Yesterday is when this all started I was driving everything was fine and all of a sudden bam temp needle rises high and fluxuates up and down up and down there for I parked and antifreeze wasnt pumping through normal so I flew to autozone put a new thermostat on befor the upper radiator hose exploded which it did late last nite on the way to work the needle was at normal after install and reincert of coolant and the hose blew up and I had to get pushed home far to so ill get a new hose today but its bugging me if now is it just the hose or a recheck of the thermostat I put in or is the water pump bad,its a 99 civic dx d16y7 auto

how will I do that I mean I did have the AC on yesterday and this is the first time this car ever did this its weird I installed the thermostat and put more coolant in and everything was perfectly fine till smoke arose and the needle shot up and I hurried to pull over to see that upper radiator hose busted open all over the place so its nuts im thinkin I installed the thermo right I mean its no other way it can be installed or that hose was bad and the pressure got to it or there is another issue but hopfully its the hose,im new to the AC trick you mentioned

might as well call Iceman to make your engine cold while you're at it

He's ****ing with you

Head gaskets done dude...combustion pressure is overpressurizing and overheating the system. This the appearance forum btw, not tech...but thats your answer. Test for the presence of combustion gases in the coolant...that'll verify what i am tellin you. The test can be done by a shop or you can buy the tool to do it.

Your right sibs but I could use the humor and iceman cuz im hot hell right now,but ill buy a hose and see what happens hopefully that one doesnt expand and pop from antifreeze,ill say this I love that civic I got swaps and many plans for it plus a paint job in a week or so

What thermostat aftermarket or oem? aftermarket what temp?

Could be a few things, how old is the water pump?

How old is the radiator?

Might be a clog.

Get a block tester to see if any gases in the coolant, people jump to conclusions and say headgasket.

God I hope you didn't warp the head and block. Change water pump and thermostat with oem parts, refill with coolant and do bleed process. Everyone you get ready to hit the. road check fluid. If its low after 3 top offs than your headmaster has fail and maybe, JUST MAYBE, you will need to get your head check for warpage.

How does it run other then this issue? Agree with RC000E on the head gasket being a possible problem. DON"T drive it tell you do a compression check. Also look on oil dip stick for coolant. And coolant on your oil cap. Somtimes doesn't show up there but thats a easy sign of blown gasket.
