My 91 Civic sedan is having a coolant issue. The wierd thing is, there is no puddle on the ground indicating a leak from the radiator. I'm thinking its a smal hole somewhere. Whenever I fill up the coolant reservoir its empty in no time. There is no white smoke comming from the tailpipe so i dont think its a head gasket. Anyone have any ideas?

 

its the headgasket

it doesnt smoke until u low on coolant


at least for me it was

 

it doesnt get pushed out into the resv tank??? if it does and u see no leaks..try a new cap..if not disconnect all major hose and check for rips at the edges.you may not see the leaks since the motor boils away the water under pressure from the motor running..

Or take off the timing belt cover and see if the the belt is wet after a drive...water pump

dunno, tried.

 

try this, take the cap off the radiator, disconnect the dizzy wires, and have someone crank the engine for you, make sure you do it with the radiator full, and watch the coolant in the radiator to see if it bubbles/boils while it cranks, if your HG is blown, the coolant will usually bubble
