thermostat

Got a weird problem with my W124 E220. When driving along in the city/motorway, the temp gauge sits nicely around 80/90 mark. As soon as I get stuck in traffic, it slowly starts going up, and the last time it went up as high as 100-110 :eek: Then it goes down again, when I start moving... Am...

Has any one got any idea how to remove the bolts from the thermostat housing because the heads are gone. I could drill the heads of but i am concerned that i may not be able to grip the screws with the vice grip. I guess they will unscrew once the pressure is off, but are they the type with...

Hi, My thermostat is buggered because cant get any hot air and the temp gauge doesnt move above 45. Just wondered what other problems this could cause because my car went into limp mode yesterday ? Thanks David

Yesterday, while taking my new (for me) car home, it started to develop an overheating problem. I thought it was a sticky thermostat, so this morning I set about pulling the thermostat to test. I was shocked to find the following when I cracked open the thermostat housing...

I'm sure others have done this but I worked it out this morning and I'm quite please with myself :bannana: I was about to undo the bolts and remove the thermostat housing when I noticed that the outlet at the bottom of the expansion tank is lower than the thermostat. I concluded that if I...

Two questions in one thread... I think I'm diagnosing a stuck open thermostat on my new car, while in slow moving traffic, the coolant temperature rises to around 80 degrees C, but when on the open road, it falls to between 50 and 60 degrees. Whenever I've seen this before, it's been a...

Has anyone replaced the thermostat on the W210 E320 CDI? How is it done please??:doh:

Hi Guys, Our car is a '99 E 300td estate. I recently (3 months ago) changed the thermostat. The thermostat is on the off side bottom of the engine, towards the front. The latest thermostat requires a new housing, which was also fitted. I considered carefully which way round the thermostat...

Hi Guys, Looking for some advice... The "slug" was running a little cool with the onset of winter and taking ages to get up to temperature and it would only really get there if it was idling in traffic. So I thought it was probably time to replace the thermostat. I phoned MB in Tonbridge, who...

My 1985 W123 230E (gallery) runs, starts beautifully and gives great fuel economy. She does, however, show low temp on normal running and in these recent cold days doesn't put out much heat. The temp guage on cold days doesn't get much past 60 with the heat on, and it only gets properly warm...

Hello all I have tried the usual searches but so far turned up a fat zero of useful info. I have an overheating problem that is not bad yet but I want to nip it in the bud. On my list after a coolant drain, is to replace the thermostat on my S320. But I cant find any information on how to do...

Next month merc will be towing our heavy caravan while it is already loaded by family and packs. It is a well kept w 124 300 D estate AT. I know on day time the temp indicator will sit slightly over 100 degrees line even on flat roads. Attempting AC or driving on hills will rise it to 110...

What temp should the car run at? It seems to take forever for the it to get to around 80 on a run and then doesnt go above? is this normal? In traffic it can reach almost 100 Is changing the stat on one of these a DIY job and if so where abouts is it? Im not a complete beginner having changed...

Hi Guys! Back again we are also having problems with the E320cdi diesel engine running at low temperature at the moment it is running in the low 70% used to be up in the 80%s on reading several Forums on Thermostat problems, We have ordered a new Thermostat from Mercedes Chester on Monday...

Last weekend I had a new thermostat fitted to my car. I spent ages wondering if it was worth changing as my car has always run at 70 deg and I have heard it said that diesels tend to run cooler on the motorway. The results are great. My car now runs at 90 deg even on the motorway with cruise...

The workhorse has finally started to complain about its health after 155,000mls! its a 1996 VW polo 1.6 petrol & on frosty mornings the temp Gage moves slightly and stays there even after 20mile trip, the heating is still working but not as hot, there is plenty of anti freeze so am i wright in...
