Check your rad cap. This is an 8 dollor fix and is usally overlooked by most people but it can give you the exact same symptoms of a blown head.(these cars do not blow head gaskets as much as ppl think they do, and I have NEVER EVER seen a honda colling system fail). I race an 84 mugen crx and an 87 dx crx and i constantly check my rad caps as that engine can generate some major vacum at hiogher rpms.any leak will throw you throw a loop replacing everything when the silly little chewed out seal under your 20 yr old cap is to blame.When dealing with cooling problems, NEVER assume its a head gasket UNTIL you have worked thru the basic coolant parts one by one. Get a new cap, top up coolant, start car with no rad cap and let run for about 15 mins, sqeeuze your lower rad hose under the dizzy and air intake to "burp" her. replace cap and turn of car.Take cap off again, top up and replace cap. Start and drive as normal.

Is there water in oil or oil in coolant?those cars have bad rep for heads and head gaskets blowing....
sounds like head gasket blew, water sucked into cyl.
check spark plug if might have wet contact from water in cyl.

Rad hose blew gauge went to red pulled over spuddered then stalled tried to start cranks kinda slow

Engine may be tight because oil has fried and deposits are on cylinder walls. Might have even broken some rings, but try changing oil, pull all plugs and add 1 teaspoon new oil to each cylinder. Crank with plugs still out for a few seconds, reinstall plugs and try to start. Good luck.

How to identify vaporlock.

Car running rough? Stalls at strange times but after a few minutes restarts? Could be vaporlock.

Vaporlock is more and more common these days as the fuels change and older cars are running on more and more ethanol. They simply weren't designed to run this fuel, originally.

So the easy way to tell if it's vaporlock is pop the hood once its stalled and pour some nonflammable fluid on the fuel lines. This cools them down and helps it restart. This is a temporary fix. A more permanent one is to get a heat shield installed on the fuel lines.

Technical Explanation: Vaporlock is the fuel boiling and the car does not properly measure it out then so the engine starves of fuel and stalls. The residual engine heat can keep it this way for many minutes.

I'm BAFFLED with a heater issue. Heat went off in my 1991 CRX SI with no apparent reason. Car is not overheating. Coolant in tank is full and it's clean. Top radiator hose is hot; bottom hose

Check the PUMP, there is apump that pumps the coolant from the radiator into the engine, if its broken you will have that problem.

I have a coolant leak at the top rad rose connection what is the top rad hose connected to and why is it it a thermostat housing or what im loosing fluid lioke crazy what do ineed to do to fix...

Yes that is the thermostat housing, your hose is either old or the gasket is corroded and dissapearing. Try changing hose and gasket but while your at it you might as well change the thermostat to. Get some Forma-gasket to seal the housing properly

First check the timing belt. Open the oil cap and have someone crank it while you look inside and see if the camshaft is moving.
