overheating

Hello everyone. I'm new to the club. I'm having an overheating problem with my car when in traffic the temperature goes up to 115. So far I replaced the water pump, radiator, thermostat, all three switches, viscous fan, belt, tensioner. I also done the test for CO2. There's no coolant...

Hey guys, My M103 runs a bit warm and as many of you know, overheating it is expensive. I've put together an overheating alarm and aux fan controller. It uses the stock temp sensor. It's fully adjustable through the temp display in the dash. It power the aux fan so it comes on much...

Oh God will it ever end? My 3.5 V6 which recently had new head gaskets & water pump + radiator re-cored and all new hoses is again overheating. I have a calibrated aftermarket temp gauge which is reading 98-100 at motorway speeds and steam coming from the rad cap at a standstill. I have...

Hi, My S320 W140 started overheating one day - heard knocking sounds then bubbling / gurgling and noticed the temp had shot up to 120C. Pulled over and turned the engine off and let it cool down. Couldn't drive it for more than 3 minutes after that having to pull over and let the engine...

Hi, My car has a overheating issue, the A/C doesn't seem that cold and the fan on the radiator does not come at all. The only way to keep it steady is to have the heater on full. I have replaced the thermostat and still no joy. I have checked all fuses and they are working fine. Any...

Greenoaks and Hughes both looked at my CL600 and having paid £850 to both for rodeo test and various diagnostics(different things for each dealer and see if they highlighted other issues), I was handed a rectification bill of £3,700 - £4200 WTF... Started towing my car to several specialists in...

Hi everybody. I've got a boiling coolant issue with my C180. I changed my head gasket last year november. The car has been good till now. At the speeds of 110 - 150 km/h, my coolant boils over and spills away. I changed the viscous coupling almost a month ago. But I've realised that at high...

About a year ago, I sold a very tidy 1990 W124 300d estate to a friend, who looked after it lovingly, driving it and improving it, until a week or so ago the aux drive belt snapped. This resulted in an extremely hot engine and a blown head gasket. In a fit of emotion I have agreed to but it...

I ask if anyone can tell me please where the small electric pump, near the water expansion tank, is supplied power from, and when the motor should run. My one doesn't seem to be running unless of course it's due to temperature control somewhere

I had never experienced an overheated engine until today. But when there are clouds of steam coming out of the bonnet you have to face facts. And of course, all sorts of horrible thoughts go through your mind: has the head gasket gone? has any permanent damage been done to the engine etc...

Hello all, Hope you can help - have a vito 1998 v230 petrol. Only had it a couple of days - having purchased it from Northampton drove it down to London no problems, once I hit London traffic, the engine temp gauge started heading north towards the 120 mark. When moving again, temp comes...

my C63 has now suffered twice from the transmission overheating. I have heard there is a sofdtware update to the ECU to raise the tempature threshold from 135 degrees to a higher number as 135 degrees is considered a conservative tempature. Anyone heard of this update? had it done?

My son has a clc cl2300,53 reg with the 1800cc engine. The cooling warning is on but the radiator is full. In slow moving traffic the car will overheat and if it gets too hot it will cut out presumably due to safety feature. It would seem that the fan is not operating. Any advise please and can...
