Not Overheating, Smells like really hot antifreeze after I drive, a/c ok heater heats but when stopped air gets cold...stummped..thermostat?, Leak?


check your hoses and make sure its not getting low because when it gets low the hoses can get hot enough to expand and spit out antifreeze without overheating

Why would my heater blow out cool air when sitting still and then hot air when going down the road and then it's not all that hot


Try flushing or blowing high pressure air through the heater core lines. its sludge build up and need to be flushed through heater core only. check antifreeze fluid level. only put in straight antifreeze, do not mix. most people do not know what mixture should be, so be safe and add straight, it will not hurt it, i run 100% straight antifreeze and never had a problem or worry about it ever freezing and cracking my block, heads or radiator cracking.

Why is there a gurgling sound upon starting and the antifreeze blows out


Check head gasket. Pull spark plugs and perform compression check? Check plugs for fouling. Check engine oil for water/antifreeze
Hope this helps?

I have a 1998 chevy 2500 4x4 6.5 diesel pu.truck starts and seems to run normal ,maybe a little loud, i heard chevy diesels this year are louder than fords etc. blows a little white smoke at startup some...


the head gaskets are blown you can believe that anytime on any engine gas or deisel that you get oil in the radiator and there water/ antifreeze in the oil pan the gaskets and or cylinder heads are bad

My rover 25 will not start!the battry has power tryed a boost start as well as atow start.discovered that the water/antifreeze resevoir has a 1/4 inch of ice in it does this mean i have seized my engine...


let it thaw out ,then see if you have popped a core plug ,if no leaks then put in 3 litres of pure antifreeze and then try starting .petrol or diesel because if its diesel then the fuel could be frozen as well
