I recently replaced a couple of hoses that were blown out at a professional shop and now my car is having an overheating problem. What happens is after I exit the freeway my car overheats at an alarming rate and coolant goes into the overflow and is boiling. I've taken to the Acura dealership and they said it may be a cracked headgasket but is very unlikely since there is no oil in the coolant and no coolant in the oil. I took it back to the shop that I took it to replace my hoses and they replaced my fuel filter for free but said they couldn't duplicate the problem which I know is utter crap. Anyone have any ideas on what the problem could be?

 

Just cause they didn't mix doesnt mean u didn't blow your head gasket !! Check your thermostat first maybe it failed and isn't opening

 

They replaced the thermostat when they replaced the hose. The main thing is I'm a delivery driver and I refuse to drive my car right now because of this problem and the fact that my temperature gauge is fluctuating randomly. I'm thinking it could be because they put in an Aftermarket thermostat and not an OEM one.

 

A "fluctuating" temp gauge may mean you need to bleed the coolant system.

Because the problem, [overheating] occurs when you get off the freeway, [I assume it does not overheat when on the freeway] I would confirm that the rad fan(s) is/are turning on.

I agree with JoHnnY LonGHoRn, you may still have a blown H/G even if there is no oil/coolant mix, a small leak from combustion chamber into the coolant chamber would not result in oil/coolant mix, what it would result in is hydrocarbons in the coolant, I am surprised the shop did not test for that.

Try this...
Remove rad cap, make sure coolant level is correct, start engine, look for bubbles in the rad, if no bubbles reinstall rad cap and allow engine to get up to running temp., does rad fan(s) turn on?

I will also assume rad cap has been replaced or at least tested, if not do so, rad caps are cheap. 94

 

Thank you everyone for the advice, it turned out to be a clogged radiator. Replaced the radiator and haven't had problems since.
