Hi,
When I built my car, I bypassed the heating circuit ,normally used to heat the inside of the car, with a loop: the water is just circulating in a hose
running around the engine.
But as my engine bay is quite crowded, and I never found, in spite of many tries, the perfect route for the bypass hose, I'm thinking about just
blanking the in and out ports of the heating circuit on the engine, with blanking plugs.
I have a Sierra 2.0i DOHC. the heating circuit runs from the water pump to the thermostat housing.
Will this be a problem? Does the heating circuit need to circulate, or can it be just blanked with no issue on the cooling system?
Thanks in advance for your advices.
It all depends if you have a circuit the coolant can take around the engine before the thermostat opens?
lots of engines the coolant circulates the engine then out around the heater matrix,a fast warm up circuit.

Simple hose from manifold to pump running forward and round front off engine
I put a screw cap T piece in it as it will be highest ppl t of the system for bleeding.
The head can get hot spots if the out let is blocked

So the two replies above confirm you can't just block it off!
Have you thought of having a hard pipe made up,then just two small rubber joining hoses onto engine?
Thank you very much for your answers.
OK, I understand your points, and I won't block the heating circuit off, and keep the bypass.
As I said in my first post, I already have a bypass hose which is quite tidy I think: it is a piece of Formline hose connected to the engine with 2
silicone elbows, as the in and out ports of the heating circuit are on opposite sides of the engine, and both pointing outward!
The reason I wanted to remove the bypass is that I'm not happy with how it is set-up now, and I couldn't find a better way to route it.
The problem is on the intake side of my engine bay, which is very crowded, and what ever the route I try, this hose is always close to interfere with
something: intake manifold that had to be shorten to fit under the bonnet, the other water hoses, the thermostat housing, the sensors (water temp, fan
switch), the hose to the ISCV, the alternator, the belt to the crack pulley, or even the electric engine loom, etc.
But I'll find a way
Thanks again.
Not sure it the thermostat housing is the same as on a 2000 blacktop but in my tiger I have the heater and bypass ports blanked off. For a bypass you then drill a hole through the top of the thermostat (i drilled 3). This then allows water to circulate. This is what tiger do/recommended
