SmurfyBhoy Posted January 26, 2014 Posted January 26, 2014 Done a compression test last week after fitting a civic rad. Got readings of 165 170 170 170. All seemed fine. Then today started it up gave it a little rev. Steam from engine bay. Both top and bottom hoses go rock hard. Pressure causing little bit of coolant to escape from turbo coolant pipe. Switch off engine to remove rad cap expecting it to explode in my face however comes off releasing the normal amount of pressure. Any other faults that can cause both rad hoses to have so much pressure. ???? HELP. Quote
SmurfyBhoy Posted January 26, 2014 Author Posted January 26, 2014 Also the rad cap on the civic is 1.1 bar. Cap on standard was 0.9. Dont think tht would make a difference tho. Quote
_shaun_ Posted January 26, 2014 Posted January 26, 2014 how long was it running for ? did the fan come on? Quote
SmurfyBhoy Posted January 26, 2014 Author Posted January 26, 2014 Yea fans came on temp gauge didnt go ryt up to halfway at first took quite a while to get warm. No heaters on or anything. Quote
akyakapotter Posted January 26, 2014 Posted January 26, 2014 (edited) sniff test it bud best and quickest way of telling if it has co2 in the cooling system any garage should be able to do it Edited January 26, 2014 by akyakapotter Quote
SmurfyBhoy Posted January 26, 2014 Author Posted January 26, 2014 Seems fine everything smells normal just dunno wot else to check. Gona do another comp. test if thats still okay any ideas as to whats the cause ?? Could a faulty thermostat cause this ?? Quote
akyakapotter Posted January 26, 2014 Posted January 26, 2014 By sniff test I mean a little device that they use to draw air from the cooling system that has blue liquid in it if it has co2 in the system it will turn yellow meaning hg has gone Quote
SmurfyBhoy Posted January 26, 2014 Author Posted January 26, 2014 I know what your talking bout. Will try tht. As well as another compression test. What if its not the head gasket ?? Any other causes of soo much pressure in the hoses ??? Quote
akyakapotter Posted January 26, 2014 Posted January 26, 2014 could be your stat. rad been bled of all air ? Quote
SmurfyBhoy Posted January 26, 2014 Author Posted January 26, 2014 Gona do another compression test with my fingers crossed. If its still the same readings will go from ther. Bled it all correctly. Today is the first time its taken so long to heat up. Thats the only reason i questioned the thermostat. Quote
aaddzz123 Posted January 27, 2014 Posted January 27, 2014 Any white smoke from the exhaust? I'm having similar problems. When I first start the car I get a slight misfire for 1-5 seconds and SOMETIMES when it's warm it will miss a little and I get white smoke. It's very temperamental though, sometimes I can kick it's head in for an hour and it's fine lol. A few of my hoses also leak a little from the joints. Assuming that there is a bit of pressure in there lol... Yet to do a sniff test myself as well. Quote
corofin12345 Posted January 27, 2014 Posted January 27, 2014 (edited) id check the thermostat first.. if the bottom pipe was hard all of the time the thermostat isnt opening.. simple way to know if the thermo isnt opening: when driving the car the temp needle drops.. ?
