BMW E30, 320i, Model 89 - 91, plastic bumpers

Never done one but all i would do is first have a cup of tea - look at it then decide where the fixing bolts are then undo the fixing bolts and the fog light connections if fitted and any plastic trim splash guards under the car and off it comes .Then go to the local cafe for a coffee

Hi, I,m assuming yours is an E36 model, in which case the main fuse box is under the bonnet , facing the car at the front the fuse box should be situated on the right hand side close to the bulkhead, ( black plastic cover over fuses )

It is on the front of the head, facing the radiator.
Follow either big radiator hose, they are both attached to the thermostat housing.
Your thermostat housing is probably plastic. If so, don't re-use it because plastic housings of that vintage shrink and warp. Buy a new plastic or aluminum thermostat housing.
On a car this old, consider replacing every plastic or rubber part you touch, unless you know that the part has recently been replaced. I have a couple of '97 328s, and I never put a plastic or rubber part back on the car without replacing it. Saves a lot of time and repairs down the road.

YOU HAVE E46 MODEL 325I 325XI 325CI 325IC E90 MODELS YOU HAVE E90 - 335I 335XI 328I I DID NOT SEE 325IE 90 MODEL.I WILL GET BACK TO YOU.

3 blown out radiators....define this. My accord has 224,000 miles on it, same radiator, same clutch. And the beemer blows radiators? Makes 'em explode? Can't imagine anyone making a radiator that blows up all the time. You keep buying the same model?

Anyway, check: air gap in system, bleed the system while it heats up. Water pump. don't see it being replaced. the older ones had plastic impellers. is the auxillary fan working? It should come on all the time when the A/C is on. Clutch on belt driven fan ok? put in a 12 degree cooler thermostat and drill two 3/16" holes 180 degrees opposite each other.

Blown head gasket or two can cause overheating. Bad timing. did you change a good or bad radiator sensor? how'd you test it to determine it was bad? Don't just replace parts, determine they're bad. Replace enough parts and $14,000 later you should be ok.

Either the fan switch on the engine or the fan relay is at fault. Replace both for they are inexpensive to replace

if you have an entire headlight assembly (in case of accident) remove bumper, there are 8mm screws on the inner lining of the fron wheel well where the fender plastics and the air dam connect to the bumper, undo the screws concerning the bumper on bot sides of the car. then remove the plastic cover under the bumper (either philips screw heads or 10mm) and then under the aluminum re-enforcement strip behind the bumper (access from under the car) remove the torx screws that hold the bumper aluminum to the car frame, get a friend to help you pull the bumper off evenly an then seek the 8mm screws that hold the headlamp in place. the headlamp comes off the car strait out the direction of the front. disconnect the wires and connect the new lamp and fasten to the car. then do the assempbly in reverse order for the bumper installation.
for just changing the bulb, there are some rubber seals behind the light where the bulb rests. there are metal clips than you depress to release the bulb. install a new bulb and then replace the rubber caps.

ck for excessive play in the electric cooling fan blades - theses usually only come on when the car is hot or ac is used. You can also check this by locating the fan relay(s) and removing them when you hear the noise.

I believe the upper tie bar can be unbolted and laid over the side because your hood latch will still be connected and then you should be able to unbolt everything and pull it straight up and you may have to take your lower shields off under the bumper

by the fender lights and front and back lights every bmw is designed different from its predisessor even if next years model they still have a design change in the body work with lights and bumpers
