i got the pump, thermostat timing belt , temp sensor all replaced with new.
flushed heater core with water and valvaline super flush whole system.
when car warms up top rad hose is hot bottom is not hot.
once warmed up car has some heat but that fades away in short time.
temp stays at 90 when idle but goes little over when driving sometimes.(90-100c)
any help would be appreciated.
some people say air in system and I've tried bleeding it few times now.
soon as car goes over90c heat seems completely gone
?????

 

Are you sure you installed the thermostat in the correct orientation? The spring side of the t-stat should be facing up towards the block. If the hose coming off the t-stat never gets hot then the t-stat is not opening and is either installed incorrectly or is defective. Did you use an OEM t-stat?

How are you bleeding the coolant?

 

I got the pump thermostat and belt done at a shop. I'll have to get them to check thermostat again. I've got it bled with a coolant flushing machine and then let it warm up with no cap on and run for bout 20 minutes.

 

So like I posted I got new pump temp sensor thermostat x2 cal volume super flush and few hose flushes. Still had no heat. Well it would start out with some heat and fade to cold fairly fast. Unwilling to dump another $1000 for new heater core I read about 30 forums how people fixed there heat. I put together the best points I think of them and fit to this.
Bought a drill pump ,3/4 clear hose , and a bottle of CLR.
Filled a 5 gallon bucket half way with warm to hot water. And half bottle of clr. Hooked up my new hose to heater core outlet/inlet. One went straight to bucket the other went to drill pump then to bucket. Flushed both ways for 10 minutes each then let sit for 30 then flushed again. Repeated this about 4 times. After the fourth time the bucket looked gross. So filled bucket with clean warm water and flushed. Repeated last step with clean water 5 times. Till no more crud was in bottom of bucket when dumping it. Put it back together and bled air by lifting over flow tank up 4" and pulling left core hose out enough the little hole could bleed a stream with no more air.
After all said and done I have amazing heat.
Hope this can help some of you.
