Laws and regulations that effectively protect everyone on the street are instrumental to driving traffic crashes down in New York City. While the City Council has. Episode 1: Man inside the hard drive. Scientist recently pointed me out to his colleagues. “That is not Carl Zimmer,” he declared. The scientist was Mark Gerstein.
Hello, We have had our Town and Country into the same shop three times in the last month. The first time was a new Radiator, the second time it was overheating and they replaced a belt. 3 days after they replaced the belt, it started overheating again and we brought it in and they said there was a crack in the engine block.
What would have caused this and why did it happen all of a sudden when they just fixed the fact that it overheated 3 days prior? I don't know alot about vehicles but am I right to assume that either it was already cracked and they missed it or they didn't fix the real problem and it continued to overheat and crack? Help please!! The integrity of the water jacket can be pressure tested. The problem with the sealant type of fix is that it depends on the sealant filling and staying in the crack.
When the engine gets hot the metal expands. The sealant and the block will expand at different rates and often the seal will fail.
Not very different than filling the joints around a window with caulk. Looks good and stays tight for a while then expansion and contraction makes cracks open. If the leak is not extreme you can drive the car and carry a few gallons of coolant mixture. Installing a real temp gauge might tell you when you need to add more coolant. Don't depend on the cars instrument. If you are locked into the car shop for a rebuilt engine. Alc850 Realtek Driver Windows 7.
If not sell or trade it in. The cracked blocked was likely caused by the overheating 3 days prior. It was just not realized until you put the car back on the road with cooling system serviced and working properly. Usually, overheating does not result in a cracked block, or head, but there are other factors to consider like how long was the car ran hot and the engine make and type. Some engines are simply more prone to crack when they overheat, and some are not, ask anyone who builds demolition cars, they look specifically for motors that have a reputation as die hard, will run a long time while getting very hot with minimal damage. Not using antifreeze causes problems that a lot of folks don't realize.
Not using antifreeze in the winter most of time does not result in direct damage from water freezing in the system, it causes your engine to overheat, and that is what cracks the block, not the freezing water as you might think. Your block has 'freeze plugs' in it designed to pop out if water freezes and expands inside the block. They are simple and inexpensive to replace. What happens is water in the radiator hoses, or more exposed areas of the cooling system freeze, which in its self does no damage. But when you start the car, coolant cannot flow, in very short time, you end up with an overheating situation simply because water cannot flow through the radiator in its proper cooling loop. Low antifreeze levels can actually cause the water in the radiator to freeze while driving down the road.
