Coolant/antifreeze is leaking from the A/C evaporator drain and blower module drain. There's also a steady flow of antifreeze from under the car. Coolant mist blew into the car from the A/C, but was still cold. There was also a white, sweet smelling smoke in the car interior.

Except for the air bag system and seat belts. My husband just cleaned and vacuumed the car and that fixed it? Wondering why?

Have spark, fuel gauge is good, fuel injector pulse is good, but the engine dies IMMEDIATELY after it starts.

Did notice that when spraying carburetor cleaner into the intake manifold it would idle, but die as soon as I gave it some gas.

Any help would be greatly appreciated.

I am not sure of how many spark plugs are in my care and how long it takes to replace them?

there is no connection between the by pass lock mechanism and the computero- does it mean the mother board is out of service and does it mean it needs replacement?

checked all fluids appears to be no leak since initially begain to get hot pulled over oil loss reading empty sign of 'blow splatter residue' on top after filling with 4.5 quarts to fill to top of dip stick then driving roughly 20 mins begains to run hot again now reading 2 quarts over full poss pc valve-gasket following splatter being on top ?

loss of oil but then later shows too much

poss gasket or pc valve was empty on oil filled & hasnt leaked since but shows overfull

I want to make sure my car has enough oil. Should I put more then 5 Qts of oil in my car or is that enough???

how do I remove key it?

T.S. Flasher clicks w/switch in off position. R&R switch with new one. no change

trying to change heater core but don't know how or what to do
