Note: * \u2013 this temperature represents an average value between the temperature of the beginning of crystallization and the temperature of fluidity. The exact value of the freezing temperature is determined in laboratory conditions. Guideline values can be obtained by refractometers and hydrometers calibrated for ethylene glycol based coolants.<\/p>\n

PRISTA\u00ae Antifreeze Long Life is an antifreeze concentrate based on ethylene glycol and additives based on organic (mono and di-carboxylic) acids, not containing silicates. It does not contain potentially dangerous additives such as nitrites, amines and phosphates and this makes it less dangerous for the environment.
\nPRISTA\u00ae Antifreeze Long Life is used year-round to protect against freezing, overheating and corrosion of engines of cars, trucks, buses, off-road vehicles, stationary and marine engines, etc. Use only after dilution with distilled or softened water. In addition to traditional engines, it is particularly suitable for high-tech engines, for which the protection of aluminum parts from high-temperature corrosion is of great importance.
\nTo ensure good and long-lasting corrosion protection, it is recommended to use at least 33% (vol.) of PRISTA\u00aeAntifreeze Long Life in distilled water. A typical mixing concentration is 1:1, which provides frost protection* at ambient temperatures down to minus 40\u00b0C and optimal cooling. Mixtures with a concentration of PRISTA\u00ae Antifreeze Long Life higher than 70% (vol) are not recommended.
\nThe maximum protection against freezing is up to about -69\u00b0C, which is obtained by mixing 68% (vol.) PRISTA\u00ae Antifreeze Long Life with water.
\nThanks to the organic additives used and their minimal depletion during operation, an extended product replacement period is ensured. The recommended replacement intervals are as follows:<\/p>\n
\u2013 passenger cars 250,000 km or 2,000 h.<\/p>\n
\u2013 trucks 650,000 km or 8,000 h.<\/p>\n
\u2013 stationary engines 32,000 r. h. or 6 years.<\/p>","protected":false},"featured_media":6471,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"pwb-brand":[357],"product_cat":[227,547,222],"product_tag":[548],"class_list":["post-6421","product","type-product","status-publish","has-post-thumbnail","pwb-brand-prista","product_cat-prista-oils-fluids","product_cat-antifrizi-i-technosti-za-chistachki","product_cat-antifrizi-i-i-technosti","product_tag-antifriz-koncentrat","pa_marka-prista","pa_opakovka-4-l","first","outofstock","sale","purchasable","product-type-simple"],"tiered_pricing_type":"fixed","tiered_pricing_fixed_rules":[],"tiered_pricing_percentage_rules":[],"tiered_pricing_minimum":1,"_administrator_tiered_pricing_type":"fixed","_administrator_tiered_pricing_fixed_rules":[],"_editor_tiered_pricing_type":"fixed","_editor_tiered_pricing_fixed_rules":[],"_author_tiered_pricing_type":"fixed","_author_tiered_pricing_fixed_rules":[],"_contributor_tiered_pricing_type":"fixed","_contributor_tiered_pricing_fixed_rules":[],"_subscriber_tiered_pricing_type":"fixed","_subscriber_tiered_pricing_fixed_rules":[],"_customer_tiered_pricing_type":"fixed","_customer_tiered_pricing_fixed_rules":[],"_shop_manager_tiered_pricing_type":"fixed","_shop_manager_tiered_pricing_fixed_rules":[],"_css_js_designer_tiered_pricing_type":"fixed","_css_js_designer_tiered_pricing_fixed_rules":[],"_wpseo_manager_tiered_pricing_type":"fixed","_wpseo_manager_tiered_pricing_fixed_rules":[],"_wpseo_editor_tiered_pricing_type":"fixed","_wpseo_editor_tiered_pricing_fixed_rules":[],"yoast_head":"\n
