I'm a new w140 owner and I would like to know what are the most common problems that arise especially when driven in hot temperature areas.

check heater tee if it was replaced recently Wiring can go bad on certain yearsbefore 1996 check if harness replaced.I do a extra thing on my vehicle to control engine heat,I wrap my exhaust,to make underhood temps. lower.I run non stock thermostat.

Thanks a lot chief... Wanted to buy new engine mounts, replace fuel pump and buy new shocks. Pretty costly.

oatianyi

Oh, and what's the highest HP I can twick engine to? What do you wrap the exhaust with?

oldsinner111

well you could add a nitrous 150 shot with stock internals.I bought my unit through ebay used for $250.
Fuel pump,I use pelican Parts OEM stuff,I have 185,000 on my fuel pump,I will change a 200,000 miles.

oatianyi

Yeah... Pelican parts is where I wanted to buy them parts. Thanks a lot bud.

The reverse going out is a common problem to.

On Most MBs reverse is first to go out. you may need a rebuild however there are springs and things I would check first.Try www.benzworld.org the w140 section

If I was to order myself a heater tee for the M104 in my '95 S320, what part number would I use - I see there is a tee (thermal valve) going to the air collector unit (that breathes from the hood vents above), and another connection directly through the fire wall...made by BEHR.

I buy 99.9% of my OEM parts from ebay.

Hey guys thanx for the info bowt the w140.I want to buy a first car but the thing is in my area in Zimbabwe,people have a negative thing about mercs.I am tall and want a technologically gifted merc and i was thinking of getting either the w140 300se or the w210 e280 or the least i would want is a w202/3 c200.whats ur take on this and what should i get.PLEASE HELP A FEllow.

oldsinner111

my understanding is E,and C Class are lesser vehicles,in terms of quality.I won't buy one,I perfer the w140,or w126.

Vic200

So what would u suggest I get as a car to live with for quite a while

older clk for savings w140,w220 after 2004.CLKs are sporty,they make a v6,but the turbocharged v8 would be fun.

I have the older CLK(a208) convertible and a S500(c140) coupe. The CLK is more sporty to drive on twisty roads and to manage in tight places for parking (smaller and lighter weight), while the S500 is a great cruiser, really quiet with more than enough power to make you smile. I have found the S500 to be less costly for maintenance and more reliable, but you can't put a price on top down crusing!!! Both cars are fun but you need to budget for maintenance as you are looking at 10 - 15 year old Mercedes and things will break on any car with that age, but the cost shouldn't be extreme if you buy a well maintained model and you have a proper inspection conducted before you buy.

oldsinner111

yes for the w140s up to 96,were headgasket,and engine wiring bad.My 99,has never had a headgasket problem on the m104 engine.The v8s I heard you have to watch for the cam oilers to break up.I would look for the metal replacements.I suggest running mobil one syntheic ATF.my w1216 diesel I use a mix of syntheic ATF,and conventional ATF.I buy the Coastal Brand.
