Replacing the timing belt on an Interference engine, and doing it wrong, can cause serious problems. Busted piston, bent valve, cracked head, are a few.
It must. I am having my '94 Camaro's timing gasket changed for just that reason.
Bad thermostat, plugged or damaged radiator, loss of coolant, ignition timing is off, faulty water pump, head gasket... and who knows what other problems can cause overheating.
That isn't likely. Most head gasket failures are caused by overheating. Not changing the oil will cause the motor to sludge up and increase the wear on the internal parts.
Yes, it can cause hard starting.
you have a blown head gasket water is getting in to the engine oil
Yes if the outside drive belts are over tightened after doing the timing belt it will pull up on the crank causing extra stress on the front bearing.
Not changing the transmission fluid in a car within 200K would cause problems.
Yes, changing the timing belt on a Renault Scénic can potentially cause air conditioning (AC) problems if the AC compressor is driven by the timing belt or if components near the timing belt installation are inadvertently disturbed. If the timing belt is not aligned properly or if any related pulleys are misaligned during the replacement, it can lead to issues with the drive belt that powers the AC system. Additionally, if the AC system was not properly recharged or reconnected after the timing belt replacement, it could also result in malfunction. Always ensure that a qualified technician performs the service to avoid such issues.
A common cause of problems in cylinder head gaskets is leaks in the gasket. When a leak forms, the gasket must be replaced.
try changing both timing gears
Incorrect timing can cause several problems. One of which is high idling. 5000 rpm sounds high though, there may be other problems as well.
Possible cause is a leaking head gasket or timing chain gasket if the water pump mounts to the timing chain like on a ford 302 cid You probably are leaking into the crankcase through the headgasket. There is a slight possibility that the block is cracked.
