data-section-id=\"1mflig7\" data-start=\"8679\" data-end=\"8724\">How to tell if your car radiator is dirty?<\/h3><p data-start=\"8726\" data-end=\"8752\">The most common signs are:<\/p><ul data-start=\"8754\" data-end=\"8854\"><li data-section-id=\"cci708\" data-start=\"8754\" data-end=\"8772\">high temperature<\/li><li data-section-id=\"115v2ss\" data-start=\"8773\"

data-start=\"8921\" data-end=\"8958\">Can I clean the radiator myself?<\/h3><p data-start=\"8960\" data-end=\"8987\">Yes, if the dirt is external.<\/p><p data-start=\"8989\" data-end=\"9073\">For internal washing, however, it is better to have experience or rely on a mechanic.<\/p><h3 data-section-id=\"1tc50yt\" data-start=\"715\" data-end=\"756\">Can I drive with a dirty radiator?<\/h3><p data-start=\"758\" data-end=\"907\">Yes, but only if the temperature remains stable. If the needle rises, the temperature warning light appears, or you smell strong heat, stop as soon as possible.<\/p><h3 data-section-id=\"1xmg78q\" data-start=\"4747\" data-end=\"4792\">How much does it cost to replace a car radiator?<\/h3><p data-start=\"4794\" data-end=\"4894\">It depends on the car model, but generally the total cost can range from \u20ac250 up to over \u20ac700.<\/p><h3 data-section-id=\"738p0t\" data-start=\"2639\" data-end=\"2701\">Can a dirty radiator cause the temperature light to come on?<\/h3><p data-start=\"2703\" data-end=\"2828\">Yes. If the radiator is unable to cool the engine properly, the temperature may rise and the warning light may appear on the dashboard.<\/p><h3 data-section-id=\"1efcgmv\" data-start=\"2830\" data-end=\"2867\">When should I go to the mechanic?<\/h3><p data-start=\"2869\" data-end=\"3010\">If the temperature rises frequently, the warning light comes on, you smell strong heat, or see fluid
