engine hot
I went for an oil change, next week the temp gauge shows hot i check and there's no engine fluid. i fill up but a week later its all gone. mechanic changes the the radiator and hoses. gauge stays normal but the engine gets really hot very quickly (the rod to hold the hood is hot to touch). Th e mechanic says all is fine but i know something is not right

Re: engine hot
You went for an oil change, a week later there is no oil in there? Then its gone again a week later? So, temp gauge reads normal, yet the engine is hot? What car, year model all that jazz.

Re: engine hot
We are assuming you think they are related. Engine oil and Coolant are two different fluids. How are figuring out that is getting too hot? the engine get very hot after driving it.

Re: engine hot
integra 2001 50000 miles 1.8l the mechanic checked the oil and said it was fine although the gas cap was leaking im thinking thats bec it gets so hot. unless its the other way around but he checked the oil and said it was fine so i figured it wasnt the oil that was the problem

Re: engine hot
Fill and bleed the coolant, If your temp gauge is reading hot, replace the thermostat. Run a better radiator and fans and also a coolant chill additive like from Mishimoto. If coolant is disappearing you might have a leak or head gasket leak. If its getting real hot in the engine bay it could be also your fan not turning on. Theres also after market fan switches and thermostats that open the thermo sooner and the switch turns the fans on sooner to keep your engine a bit cooler, meant for racing or such but it could help if your temps where your at get hot like here in CA.

But properly fill/bleeding the system and checking out the thermostat and thermoswitch does sound like a good plan.
Might need to try a leak down test if that doesnt fix it.

Re: engine hot
I would try to fix the actual problem first, before bandaiding it with aftermarket radiators/fans/thermostats/thermoswitch/additives etc. This sounds to be a commuter, not a high compression or turbo race car....

I agree to fix the main issue before buying or replacing parts not neaded. You said the gauge read hot and there's no coolant, then you filled it up and it disappeared again. I would say fill it more because you probably didn't bleed it right.

Re: engine hot
I have dealt with these same problems in my 2000 integra. First it was a pin hole leak in the top radiator hose, then the bottom hose, then the thermostat and finally the radiator. After all that, it finally stopped leaking and could maintain proper temp in 100 degree traffic with the ac on. I still need to top of the coolant every few months (maybe twice or 3 times a year), with maybe a quart, but it is pretty liveable. I think at some point I may need to replace the head gasket, but it isn't a huge issue at this point.
