Question about 1991 Peugeot 405
Right you could have an air lock in the cooling system,on the highest point at the back of the engine on one of the heater hose if memory serves me right is a bleed screw incorperated into the hose ,if it has one then start engine and add water with it undone and it should blow the air out .if after doing this and it still dont work then check the thermostat which should be on top of the engine in a housing on the cylinder head .now also it could be at the back of the engine near the bottom in a housing just above the drive shaft .which to remove means removing the drive shaft to get at it (diesel) memory is not what it was and i get confused with a citreon which uses the same engine.if it works remember to use antifreeze ,drain a drop out and add pure ethylene glycol about 2ltrs ,if it doesnt work dont waste money adding antifreeze just pull head off and renew gasket but check head for straightness with a flat edge and check liner protusion ,sorry if iam a bit vague here but old age takes its toll and iam sure these older engines use a wet liner which can cause symptons similar to head gasket problems.if it is liner playing up then scrap car as this sort of repair is a specialist repair with special tool and thats if parts are still available,ie the lower seals for the liners and its costly.
