Over Heating HELP NEEDED


brother just had the same on his lotus v8, was rad problem, better rad fitted fixed.
 
How much water did you have to fill your rad up by after it cooled down?

Might have a small leak somewhere, I had a slit in my top hose that leaked a lot of water and the temp went up. Might be worth getting a pressure test done? My mechanic attaches this pump thingy to the rad and pumps it up. I also once had loose coolant hoses to the iacv that leaked... Is it filling up the header tank after a rag? could be the h gasket in that case?

Someone spoke about the thermostat going. Mine perished and now I don't have one at all after we removed it. (had loads of bits of black **** in the coolant from the material of the thermostat).
 
Was the heaters getting hot and then blowing cold? This would suggest HG also. I'd perform a compression test and a block test first.
 
I wouldn't worry too much. My car has over heated a few times in the past. No damage has ever been done. I'd put my money on thermostat being the problem. They stop openning, can take longer to open....
 
Good old uncle Tama :)
you may as well replace it with a better/bigger rad while your there
 
I'd just fix what evers causing it to over heat and go from there. You'll most likely be OK.
 
bleed coolant, when i had this problem it was due to trapped air bubbles. should be the first thing you do.

Its not leaking and the hoses are solid i checked this morning and i didnt have to fill it at all, the levels were fine. Ye i may get that done but im hoping its just the thermostat. I am going to check the thermostat first i think it may have just been sticking. Thanks

The heater blew hot air the hole time which would make me believe its nothing to do with the block or head.

Will also be doing this before i get a new rad. Will do this on monday iv heard its common enough for that to happen!!


Thanks for all the feedback guys! Greatly appreciate it :thanks:
 
Good luck with resolving it. It's always alarming when that heater dial goes up! Let us know what it was once it's sorted dude :)

Thanks, had a look today with my mate and found that it is the thermostat dropped it into a bucket of boiling water and its did not open. Then dropped it into cold water nothing happened. Also flushed the rad so i ordered a new thermostat from Honda 36euro ( not so bad ). Hopefully will be all sorted by the weekend! Thanks for all the help with this!! :nice:
 
What color was the coolant when taken out of the radiator?

It was a light blue colour, the radiator seems fine and the hoses do aswell but i will be replacing them since this has come up!
 
Well the car is sorted and running fine again! It was the thermostat, i got a new oem one from Honda for 36euro and i bought 5l of Honda coolant aswell! So i fitted the new Thermostat this morning and filled the radiator back up (made sure all air was out of system) and its fine again! What a relief! Thanks for the help with this!
