The original radiator cap design was blamed for some of the issue, but there probably are a number of causes, including owner neglect and normal seepage. It is a good idea to check the level of the coolant reservoir tank with every few gas fill-ups. In particular, the amount of emulsifiers, rust preventatives and biocides decrease with lube use and over time. If the coolant is low, top it off by adding clean, drinkable water to the coolant reservoir [source: pontiac].

Coolant or antifreeze is one of the most important fluids in your car. There is no internal filter, nor is there a transmission pan to drop. coolant condition should be checked every season as it does deteriorate over time and the % ratio will drop topping up with normal water is another method of lowering the % point check with a radiator shop or dealer service center to get the correct % of antifreeze for below freezing conditions and keep it at that point. The 2011 factory level was way too low as it turns out, and can drop lower over time due to evaporation in the hot climate and charging boil-off. check the coolant level after a day or two or driving to verify the level is still correct. Yes, if serviced any of these fluids may have to be topped up but once correct any large drop in level should be fixed. The water does not get 'used' and circulates around the engine and radiator, so the added strawberry flavour should have no detrimental effects unless it reacts with the coolant (which I doubt).

Often only a top up is required, to substitute any fluid that has evaporated out of the system. I wouldn't worry about a slight decrease in the time it takes to get to operating temp. Check coolant level in the coolant reserve/overflow tank and the radiator. Run it up to operating temperature. If you are sure that you are losing coolant, that it is not simply a matter of a fluctuation of the level in the overflow tank, and you c. The mineral/sediment content in regular water will eventually drop out of suspension and clog your heater core/radiator later on as the coolant ages.

A little background: This car has never leaked coolant, I flushed it a year ago and replaced with G12 (or G12 plus, but the correct stuff in any case) and have never added, but check frequently (usually check all fluids at every fill-up). If we top up to the High Level line on the overflow reservoir with the engine cold, how long would it take for the coolant level to drop down to the Low Level line, again assuming normal losses only through evaporation, etc. 2016 Challenger Hellcat 4000 miles. After about 30-sec total of starter rolling over, the engine finally started and purred. so today changed 'o' rings in the head but while trying it today i noticed the fan was not running as it shuld.

The coolant levels can change from each initial start to the next just due to atmospheric pressures at any given point in time but they should not vary any more than a half an inch up or down inside the tank. I rember with my Audi A2 coolant pump was leaking so coolant level was falling more severely. My guess is that it won't puke. If we top up to the High Level line on the overflow reservoir with the engine cold, how long would it take for the coolant level to drop down to the Low Level line, again assuming normal losses only through evaporation, etc. Seems the coolant loss happens over night when cold. I had a head gasket go on a Mitsu 2. Moreover, while hot, the level will expand and not show the accurate status. The coolant level should stabilize.

Show Full Signature Sapphire blue '04 V6 6 speed w/ full HFP, comptech ss, momo shadow, TL-S 27. The brake fluid is fine. That is, the level of coolant in the recovery bottle should rise as the engine reaches operating temperature. As far as coolant speed, coolant needs to periodically almost stop flow in a street car to give the radiator time to do its work, not because coolant flowing faster doesn't remove more heat but because the radiator cannot keep up. Coolant level will drop significantly - add coolant to make up the difference, and install the radiator cap. To avoid this, pull over and shut the engine down as soon as possible. here's something you can try,when your car is cold,take off the cap,start the car and fill the radiater while the car is running,let it run until the thermostat opens up,the coolant level will drop,put in more coolant (just enough to fill it up to the top),once the coolant level starts to rise,put the cap back on the radiator and run it. The extra drop to the bottom of the reservoir could have been due to the recent outdoor temp drop to -7C. But after operation, the radiator will give off a hot moist smell and show signs of leaking underneath.

What does coolant spraying all over engine mean? If you mean for Coolant level sensor it is on the bottom of the plastic coolant dish on the passenger side of the car. If the fluid level drops, it may turn on the warning light. If it's lower than that, add enough to raise the level to the "Full Cold" mark and not higher. Basically, it's normal to have dried coolant around the weep hole of the water pump. This was the SECOND time since late December 2017. Engines in modern cars are not designed to withstand high heat for extended periods of time, so if the coolant cannot do its job, you could cause serious engine damage that leads to major repairs. On both was on dual carriageway or M25 so, knowing I only had topped up a teacupful last time it happened, just kept on driving watching the temperature gauge which maintained its half meter reading without any change. On reflection I think you're worrying about nothing. It eventually produces the rust powder problems that have been so widely observed (see Motor's August 2002 issue at www. The amount you add will likely be negligible considering how much the entire engine uses so the ratio shouldn't change too much. Mine was in for the fuel tank pressure sensor fix which necessitated the coolant system being drained.
