Overheating, cold start, rear suspension
I have several questions. Hopefully, someone can help me with each of the questions. 1. Auxilary fan - auto boil over, 2. Hard starting, 3. Rear suspension.
1. Auxilary Fan: I have 1986 190e 2.3 16valve benz. At what temperature does the auxiliary fan engage? While driving around the city, temperature is just above the 80 degree mark. When I come to a stop sign, the temp gauge starts edging towards the red line. When I start driving again temperature starts going down again very slowly. While driving on the freeway going between 55 & 60 mph, temp is just above the 80 degree mark. When traffic slows to a stop and go situation, temperature starts edging toward the red line. While temperature was edging toward the red line, the auxilary fan never engaged to cool the engine down. Is the purpose of the auxiliary fan to cool the engine at high temperatures? After coming to a complete stop and parking the car, I've noticed the overflow tank was spuing out antifreeze (boil over). I had to add additional antifreeze/water mixture to the overflow tank so that I could go home.
Help in this area would be appreciated. Note in Nov of 2004, I replaced the radiator with a new one. On Apr 8, 2005, I replaced the thermostat with a new one rated at 87 degrees celcius.
HOW do I test out the Auxilary fan to ensure it is working?
2. Hard Starting: In may of 2004, the voltage regulator and ignition switch was replaced on my benz by German Motors. Ever since then I have had difficutly starting the benz. It takes between 5 and 7 ignition swithch engagements to start the the engine. During each switch engagment, the engine cranks over about four times trying to start. It seems that after the 5th switch engagement the engine will turn over and start. In January of 2004, I was experiencing the same thing.
I took the benz to German Motors and the mechanic said he soldered something (do not remember what) to allow enough electricity to flow so that the engine would start.
I've looked for the repair order and can not find it. I've called German Motors and the garage has changed ownership. Mechanic who worked on my auto is no longer employed there.
Last week I put in new copper plugs, new spark plug wires, new rotor, and new distributor cap. I'm still having cold start problems. I read an article on the Mercedes 300e and the OVP RELAY. Could my problem be the same? Need help. tired of the approx 7 switch engagements to start car.
3. Rear Suspension: One of the rear hydrolic shocks was leaking so I replaced both with new hydrolic shocks. I also replaced the hydrolic pump. I was told by xxxxxx Motors (new owners) it was bad and needed to be replaced. I do not want to take my car back to xxxxxx Motors because of new owners, and I feel I got screwed replacing a part that did not need to be replaced.
Anyway, I do not know why the rear end keeps bottoming out everytime I go over a small bump. Ride is terrible. Feels like I never installed new hydrolic shocks or replaced the hydrolic pump.
Recently, I purchased two accumulators . I have not installed them yet. Before I replace the accumulators, how do I know the old ones are bad?
A friend at work told me I should bleed the rear hydrolic shocks. Is this necessary? If it is necesary, how does a person bleed the rear hydrolic shocks? Or does a person bleed the accumulators? How is this done.
Terrible bumpy ride. Sometime I feel like taking the 190e 16v to the junk yard. Love the car so I keep pumping money into it. Wife wants me to junk the car.
