We have no heat,


I'm going to think about the heat question

Get that trans fluid changed tomorrow

You spin those tires in snow & heat any part of
the drivetrain your doomed

Those are the worst transaxles out there

Not trying to scare you or be hurtful

I once owned a trans repair shop,just do it

My van has poor heat and changed antifreeze and temp hand stopprd working does that effect heat the temp sending unit


the sending unit will not affect heat but if its broken it will effect the fuel control by giving computer false info, i dont think theres a problem with the temp unit, i think the thermostant is bad and is stuck open or you are very low on coolant, if the thermostat was stuck open then you would get some heat not very hot and would take a long time to get heat. i would start by replacing the thermostat, it is very important to bleed air from system after coolant change or thermostat replacing, after filling run engine until fan turns on , let cool some to release preasure then remove cap start engine and top off, drive for 15min then park let cool and recheck coolant, hope this helps,

I have a gmc safari van. we had heat until changed antifreeze & new thermostat. have air but cold air. help


You have air in the system.Make sure the over flow bottle is to the full hot level and start and run the vehicle.Do not let it overheat.Shut it off and let it cool down.The coolant from the over flow bottle should go into the engine.This could taker a while.Refill the coolant bottle to full hot level and repeat til air starts coming out warm.Make sure you put the the heater to the floor heat.Good luck.

OVERHEATING


This could be a multitude of things:

Stuck closed thermostat.

Cooling fan not coming on.

Clogged radiator.

Low on coolant.

Water pump failing/leaking.

Head gasket blown, leaking exhaust into antifreeze.

Clogged catalytic converter.

Thermostat: If the Van heats up, then feel the upper radiator hose. If it's cold, then your thermostat is closed. Replace thermostat.

Coolant: If low, simply fill with distilled water and coolant. Low levels will let engine over heat.

Radiator: If there are cold-to-the-touch spots on the radiator after it should be warmed up, then a clogged is probably occuring. Have radiator flushed.

Head Gasket: If you smell exhaust fumes in your coolant reservois tank, then you got a blown head gasket.

Cat Converter: Only can be tested if off the car. Or you could try a non-contact thermometer. These are also good to testing cold spot on radiator or if thermostats are open.

Cooling fan: If mechanical it'll be spinning. If electrical, it should come on automatically with the A/C, or when it gets hot.

Water pump: Will be leaking from the front if it needs replaced. On a van, it's a tough job.

Good luck!

Over heats but wont blow out heat


th water pump may be out on it you cant always tell from looking. if its over heating that badly id replace the water pump before it goes all the way out on the van.

97 GMC Safari Van - Heater takes forever to blow hot air. Could this be a thermostat problem?


Hello,

Humm I make the assumption that you don't have overheating problems. Yes, sounds like a thermostat is stuck open. If you have a gage on the dash you may also notice that the engine temp takes a long time also. Sometimes when you sit a light for a while the temp edges up and starts to get warm....then when moving down the road a higher speeds the temp cools off again. this does this because the thermostat may be stuck open and it cools the heated water in the engine when moving. Also, check the coolant level in the radiator. (only do this when cold!!!!!!!!) ok????? NOT HOT! low coolant can affect how the heater performs. (low volume)

Hope this helped. :)
