreliable lol but it's probalbly the worste case scenario cuz all the hoses expansion tank radiator water pump and thermo not to sure of thermostat housing but other than that it's all new.bmw=big money wasters lol my pops has an m3 and he has to buy new tires every 5 months and they each cost $500-600 oh and if tis helps the 325i is a 2003

 

another thing i told my dad to ask the shop if theyre using oem parts as in oem expansion tank and cap and sensors because my bros car didnt tell him it was overheating and if they used the wrong cap it could have caused extra pressure in the sytem

When my Dad had an M Roadster, I ordered a few parts from these guys. Shipped fast and they had pretty good service. They also might be able to help you out with finding out the problem.

 

I think you are missing some of these: . ,

 

+2 for bavarian autosport. those guys are great. a lot (a LOT, its why i went japanese) of my closest friends have bmws.

 

yeah i know but im always in a hurry so i dont really care unless it's for school or something like that

 

you're annoying... Maybe you posted in the wrong section? if it's in general automotive it shouldn't have been moved or locked.

 

umm wow. i guess the meaning General Automotive doesnt mean anything then. but as for TC, i hope your bro problem gets resolved.

 

wrong again.
