BG OverHeating

[BULLET]

I got a BG Astina DOHC
i have been driving about 50kms down the Fwy and goin about 100kms the whole way.
But after about 40kms of driving the car has been overheating and the temp guage goes all the way up.

Dose anyone know what it could be?

FIRST! before trying to establish where water is coming from/going???

a) check coolant level
b) check radiator fluid consistency ie: oil in radiator? ie: drops of green in oil?
c) check oil level ie: water (whitish colour) in there?

OK? NO!.......fill radiator with coolant/water, including reservoir, & watch temp on dash panel whilst, try determine if pipe/line is leaking. This will take great care if water is leaking out fast!!!!!!!!. If so, turn engine off before too much coolant lost!

OK? Yes! now check for blocked radiator. Run engine (from cold) with radiator cap off ((checking carefully temp rising on dash panel)) If it is rising too high, & there is no flow happening, may be blocked radiator.

Keep us posted

this is the 5th overheating astina in a month...
i'm beginning to think they're made for it? lol

I have heard the BP engines are known for this?

Common problems with the BP

Radiator Blockage/ Cracked Top Tank
Water Pumps seize/ Leak
Heater Hoses Block
Thermostats Screw Up...<<<Probably the most likely cause considering your detail of how and when it happened...

it is the season for overheating.
i'm beginning to think drivers aren't doing regular weekly checks under the bonnet.

I agree with Ryan... check oil, coolant, brake fluid, pwr steering fluid, tyres and their pressure, etc EVERY week. I do it saturday morning. most of the time everything is a ok and im thankful that I checked if something is low!

since i busted my car i've checked oil and coolant weekly... the others seem to hold steady

180's and other imports have the same problems due to them being built for much cooler climates...that's why I invested in a Koyo Radiator straight away...

Maintenance - getting car serviced and weekly checks these cars are over 10 years old now

First thing I noticed with the MX5 was the large surface area it has (rad that is) & heaps of engine bay room. Never tries to get hot The 323 turbo had original tank but it never got hot.

Just as Maztech suggests, check/service in this weather. I frequently check all fluids religiously. Even look @ tyre pressures pretty often. Better to be safe than sorry! Both my cars are over 20 years old but are in excellent nick! They get maintained regularly

In summer this problem can be when exhaust header cover not in place. I had same problem when one summer in Estonia was +30C and I drived from Tallinn to Võru. Engine overeated on one side 3-5 times. When temperature was cooling, after tat was´nt any problems. Some time later with friend we was talking about that and after looking under the hood was problem reason known. In my car is Mazda factory sport header(like custom headers for turo engines) what build in strats for BF GTX engines(maybay Mazdaspeed detail) and I don´t have cover on header. Header heats te radiator and air what cools radiator was to warm even riding 120 km/h. Behind other car can´t ride even with 90km/h.

if its a DOHC its the same as the BA DOHC compressor. i had to change my AC compressor few months back and found out that it was the same.
