I have a 1.6 auto petrol renault modus reg55.After I turn on the engine if I push a hard break the rev falling down and the engine stop.But only at the first few miles. Any idea for this problem? Thanks


reg codes only work in UK, use real years..... so ROTW can tell.
please, tell what it does good and bad driving, idling , parked, moviing
hot and cold engine, full power from engine on hills.
stalling (it stalls) but when does it stall, under what conditions. hot or cold engine. only at stop lights hot. or>????
when an engine is cold the RPM is very high (iAC device) and it will not stall cold , if it does that is key.
if it never stalls hot. and runs perfect hot say so.
all these, clues build evidence. to what is wrong.
then we do tests.
PS: ever think to get that 60,000 mile (100km) tuneup>> now be it.

Heater stopped working. It still will blow out cold air but no hot air.


It may be your thermostat. When they go out the heat stops. If you rev the engine a bit, or on the highway, if it comes back; you may need a thermostat.

Suburban overheating and air conditioner blowing hot


If you have a viscous fan hub have it replaced as it is not working. The problem you have is that the engine is not driving the fan to draw air through the radiator when idling so the engine overheats . When moving the air flow from driving cools the radiator and so the temp goes back down. If you have electric fans have the codes read to find the fault or check why the electric fans are not working.

How do i put water in my radiator?


you need to replace thermostat and radiator cap.look under hood around engine compartment.look for a radiator cap near radiator,add 50/50 antifreeze and water to coolant system to bring up boiling point.pure water will cause engine run hotter because water evaporate away,remove radiator pour coolant in the radiator until coolant stop dropping in the radiator now some vechicle pour coolant in the coolant overflow jug,pour coolant until coolant level stop dropping and the coolant level stay at cold full mark.start engie let idle few minutes, watch coolant level in radiator if coolant start dropping add more coolant, when coolant level stop dropping put radiator cap back on let engine idle until both top radaitor hose and bottom coolant hose get warm turn off engine wait until it get cool then take a large rag slightly open radiator just a litle at a time to keep from getting scaled.once radiator remove add more coolant if low,put radiator cap back on start the engine let it idle watch the temp gauge if temperature gauge going hot zone stop engine wait until cool then add more coolant,keep doing this until engine stop overheating going into hot zone and coolant level stop dropping,make the coolant overflow jug coolant level stay at full cold mark, dont let jug run empty if so air will get in the coolant system causing engine to overheat.

Have a bmw 316 it over heats when stopped after bout ten mins with the engine still runnin,, also the fans r blowin cold


feel your radiator when the engine is hot, should be hot at the top and cooler as you go down with no cold spots, if you have a cold spot then it is clogged, and it will require cleaning or replacing. Check your thermostatic fan clutch when the engine is hot should be hard to turn, if it free wheels while engine temp is more then normal, it probably needs to be replaced. Hope this helps, let me know
