Hi all
I had the cooling system flushed on my 92 deville the other day at a local shop, and now i still have smell of coolant when the engine is hot. (It did not smell prior to the flush) Can anything go wrong during the flush itself that may be my problem>? Thanks

Open th ehood, start the car and increase the rPM to some 2000-3000 by moving th elever connected to the plates in th ethrottle body (lever which is moved by ISC motor plunger). Watch carefully the "T" a plastic heater valve which connects coolant hoses on the back of the engine. My T developed a tinu crack and under higher RPM coolant fontained out of the crack to the hot exhaust manifold. There are other possible scenarious. Also check out all the hose connections the guys could disconnect for flushing purposes - radiator hoses, thermostat etc. High RPM's help to pinpoint the troubled area. Good luck.

It might also be, as someone stated in another thread, coolant that was spilled on the engine and stuck in a pocket. It takes longer for the coolant to evaporate or dry up than water and you will smell it until it has dried or is washed away.

Once you have double checked for leaks in your system and are satisfied that there are none you might want to hose your engine down (Cold) to rinse out any residule coolant.

One other thing, did the shop that performed the service add the GM pellets or the Barsleak equivalent? This is very important for the health of your engine and cooling system. If they did not add them you can do it yourself at any time.
