Some typical car problems involving the engine include:
Dirty oil — it should be changed periodically and the oil filter should be maintained as well.
Coolant loss — a leak in the coolant system can cause engine overheating.
Clogged radiator — a clogged radiator can also lead to engine overheating.
Bad spark plugs — an engine will not properly ignite with defective spark plugs.
Oil pump failure — this could starve your engine of oil and cause serious internal issues.
Some of these common issues with car engines are minor if addressed early, but can magnify into major, costly issues if they are neglected.
